I was trying to install this device to replace a simple SPST switch in the kitchen that controls our exterior lights, so I could remotely control them from the car. This is a serious code violation, seriously unsafe, and I just don't see how it could work! It's fairly common to run a wire from the light down to the switch, in which case you'd have the unswitched hot wire and the switched hot wire and nothing else (you wouldn't have a second set of wires coming into the box).
Another possibility is that there is a second switch somewhere that controls the light, in which case you wouldn't have a simple SPST switch, but you'd have a SPDT switch instead. You've got two hots (black wires) two neutrals (white wires) and two grounds (bare copper), with one set of hot, neutral, and ground coming through the top of the box and the other set coming through the bottom of the box.
When you measured "load" to neutral, were the neutrals tied together at that point or were you only measuring to one neutral? If your location is correct, I'm somewhat in your area (I live in PA but I work in Owings Mills). I took that to mean the reading was done without the switch in the circuit (ETA: or if the switch was in the circuit it was turned off). The box in question has two switches, the one I was working on, which controls our external lights, and another, which doesn't appear to do anything. I removed the SPST switch, which I assumed was connecting the load and the line (both black wires) and saw 120 volts when I put the meter between those two wires. I didn't try testing anything with the other, non-working, switch or the leads going to it. I'm a little busy with work the next day or two, so I may not be able to get back to playing with this right away, but I'll try some of the suggestions posted here when I can, and get back with the results. Based on this, I would suggest you not make any assumptions about what any of the wires are.
I think the first thing you need to do is determine which wire is which, with no starting assumptions.
Instead of using a multimeter, get a tester screwdriver like this from your local hardware store. 2 black wires (old, fabric coated) coming in from the top left, both connected to the working switch. Checking for voltage with my multimeter, I get 120 between the two wires connected to the working switch, and between no other pairs. Using a screwdriver-type tester, I get tone at one of the black wires on the working switch, one of the white wires, and one of the black wires on the non-working switch. On the right side, you have newer cables (Romex™, brand name for type NM plastic cable), with one of them bringing in power from the house breaker panel, the other running on from the switch to whatever it controls (probably half of a receptacle for a floor lamp somewhere in the room).
So when working with this, these 2 switched & the wires to each should be treated as completely separate circuits -- like they were in separate boxes. Oh, to answer your original question -- that device won't work on a switch loop wiring, which is what you have at that box on the left side). I bought a number of these cool Insteon devices in the hope of being able to remotely control lights and other things around the house. Sal Culosi is dead because he bet on a football game — but it wasn’t a bookie or a loan shark who killed him. An important part of these efforts has been the development of the Integrated Power System (IPS) for All-Electric Ship applications. IPS offers a number of benefits, most notably reduced costs of ownership, increased architectural flexibility in comparison to mechanical drive ships, quieter operation, and increased survivability in battle conditions.
IPS enables a ship's auxiliary electrical loads, such as pumps and lighting, to be powered from the same electrical source as the propulsion system, eliminating the need for separate power generation capabilities for these loads.
While the integration of power generation systems offers many benefits, the introduction into the mix of new technologies such as advanced power electronic systems, intelligent control systems and state-of-the-art energy storage technologies increases the need for real-time power management and power system reconfiguration, especially in the event of equipment failure or when a ship sustains damage during battle. Based on Opal-RT’s eMEGAsim Real-Time Power Grid Simulator, the simulation facility developed by Dr. Opal-RT also provided specialized software tools such as ARTEMIS and RT-Events that support multi-rate fixed-time-step real-time simulation of power systems with dramatically improved computation speed and accuracy.
Since an IPS is a large scale power system containing a large number of high frequency power switches and other components that demand great resources from a simulator, it is not practical to simulate using traditional offline simulation tools. A Ship Dynamic Model that determines the load torque to the electric propulsion motor, and which calculates ship speed and propeller speed according to hydrodynamics. After preliminary testing, the modules were integrated and distributed across the eMEGAsim simulator’s CPUs.
Preliminary simulation results published in a technical paper presented by the University of Michigan team at the IEEE Electric Ship Technologies Symposium have verified that the Opal-RT simulator is capable of performing simulations for a variety of scenarios including failure emulation, power flow path reconfiguration and energy management. When the main neutral becomes open at some place (blue explosion, at left in diagram), the ground rods will try to give an alternate path for 120-volt circuits through the earth, but inadequately. So to a large degree the system of circuits is subject to 240 volts, which, depending on what is turned on out on the circuits, tries to run things by using the neutral bar as its path between its two hot main wires. Whenever a main hot becomes open somewhere (blue explosion in the right-hand diagram), the system of circuits is effectively disabled in all its 240-volt circuits and in half its 120-volt circuits (the red ones above). In my experience it is more common for a main open neutral (or hot) to occur along the power company's lines and connections than in the panel or main breaker of a home as I have depicted above. The following reference material is reprinted, with permission, from the Engineer's Relay Handbook, 5th edition, published by the Relay and Switch Industry Association (RSIA) – formerly NARM. This section covers definitions, terminology, and symbols of relays for general switching purposes, military applications, electronic circuits, and airborne and space-age equipment. There is a sequence of events in relay pick up (operate) and dropout(release) with respect to current rise and decay. In Table 1.3 preferred and non-preferred terms relating to relay performance are summarized.
