From your diagram, it appears that you are tying the white wire and the bare wire together?
Hey, doing it yourself is great but if you are unsure of the advice given or the methods in which to job is done, don't do it.

This diagram is helpful but there is no explanation for the orange wire and why would the orange wire not go to the additional recepticles? Rewiring your house would have to be done by a trained, qualified electrician, who would then issue a certificate to the householder, and notify Building Control - they record the work and issue a Building Regulations Compliance Certificate.
When you constantly face problems with blowing fuses or tripping RCDs show that there is something wrong with the wiring. House wiring diagrams including floor plans as part of electrical project can be found at this part of our website. Many of us are wondering if the electrical wiring is safety in their homes, how good is the connections and how safety is a fuse box. Please note that it is expected that the person carrying out work in accordance with this guide will be competent to do so. As you can see all the installation is divided to 7 (can be more) different circuits to provide safely isolating the supply without the need of interrupting the supply to other circuits. In the example above we provided the most common home wiring diagram for 2 bedrooms flat, showing the wiring diagram for the lighting circuits on a different scheme for easy understanding of the routes of the cables through the property. 2 way switching means having two or more switches in different locations to control one lamp. Here we have a two way switching system that utilises two single gang two-way switches and a three wire control, shown in the new harmonised cable colours. Here we a have a schematic (Fig 1) which makes it easy to visualise how this circuit works. The schematic is nice and simple to visualise the principal of how a two way switch works but is little help when it coms to actually wiring this up in real life!!
Fig 2 below shows how we achieve this configuration. Just like any loop-in loop-out radial circuit, the switch cable from the ceiling rose contains two wires, a permanent live and a switched live. I may be getting this wrong but looks to me that the blue core on cable C and the black core on D would be permanent live. Hi, I’m adding another switch to the lighting circuit in my utility room and ive split what was a triple gang one way switch for lights, outside light and extractor fan to a one gang two way and a 2 gang one way.
Yes Michael – you just need to introduce intermediate switch into a two way switching setup (sometimes called three-way switching or two-way plus intermediate). I am replacing my switches one of my old switches has 4 cables and 4 connections however my new 1 gang 2 way switch only has 3 connections . So if I understand you correctly, this is not 2 way switching and both lights work but it is the switch position you wish to change. Hi, tried to replace my hall light which is operated by the switch in the hall only, but is a two way switch operating the landing light, which is a one way switch. I have 2 way switching in my bedroom, it seemed to work ok with standard filament bulbs but I have now swapped over to LED and have noticed a problem.
I have bought a single gang PIR to automatically turn on a hallway light but the light is also independently switched on and off in another switch behind it… The new PIR has a COM and L1 port and the existing has a wire in COM, L1 and L2… Can I assume L2 is rage communication between the second switch and therefore place the wire from COM to COM on the PIR and the wire from L1 to L1 on the PIR, can the L2 wire be left loose or could I add that to L1 on the PIR?
Sometime ago, thinking the upstairs hall light was off, I discoved the light bulb had a small glow.

