I recently purchased 3-8' H0 fluorescent strip lights and want to hook them up to one switch. 3 - Can I match the wire diameter and type that is supplied with the light throughout the system?
What I have so far is 12g wire to the first box I tapped into, and ran 14g to the first light light. Any wire you run between fixtures needs to be the same size as your initial run, and sized according to the breaker used.
The fixture is a very short run of equipment wire in a controlled environment, with a known load (only the maximum rating of the bulbs.) So it is up to the manufacturer to properly size the wire. The feed needs to be sized knowing that at any point, it could be shorted, added on to or otherwise modified, be in adverse conditions such as insulation with poor heat dissipation, etc. You are correct in that NEC allows mixed wire sizes as you described; however I warn against it for the simple reason if it's to be inspected, it may not pass. Inside the light fixture itself I have 12g wire going to the light attached to the 20g factory wires inside the light. So now I have a total of 6-75 watt standard light bulbs and two 8-strip lights for a total of 930 watts max draw on this circuit. As mentioned, you could also do this connection in a separate box outside the fixture and run a leg to inside the fixture. So if I am understanding this correctly, there should only be one set of wires entering this fixture. I can however install a receptacle box next to the fixture (or between the two fixtures somewhere) and pigtail over to each light. EXCEPTION: Within employee work areas, clearances on common use circulation paths shall be permitted to be decreased by work area equipment provided that the decrease is essential to the function of the work being performed.
EXCEPTION: The clear width shall be permitted to be reduced to 32 inches (815 mm) minimum for a length of 24 inches (610 mm) maximum provided that reduced width segments are separated by segments that are 48 inches (1220 mm) long minimum and 36 inches (915 mm) wide minimum. EXCEPTION: Entry doors to hospital patient rooms shall not be required to provide the clearance beyond the latch side of the door.
These forces do not apply to the force required to retract latch bolts or disengage other devices that hold the door or gate in a closed position. EXCEPTION: In assembly areas, aisle ramps adjacent to seating and not serving elements required to be on an accessible route shall not be required to comply with 405. EXCEPTION: Within employee work areas, the required clear width of ramps that are a part of common use circulation paths shall be permitted to be decreased by work area equipment provided that the decrease is essential to the function of the work being performed. EXCEPTION: Within employee work areas, handrails shall not be required where ramps that are part of common use circulation paths are designed to permit the installation of handrails complying with 505. EXCEPTION: Existing call buttons and existing keypads shall be permitted to be located at 54 inches (1370 mm) maximum above the finish floor, measured to the centerline of the highest operable part. 60 inches (1525 mm) - Other car configurations that provide a turning space complying with 304 with the door closed shall be permitted.
EXCEPTION: Where space on an existing car operating panel precludes tactile markings to the left of the controls, markings shall be placed as near to the control as possible.
EXCEPTION: In elevator cars with more than one opening, hoistway doors and gates shall be permitted to be of the manual-open, self-close type. The ADA and other Federal civil rights laws require that accessible features be maintained in working order so that they are accessible to and usable by those people they are intended to benefit. EXCEPTION: Platform lifts serving two landings maximum and having doors or gates on opposite sides shall be permitted to have self-closing manual doors or gates.
The one thing that inspectors never fail to check is the required emergency-egress window from a sleeping room. Even the most energy-efficient windows and doors must be installed properly, by professionals, and according to manufacturing recommendations.
Improper installation will reduce energy performance and create energy leaks that result in higher energy bills, and may even cause moisture damage to structure, interior applications such as drywall and flooring, as well as damage to insulation materials and finally deterioration of exterior applications such as stucco or sidings. The following additional guidelines should help the homeowner in the process of selecting a knowledgeable and experienced installer as well as to verify proper installation during the project.

Ie, I have the most convenient location for the switch and origination of the wiring in the general location of the first light. So if the first part of the run is #12 and then you switch to #14 for the remainder of the circuit then the breaker needs to be 15A.