The contact switching combinations available on a relay are defined in terms of number of poles, number of throws(single or double), normal position(open or closed contacts),and the sequence to make and break.
The combination in which the contacts are closed in the de-energized or unoperated position is designated normally closed (NC).
Example: SPST NO DM refers to single pole, single throw, normally open, double make contacts. In accordance with American National Standards Institute Y32.2-1975, the following letter symbols may be used with any relay symbols to show the special features a relay possesses. The term "slow" and "fast" are relative, and the degree of rapidity is not to be implied by the use of the symbol on a relay. The proper polarization for a polarized relay is shown by the use of plus (+) and (-) designations applied to the winding leads. The following definitions do not include terms peculiar to mathematical formula, statistical analysis, relay reliability studies, and the like. Capacitance CISO The maximum allowable capacitive coupling between two specified test points. Closed value, measured As the current or voltage on an unoperated latching relay is step applied the lowest value at which all contact function. Closed value, specified As the current or voltage on an unoperated latching relay is step applied the value at or below which all contact must function. Coil An assembly consisting of one or more windings, usually wound over over an unsulated iron core on a bobbin or spool. Contact follow.The further specified movement of the contact tips (points) when making and after they have just touched and while they are traveling in the same direction as that of the moving contact member. Contact gap.The gap between the contact tips (points) under specified conditions, when the contact circuit is open.
Contact, stationary A member of a contact combination that is not moved directly by the actuating system. Current, minimum load.ITMIN(rms)-The minimum current required to maintain the relay in the on-state (nominal load voltage applies). The following definitions do not include terms peculiar to mathematical formulae, statistical analysis, relay reliability studies, and the like. But when I followed the directions (connect the switch's white wire to neutral, red wire to load, black wire to line), it didn't work.
The results: 124 volts across the load and line, but 0 volts across either load or line and neutral and 0 volts across either load or line and ground. Before doing that, I thought I'd get the advice of my favorite batch of experts here at the Dope. That device assumes that the power feed is coming in from the top of the box and the wire to the light goes out through the bottom. The electrician is supposed to wrap black electrical tape around the white wire to show that it's not being used as a neutral in that case, but I've seen a lot of examples where the wires weren't marked to code.
If you get 120 volts there then they simply have the hot and neutral reversed somewhere on the circuit (not all that uncommon of a mistake). If you have missing grounds it's still a problem, though not quite as bad, and either way it's not to code. I'd like to come out and take a look at your house some night after work, but I can't do it any time in the next week or so. Also in the box, connected to each other but to nothing else, are two white wires, which I assumed were neutral. I believe it is another SPST, with two separate black wires, but I won't swear to that until I check again. The black wire of each pair is connected to one side of the non-working switch, and the whites are tied to each other. But this and other attempts to hook them up seem to indicate that this house's ancient wiring won't support them.
His local government killed him, ostensibly to protect him from his gambling habit.Several months earlier at a local bar, Fairfax County, Virginia, detective David Baucum overheard the thirty-eight-year-old optometrist and some friends wagering on a college football game. IPS consists of an architecture, family of modules, and design process which enable the development of affordable propulsion and electrical systems that can be configured for a broad range of naval applications including surface combatants, aircraft carriers, amphibious ships, auxiliary ships, sea lift ships and high value commercial ships. Unlike a conventional radial electrical distribution system which distributes power to loads through load centers, ZEDS employs two main buses (starboard bus and port bus) to provide redundant power flow paths for vital loads.
The main objective of real-time power management is to ensure continuous power supply for electric loads, thereby augmenting the reliability and survivability of the shipboard Power System, and consequently enhancing the mission effectiveness of the warship. Jing Sun at the University of Michigan’s Department of Naval Architecture and Marine Engineering has developed, with financial support from the US Office of Naval Research (ONR), a PC-based Real-Time Simulation facility for conducting All Electric Ship IPS analysis and optimization. Sun and her team is designed to address the multi-disciplinary issues associated with All Electric Ships, such as optimal power management and dynamic system reconfiguration.