Hi I have a new 2way light switch which does not have a com on it,how would I go about switching it over?.
I’m confused as to why they are identically wired and have a 3 and 4 core in both switches.
Earthing metal switch faceplates – your diagrams only suggest this for one of the switches; surely it should be for both!
There is a note on the diagram regarding earthing metal face plates and the earth loop shown on one of the switches illustrates this.
I ran a typical loop in loop out radial to each rose and brought the master (4 gang) strappers back individually from each of the single 2 way switches. I double checked my wiring and confirmed that each set of switches are wiring indentically, 3 wiring, 2 way arrangement. Hello, quick question, does the three core and earth loop in and out of multiple lights, reason I ask is I have 2 single gang 2 way lights switches and 3 lights, all the diagrams show is B to the next light but not the 2 way control? Two control a single (or multiple) light fixture with more than one switch, you need to use a three-way switch. Once you understand how three way switches work, it's fairly easy to figure out how to wire it.
There is two lights and i want to be able to turn them on by switch (or off) the convienient palce is the garage and i can snake it down the wall there. Based on your description in post #1 of light-switch-switch-light, the drawing in post #3 is the correct one. The black line to goes to other recepticles is always hot (notice it doesn’t go through the switch). Learning those pictures will help you better understand the basics of home wiring and could implement these principles in practise. Probably some of us would like to get some knowledge how to do the electrical wiring in the property before they contact an electrical company asking for the quote. On example shown you can find out the type of a cable used to supply a feed to every particular circuit in a home, the type and rating of circuit breakers - devices supposed to protect your installation from overload or short current. Make sure that each device used for isolating should be clearly identified which circuit it belongs to by durable labels fixed at the consumer unit.
The wiring diagram for the 3 bedroom flats or 5 bedroom houses will be slightly different due to the size of the property and quantity of sockets installed. They are wired so that operation of either switch will control the light. This arrangement is often found in stairways, with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.
It is possible to achieve a similar result using a two wire control which, although it saves on cable, is not recommended. In this state the lamp is off, changing the position of either switch will switch the live to the lamp turning it on. I’ve run 2 cables between the main and new utility light switches as per the diagram. The hall light works fine.but the outside light is on when the switch is in the off position and vice versa. When I took the old hall light down, the three red wires were joined together, the three earth wires joined together but only two of the three black wires were joined, one remained isolated.
If you’d mentioned this method of wiring I could have taken the faceplate off one of the switches before I spent an hour lifting flooring in the loft hunting for non-existent junction boxes.
The downstairs light is controlled by two switches, one at main door, the other(x) near the back of house.

Eventually the bulb blew, having replaced it, I now find the two switches don’t talk to each other. The radial covers 4 office rooms and required a single 2 way switch in each office and a master 4 gang switch by the main door. Upon performing a functional test, each set of switches worked fine until I got to the last set.
I need to put up security lighting on the outside of the home real soon, if fact I have the units. Straight accross the attic to the switches are about 25 feet from the first light, then light #2 is ten feet or so futher on. It is two lights being run by two separate switchs, the line in or power for both lights is coming from and through the first light, being that is closest to a source. The best sorce for power would be a new breaker at the panel from the East end and run all the way to the West end of the house about 45 feet all together. There is no way we can anticipate every situation and we do our best to inform of any risks for each job.
This means you can still have continueous power to recepticles and have a switched lighting cicuit.
Frankly speaking it is a good idea to get some basic information regarding rewiring in your home, what to ask electrician in his first visit and how dona€™t get them play a trick on you regarding the price. However, my Cable A (live supply) has always come directly into the original triple switch not to the first spot in the sequence. Attempted to put the new light up with all red wiring into the minibloc, all earth into the minibloc and all black into the minibloc, result- blown fuse. Managed to figure out how to control 3 lights in one room with intermediate switches on the desk and bedside lamp from your diagrams. By that I mean, one will switch on, but the other switch won’t turn it off and visa versa. The single 2 way switch did switch on the light and would only allow the 4 gang switch to operate if the L1 of the 2 gang switch was open.
I have bought a new touch switch that has only L1 and L2 which I would like to use upstairs, which is the switch with the two lives connected together L2 and the switch lives connected together out of L1. All of them are essentially doing the same thing, but it gets a little confusing when you switch the order of the devices. Obviously one shouldn’t work live anyway but the switched lives should be correctly sheathed. For cooker or inductive hobs use at least 6mm or 10mm cable depending on the consumption of the appliances and 10mm cable is to be used to supply the feed to electric shower. I’m thinking the Cable A brown is permanently live therefore should go into Main switch L1, is that correct, and, if so where can I connect the neutral??from your image, it looks like it should go somehow directly to the first spot, but running a cable to connect it is not really feasible without cutting into my newly plastered ceiling and walls. I also read that these need to be seperated by two switches because of some memory or auto feature?