Tapped into my nearest receptacle (an existing box that fed the lighting circuit) using 12 g wire to the first light. I believe the code allows for a hardwired extension cord or one plugged into a receptacle within 6 feet. I can go into it (obviously), but under no circumstances can another set of wires come out of it. I did not nor did anyone else say only one pair of wires (with ground) could enter the fixture housing. The provisions of Chapter 4 shall apply where required by Chapter 2 or where referenced by a requirement in this document. Where the accessible route makes a 180 degree turn around an element which is less than 48 inches (1220 mm) wide, clear width shall be 42 inches (1065 mm) minimum approaching the turn, 48 inches (1220 mm) minimum at the turn and 42 inches (1065 mm) minimum leaving the turn. An accessible route with a clear width less than 60 inches (1525 mm) shall provide passing spaces at intervals of 200 feet (61 m) maximum. Where handrails are provided along walking surfaces with running slopes not steeper than 1:20 they shall comply with 505. Security personnel must have sole control of doors that are eligible for the Exception at 404.1. Manual doors and doorways and manual gates intended for user passage shall comply with 404.2. Door closers and door stops shall be permitted to be 78 inches (1980 mm) minimum above the finish floor or ground. Maneuvering clearances for forward approach shall be provided when any obstruction within 18 inches (455 mm) of the latch side of a doorway projects more than 8 inches (205 mm) beyond the face of the door, measured perpendicular to the face of the door or gate.
A door can be recessed due to wall thickness or because of the placement of casework and other fixed elements adjacent to the doorway. The distance between two hinged or pivoted doors in series and gates in series shall be 48 inches (1220 mm) minimum plus the width of doors or gates swinging into the space.
Handles, pulls, latches, locks, and other operable parts on doors and gates shall comply with 309.4. Existing locks shall be permitted in any location at existing glazed doors without stiles, existing overhead rolling doors or grilles, and similar existing doors or grilles that are designed with locks that are activated only at the top or bottom rail.
Access gates in barrier walls and fences protecting pools, spas, and hot tubs shall be permitted to have operable parts of the release of latch on self-latching devices at 54 inches (1370 mm) maximum above the finish floor or ground provided the self-latching devices are not also self-locking devices and operated by means of a key, electronic opener, or integral combination lock. Door hardware that can be operated with a closed fist or a loose grip accommodates the greatest range of users. Door closers and gate closers shall be adjusted so that from an open position of 90 degrees, the time required to move the door to a position of 12 degrees from the latch is 5 seconds minimum. Door and gate spring hinges shall be adjusted so that from the open position of 70 degrees, the door or gate shall move to the closed position in 1.5 seconds minimum.
Fire doors shall have a minimum opening force allowable by the appropriate administrative authority. The maximum force pertains to the continuous application of force necessary to fully open a door, not the initial force needed to overcome the inertia of the door. Swinging door and gate surfaces within 10 inches (255 mm) of the finish floor or ground measured vertically shall have a smooth surface on the push side extending the full width of the door or gate. Tempered glass doors without stiles and having a bottom rail or shoe with the top leading edge tapered at 60 degrees minimum from the horizontal shall not be required to meet the 10 inch (255 mm) bottom smooth surface height requirement.

Doors, gates, and side lights adjacent to doors or gates, containing one or more glazing panels that permit viewing through the panels shall have the bottom of at least one glazed panel located 43 inches (1090 mm) maximum above the finish floor. Doorways shall provide a clear opening of 32 inches (815 mm) minimum in power-on and power-off mode. Where doors and gates without standby power are a part of a means of egress, the clear break out opening at swinging or sliding doors and gates shall be 32 inches (815 mm) minimum when operated in emergency mode. The clear width of a ramp run and, where handrails are provided, the clear width between handrails shall be 36 inches (915 mm) minimum. Ramps that do not have level landings at changes in direction can create a compound slope that will not meet the requirements of this document. The landing clear width shall be at least as wide as the widest ramp run leading to the landing. Ramps that change direction between runs at landings shall have a clear landing 60 inches (1525 mm) minimum by 60 inches (1525 mm) minimum. Ramp runs with a rise greater than 6 inches (150 mm) shall have handrails complying with 505. Ramps not subject to the exception to 405.5 shall be designed to maintain a 36 inch (915 mm) minimum clear width when handrails are installed.