Opal-RT has continued to further enhance the eMEGAsim simulation platform for AES applications. The eMEGAsim simulator used at the University of Michigan is equipped with 8 INTEL CPUs allocated in 4 physically separate targets. Real-time simulation not only provides greater simulation speed, but also provides Hardware-in-the-Loop testing and rapid prototyping capabilities that are unmatched by offline simulation tools. Since a DC zonal architecture has many advantages over an AC zonal architecture for AES applications, the research team elected to adopt a DC zonal architecture.
The Gas Turbine, Fuel Cell and Electric Propulsion Modules were each assigned to one CPU on the simulator, while the ZEDS was separated into two subsystems and distributed across two CPUs. For the effects of an open neutral on two circuits that share their neutral, go to Shared neutral.
Although 240 volts is more powerful, the resistances it goes through in one of its sides (black, for instance) are in series with the ones it goes through in the other (red). However, these disabled circuits can conspire to run themselves weakly, using the good main hot (black above) as follows.


Therefore, if your home's electrical symptoms correspond to either type of main open described here, I generally recommend calling the power company first. They are also somewhat isolated from one another with respect to having a common relay language.
Certain specialized forms of relays have their own set of standards and may be designated by other terms.
The events are defined in terms of duration of coil current, armature motion, and contact actuation. The various combinations have been given form letter symbols in Figure 1.6 to simplify overall identification. The term single pole (SP) contact denotes that all contacts in the arrangement connect in one position or another to a common contact. Single throw (ST) contact combinations have a pair of contacts open in one relay position and closed in the other. The combination in which the contacts are open in the normal or nonoperated condition of the relay is designated normally open (NO). These contact combination have two independent contacts both connected to a third contact in one position of the relay.
When abbreviations are used to designate a contact assembly, the following order is used: (1) Poles (2) Throws (3) Normal position (4) Double make or break (if applicable). 1.6 Symbols for Relay Contact Combinations established by the American National Standards Institute (ANSI).

I think this room's wiring is somewhat more modern (not all of the outlets in the house have a neutral wire) it's a still a little funky. With the introduction of Power Electronic Building Blocks (PEBB), ZEDS can seamlessly and dynamically reconfigure power flow paths in response to different load priorities for different real time battle scenarios.
Sun has been involved in a number of research projects related to control system development and optimization of automotive and marine propulsion systems with a particular focus on system modeling, identification, control algorithm development and integration, control system rapid prototyping and experimental validation. In parallel with development of the simulation facility, a modularized IPS model has been developed and integrated into the simulator. In addition to incorporating the latest i7 multi-core CPU technology from INTEL, Opal-RT simulators now come equipped with Dolphin DX PCI-Express communications technology, which has shown outstanding results for low to medium size bandwidth communication. The facility has been used in several ongoing projects, including an ONR-supported project on dynamic reconfiguration control for IPS in AES energy management.
To compare the abnormal conditions shown below with diagrams of normality, view these diagrams of: Your system, Power company, Main panel, Weak points, and Circuit flow. The common result is that some lights in the home will burn dimmer than usual and others brighter, that this can be affected by other things in the home going on or off, and that bulbs can blow out and electronics can be damaged.
Any 240-volt circuit that is ready to run (is "on") will take advantage of its connection with both good and bad hots and of the fact that bad-hot 120-volt circuits have a neutral connection. These did not kill power to all circuits when they were turned off, but only to most 120-volt circuits in the same panel.
In the case of an open main hot, reasons not to call them would be any indications that the problem is likely inside the home. Over the years, each company , by usage and practice, has tended to establish differing designations for identical or similar relay items. For a discussion of relays associated with electric power apparatus see Relays and Relay Systems Associated with Electric Power Apparatus, C37.90-1971 of the American National Standards Institute.
A double pole (DP) contact consists of two single-pole contact arrangements actuated by the same mechanical system and operation concurrently.
They are designated double make (DM) when normally open and double break (DB) when normally closed.
The device is connected in series with the main contactor coil of the starter and the opening or closing of the pilot device directly controls the de-energizing or energizing of the starter. When cross-references are made, the preferred terminology is the one under which the definition appears. On ac, the rms current value is generally used in the product of current and turns and is referred to as rms ampereturns. Also, the simultaneous closure of the contacts of a continuity transfer or bridging contact combination. If there is no actual opening but only a change in resistance, it is referred to as dynamic resistance. This provides two contact air gaps in series when the contact is open (see V or Y contact combination in Figure 1.6 ). The passing may occur either when the relay picks up or when the relay drops out or both during picking-up and dropping out.
It is floating in a non-contacting position prior to bounce and after energizing or de-energizing the coil. In solid-state relays, it is the current that flows through the load when the relay is in the off-state. Relay control may be lost during and following the surge until the junction temperature falls below the maximum rated temperature. With respect to an operating coil winding, use of the word commonly assumes enough power to operate the fully unless otherwise stated. For a measuring relay: An energizing quantity which either by itself constitutes the characteristic quantity or helps to constitute it.
