wiring 3 gang box with all three switches 2way


Hello, I'm roughing in a 3 gang box with 3 - 2 way switches. power is coming into one 3 gang boxes. Will pig tail 3 hot wires to the common terminals. in box one.

The return (white wire) will run to the other 3 gang box then connected to the return (white wire) of the three different lights.

Of course the Common terminal of the 3 switches will go to the hot side of each light.

Question: do I have to run 3 return wires from the original 3 gang (box 1) or can I run just one Return into box two and pig tail 3 return (white wires) to each of the 3 lights??

Help please

Re: wiring 3 gang box with all three switches 2way


Where are you located? Your question is not quite logical. In the US, a two pole switch is commonly referred to as a 3-way switch. I believe in EU and UK it is referred to as a 2-way switch. Two pole switches, regardless of what they are called always work in pairs.

The terminals of a two pole switch are referred to as travelers and the common. So are the conductors between a set of two pole switches.
When wiring a switch loop, that is when power (hot and neutral) is fed to the fixture, the hot which takes power to the switch location is referred to as the line conductor. The conductor which returns power from the switch to the fixture is referred to as the load conductor. That conductor could be referred to as a Return but that is not a common terminology.

Your use of the term Return is confusing.

You said that you were feeding power to the first 3 gang box. That means you are not wiring a switch loop. The first switch location is referred to as the line switch, the other (the 2nd) is referred to as the load switch.

Naturally you can connect incoming hot to the 3 line switches with pig tails. Power will travel through the switches to the load switches via the travelers of a 3-wire cable for each switch and return by the common.

Of course, you will need a hot and neutral (2-wire cable) from the line switch location to each fixture.

If you want to wire from the load (2nd) switch to each fixture, two conductors of the 3-wire cable between the switches would be travelers and the 3rd would be a neutral. Wire a 2-wire cable from the load switch location to each fixture.

Suggest that you tell us how you would like to wire these fixtures in more generic terms. Perhaps we can help.

One circuit only requires one neutral between the switch boxes.