Edge protection shall not be required on ramps that are not required to have handrails and have sides complying with 406.3. Edge protection shall not be required on the sides of ramp landings serving an adjoining ramp run or stairway.
Edge protection shall not be required on the sides of ramp landings having a vertical drop-off of A? inch (13 mm) maximum within 10 inches (255 mm) horizontally of the minimum landing area specified in 405.7.
The floor or ground surface of the ramp run or landing shall extend 12 inches (305 mm) minimum beyond the inside face of a handrail complying with 505. The extended surface prevents wheelchair casters and crutch tips from slipping off the ramp surface. A curb or barrier shall be provided that prevents the passage of a 4 inch (100 mm) diameter sphere, where any portion of the sphere is within 4 inches (100 mm) of the finish floor or ground surface. Counter slopes of adjoining gutters and road surfaces immediately adjacent to the curb ramp shall not be steeper than 1:20. Curb ramps and the flared sides of curb ramps shall be located so that they do not project into vehicular traffic lanes, parking spaces, or parking access aisles. Diagonal or corner type curb ramps with returned curbs or other well-defined edges shall have the edges parallel to the direction of pedestrian flow.
Raised islands in crossings shall be cut through level with the street or have curb ramps at both sides.
Call buttons and keypads shall be located within one of the reach ranges specified in 308, measured to the centerline of the highest operable part. The clear floor or ground space required at elevator call buttons must remain free of obstructions including ashtrays, plants, and other decorative elements that prevent wheelchair users and others from reaching the call buttons.
The call button that designates the up direction shall be located above the call button that designates the down direction. A destination-oriented elevatorA system provides lobby controls enabling passengers to select floor stops, lobby indicators designating which elevator to use, and a car indicator designating the floors at which the car will stop.
Call buttons shall have visible signals to indicate when each call is registered and when each call is answered.
A visible and audible signal shall be provided at each hoistway entrance to indicate which car is answering a call and the car's direction of travel. In existing elevators, a signal indicating the direction of car travel shall not be required. Visible signal fixtures shall be centered at 72 inches (1830 mm) minimum above the finish floor or ground. Destination-oriented elevatorsA shall be permitted to have signals visible from the floor area adjacent to the hoistway entrance. Audible signals shall sound once for the up direction and twice for the down direction, or shall have verbal annunciators that indicate the direction of elevator car travel.
Existing elevators shall not be required to comply with the requirements for frequency and dB range of audible signals.
Each destination-oriented elevatorA in a bank of elevators shall have audible and visible means for differentiation.
Destination-oriented elevatorsA shall provide tactile car identification complying with 703.2 on both jambs of the hoistway immediately below the floor designation. The device shall be activated by sensing an obstruction passing through the opening at 5 inches (125 mm) nominal and 29 inches (735 mm) nominal above the finish floor. The device shall not require physical contact to be activated, although contact is permitted to occur before the door reverses.
For cars with in-car lanterns, T shall be permitted to begin when the signal is visible from the point 60 inches (1525 mm) directly in front of the farthest hall call button and the audible signal is sounded. The level of illumination at the car controls, platform, car threshold and car landing sill shall be 5 foot candles (54 lux) minimum.
Where the elevator panel serves more than 16 openings and a parallel approach is provided, buttons with floor designations shall be permitted to be 54 inches (1370 mm) maximum above the finish floor. In existing elevators, car control buttons with floor designations shall be permitted to be located 54 inches (1370 mm) maximum above the finish floor where a parallel approach is provided. Emergency control buttons shall have their centerlines 35 inches (890 mm) minimum above the finish floor. Emergency controls, including the emergency alarm, shall be grouped at the bottom of the panel.