From your description, it sounds like you have a lot more going on than just a weird switch. In addition, the system has also been integrated with programmable power supplies, programmable electrical loads, energy storage banks, and power electronics to form a hybrid power system test-bed, using the Opal-RT simulators as the core components. If the five resistances shown in the left diagram are 60 watt bulbs, they normally each burn at a 60-watt level and use 300 watts together. In the diagram above, good black hotness will find its way through the 4500-watt water heater and from there through its red breaker and a red lighting (120-volt) breaker and its three bulbs to good neutral.
Where this sort of arrangement (a "split-bus" panel) still exists, an extensive outage or flickering in the house can be due to a tripping or a half-compromised connection at this sub-main. For instance, if there are main or submain fuses and they have not been checked, or if some 240-volt appliance still operates completely properly (a 240-volt dryer must heat up, not just turn its drum). The desirability for a standardization of relay terms, definitions and symbols is thus apparent.
The final actuation time exceeds the initial actuation time by the amount of the contact bounce. The common one is in contact with the second, but not with the third, in one position of the relay, and reverse this connection in the other relay, and reverses this connection in the other relay position. Note: CT indicates continuity transfer, one asterisk denote Make-Before-Break, and two asterisks denote Break-Make-Before-Break. Does not apply to electromechanical relays where contacts are open and current cannot flow.
Likewise between either of the black wires and the box itself, which has a ground wire, was 0 volts.
After overhearing the men wagering, Baucum befriended Culosi as a cover to begin investigating him.
The 120-volt-powered current going on this strange path will run the water heater at 29 watts and each 60-watt light bulb at 39 watts, for total of 146 watts. When a sub-main has connection trouble internally (or one blown sub-main fuse) or with its busbar or with one of its wires that feeds to half of its 120-volt circuits, then the scenario described above regarding a "main open hot" can show itself, but only if there is a 240-volt circuit among those fed from the sub-main. The starter drops out in the event of a power failure but picks up or recloses automatically when the power is restored, (b) In three wire control the main contactor coil of the starter is wired in series with its own NO auxiliary contacts. During the next several months, he talked Culosi into raising the stakes of what Culosi thought were just more fun wagers between friends to make watching sports more interesting. This feature makes it possible for the system to implement physical components for Hardware-in-the-Loop simulation or to perform fast control prototyping experiments. A sub-main problem can be confirmed by testing whether more than one 120-volt circuit in the panel is dead while each main service wire entering the panel from outdoors still shows good hotness to ground. IEC has Technical Committee 41 on all types of relays and publication 50 (446) is a chapter of definitions on electrical relays.
On break-make contacts, the time interval between initial opening of the normally closed contact and closure of the normally open contact is called transfer time.
The "Start-Stop" push-button station, which requires the use of three wires between the control and the starter, is connected in parallel with the coil. In addition, the synchronized targets can run Real-Time Simulation at different time steps, providing the flexibility to distribute complex models across multiple targets or CPUs within the simulation platform. The result of this kind of condition is that a water heater automatically turning on or a person turning an electric oven on will make dead lights run dimly, and the lights will go back off when the 240-volt item turns off. Dropout (Figure 1.2) On de-energization of the coil, the magnetic flux does not die out immediately. In the event of a power failure, the starter will drop out and remain de-energized until the "Start" button is depressed.
Under Virginia law, that was enough for police to charge Culosi with running a gambling operation. The eMEGAsim Real-Time Simulator can also interact with other standalone Opal-RT targets via an Ethernet link.
However, if a set of breakers is located in a separate subpanel fed from the main panel, then the symptoms of either type of main open will be possible). The length of time it persists depends upon the release characteristics of the coil (fast-to-release, slow-to-release, and the like).
Since the starter drops out when there is a power failure and will not pick up or reclose again until the start button is depressed, this Control system provides low voltage protection.
And that’s when they brought in the SWAT team.On the night of January 24, 2006, Baucum called Culosi and arranged a time to drop by to collect his winnings. Standalone targets can be used as experiment data acquisition devices or as any simulated AES subsystem. When Culosi, barefoot and clad in a T-shirt and jeans, stepped out of his house to meet the man he thought was a friend, the SWAT team began to move in. It will be seen that a normally open contact may be momentarily reclosed as a result of armature rebound off the backstop. That same year, Virginia’s government spent $20 million promoting the state lottery.The raid on Sal Culosi was merely another red flag indicating yet more SWAT team mission creep in America.
It wasn’t even the first time a Virginia SWAT team had killed someone during a gambling raid.
Police said they approached the tinted car where Reed was working security, knocked, and identified themselves, then shot Reed when he refused to drop his handgun.
