The switch wiring is all the same but the switch wire cable c leads up to a different set up. For this reason they are also known as travelers.

Light switch wire colours. In 220 volt circuits red wires are the secondary live wires. This color of wire is used to transfer power to switches and outlets in all types of circuits. In light switches ceiling roses junction boxes fand use boxes. Yellow and blue wires these wires usually come in pairs and pulled in conduits. Cable colours cables harmonised cable colours wire colours. White and gray wires are normally used as neutral conductors.
Looking for a 3 way switch wiring diagram. The neutral wire low potential is coloured blue used to be black. There is a chance that if your house has these old wiring colours the switch drops may be from a loop in loop out radial lighting circuit done with junction boxes rather than ceiling roses as shown in fig 2. Here are a few that may be of interest. Other color combinations including striped wiring may be used for other applications. A ground wire can.
The earth wire is striped green and yellow used to be only green. Saved by ruby allan. Blue wires are generally used in a three way and four way switch applications by travelers. Yellow and blue wires are sometimes used in more complicated circuits. What the individual electrical wire colors indicate green green with a yellow stripe and bare copper wires can only be used for grounding purposes. What the color of an electrical wire means black electrical wires.
The 2011 national electrical code required a neutral in. Blue and yellow. The bare earth wire in the cables above should be sheathed with a greenyellow earth sheathing wherever it is exposed eg. If they are they are used as hot wires to conduct current between switches and poles. Fan light switch light switch wiring wire switch light switches elegant ceiling fan unique ceiling fans home electrical wiring electrical installation. A simple standard electrical circuit has a black or red hot wire that carries power from the power source to the device eg switch fixture outlet appliance a white neutral wire that carries the power back to the power source and a green or bare copper ground wire that connects the device to the homes grounding system.
These are the most common colors used. They are used as hot wires and control electrical items like lights switched outlets and fans. The active wire high potential is coloured brown used to be red. Like black wires they can also be.