Raised character and braille designations shall be placed immediately to the left of the control button to which the designations apply.
Buttons with floor designations shall be provided with visible indicators to show that a call has been registered. Keypads shall be identified by characters complying with 703.5 and shall be centered on the corresponding keypad button. As the car passes a floor and when a car stops at a floor served by the elevator, the corresponding character shall illuminate.
In destination-oriented elevators, a display shall be provided in the car with visible indicators to show car destinations.
The signal shall be an automatic verbal annunciator which announces the floor at which the car is about to stop. The verbal annunciator shall be 10 dB minimum above ambient, but shall not exceed 80 dB, measured at the annunciator. Elevator cars shall provide a clear width 42 inches (1065 mm) minimum and a clear depth 54 inches (1370 mm) minimum.
Cars that provide a clear width 51 inches (1295 mm) minimum shall be permitted to provide a clear depth 51 inches (1295 mm) minimum provided that car doors provide a clear opening 36 inches (915 mm) wide minimum. Existing elevator cars shall be permitted to provide a clear width 36 inches (915 mm) minimum, clear depth 54 inches (1370 mm) minimum, and a net clear platform area 15 square feet (1.4 mA?) minimum.
Elevator cars shall provide a clear floor space of 36 inches (915 mm) minimum by 48 inches (1220 mm) minimum and shall comply with 305.
If the telephone or device is in a closed compartment, the compartment door hardware shall comply with 309.
Inclined stairway chairlifts and inclined and vertical platform lifts are available for short-distance vertical transportation. Building owners are reminded that the ASME A18 Safety Standard for Platform Lifts and Stairway Chairlifts requires routine maintenance and inspections. The clearance between the platform sill and the edge of any runway landing shall be 1 inch (32 mm) maximum. A low-e coating is a thin, nearly invisible metallic coating on glass that lowers the emissivity of the glass.

That fixture wire is also high temp rated to operate next to the ballast, so your wire should be high temp also.
No weight is allowed on the extension cord unless the cord and connections are specifically designed to carry the weight of the fixture.
Weather you are joining them inside the fixture or in the separate box, the end result is still exactly the same. For example, if you have a finished ceiling and surface mount fixtures, you cannot run Romex cable on the surface from one fixture to the next. The others in line would have a 2nd house cable either in the same connector, of if more convenient, out of the other end and 3 wires in each nut. All components of an accessible route shall comply with the applicable requirements of Chapter 4. It would not be acceptable for security personnel to operate the doors for people with disabilities while allowing others to have independent access.
Clear openings of doorways with swinging doors shall be measured between the face of the door and the stop, with the door open 90 degrees. Maneuvering clearances shall extend the full width of the doorway and the required latch side or hinge side clearance. Operable parts of such hardware shall be 34 inches (865 mm) minimum and 48 inches (1220 mm) maximum above the finish floor or ground.
Hardware that requires simultaneous hand and finger movements require greater dexterity and coordination, and is not recommended. It does not apply to the force required to retract bolts or to disengage other devices used to keep the door in a closed position. The minimum clear width for automatic door systems in a doorway shall be based on the clear opening provided by all leaves in the open position.
The clear floor space adjacent to the control shall be located beyond the arc of the door swing. Changes in level other than the running slope and cross slope are not permitted on ramp runs.
The adjacent surfaces at transitions at curb ramps to walks, gutters, and streets shall be at the same level.
Curb ramps at marked crossings shall be wholly contained within the markings, excluding any flared sides. The bottom of diagonal curb ramps shall have a clear space 48 inches (1220 mm) minimum outside active traffic lanes of the roadway.
Each curb ramp shall have a level area 48 inches (1220 mm) long minimum by 36 inches (915 mm) wide minimum at the top of the curb ramp in the part of the island intersected by the crossings.
Building owners should note that the ASME Safety Code for Elevators and Escalators requires routine maintenance and inspections. The height of the clear floor or ground space is considered to be a volume from the floor to 80 inches (2030 mm) above the floor. Responding cars are programmed for maximum efficiency by reducing the number of stops any passenger experiences. Where in-car signals are provided, they shall be visible from the floor area adjacent to the hall call buttons. Tactile symbols and characters shall be provided adjacent to the device and shall comply with 703.2. Car doors shall be positioned at the narrow ends of cars and shall provide 32 inches (815 mm) minimum clear width.
Platform lifts shall not be attendant-operated and shall provide unassisted entry and exit from the lift. Because an accessible route requires an 80 inch (2030 mm) vertical clearance, care should be taken in selecting lifts as they may not be equally suitable for use by people using wheelchairs and people standing. Isolated or temporary interruptions in service due to maintenance or repairs may be unavoidable; however, failure to take prompt action to effect repairs could constitute a violation of Federal laws and these requirements. My plan is to simply tap into the first light and run to the second and repeat to the 3rd light. I can easily cut it and attach bigger wire but this doesn't make sense when you compare to the existing wire supplied by the factory. You could also use MC from the remote box to the fixture and for that I don't know the sizing code. Therefore, you can go from one end of a fixture to another and pigtail the switched power to the ballast black the black, white to white and with the grounds attached to the frame. Openings more than 24 inches (610 mm) deep shall provide a clear opening of 36 inches (915 mm) minimum. Where sliding doors are in the fully open position, operating hardware shall be exposed and usable from both sides. Curvilinear ramps with small radii also can create compound cross slopes and cannot, by their nature, meet the requirements for accessible routes.
The landing clear width shall be at least as wide as the curb ramp, excluding flared sides, leading to the landing. Diagonal curb ramps provided at marked crossings shall provide the 48 inches (1220 mm) minimum clear space within the markings.
Each 48 inch (1220 mm) minimum by 36 inch (915 mm) minimum area shall be oriented so that the 48 inch (1220 mm) minimum length is in the direction of the running slope of the curb ramp it serves. Recessed ashtrays should not be placed near elevator call buttons so that persons who are blind or visually impaired do not inadvertently contact them or their contents as they reach for the call buttons.
If a lift does not provide 80 inch (2030 mm) vertical clearance, it cannot be considered part of an accessible route in new construction. If you have any problems with the registration process or your account login, please contact contact us.
I think a 10 amp would have sufficed and am considering changing out the 20 amp breaker for a 10 amp. There shall be no projections into the required clear opening width lower than 34 inches (865 mm) above the finish floor or ground.
A level landing is needed at the accessible door to permit maneuvering and simultaneously door operation.
Diagonal curb ramps with flared sides shall have a segment of curb 24 inches (610 mm) long minimum located on each side of the curb ramp and within the marked crossing. The 48 inch (1220 mm) minimum by 36 inch (915 mm) minimum areas and the accessible route shall be permitted to overlap.
The audible signal and verbal annunciator shall be 10 dB minimum above ambient, but shall not exceed 80 dB, measured at the hall call button. Your 12 ga is not interrupted, it's a continuous circuit pigtailed at each device and run to the next until termination.
I think the point is to NOT have the 3 wires (or 6 depending on your perspective) ganged inside the fixture. Projections into the clear opening width between 34 inches (865 mm) and 80 inches (2030 mm) above the finish floor or ground shall not exceed 4 inches (100 mm). The wires inside the fixture to the ballast and from the ballast to the lamp sockets are not considered part of the circuit AFA the house wiring size and appropriate breaker size. It really is not possible to use the lighter gauge wires inside the fixtures as a bridge to the next fixture as there are only 2 leads inside many times long enough for a connection near either end of the fixture.
