Switch Wiring


I am 2 multi gang boxes away from rough in inspection and confirming I have this setup correct.

From left to right
The 1st wire is an outgoing wire for 2 lights above cabinets.
The 2nd wire is incoming power for the 1st set of wires
The 3rd wire is an incoming 3 way from the other switch location (the other switch is fed power from the circuit)
The 4th wire is an outgoing 14-2 wire for the 3 way lights

The 4 wires all share the same circuit thus I nutted all the grounds together except I did not nut the neutrals together. Should the white neutrals all be nutted?



Did I need to run the 2nd wire (incoming power for non 3 way light)? Could I have used the power from the incoming 3 way? I don't think so since I believe either back or red is hot???

The 5th and 6th wire all the way to the right is for a middle of run 20 amp receptacle and an end of run 20 amp receptacle. (obviously on its own circuit)

ALL grounds of all circuits should be tied together. IMO the description of the 3-way is inadequate to make an assessment.

Interesting, I didn't know all grounds should be tied together even if they are different guages and different circuits. I'll tie them together that being the case. Thinking about it and it does make sense.

Regarding the 3 way. There is another 3 way switch at the entrance of the room and the start of the run. The main circuit branch is tied into that room entrance box. From the entrance box a 14-3 cable is run to the box pictured above and tied to a 3 sway switch which will have a 14-2 going to the lights. Should the neutrals all be tied together?

Are you installing a 3-way switch in the box pictured??

your what i like to call a "super twister". nothing wrong with it, just harder to troubleshoot and bend the wires into the box when they're twisted up as far as they can go.

Not sure I completely understand your setup but by your question I assume that you have separate circuits in the box pictured and want to know if the neutrals can be tied together?

I'm new at so I can change I thought it looked cleaner so going forward I'll do it about half way.

Yes, 2 different circuits

The right 20 amp cable is on a 20 amp circuit. An outlet will be located there. Tough to see but there is another 20 amp cable in there going to another outlet.

The left 4 cables are for 2 light switches on a 15 amp circuit.
1st cable is an outgoing wire for 2 lights above cabinets.
2nd cable is incoming power
3rd cable is an incoming 3 way from the other switch location (the other switch is fed power from the circuit)
4th cable is an outgoing 14-2 wire for the 3 way lights

The neutrals on the 20 amp cable and 15 amp cable I don't believe should be tied together.

I'm curious if the neutrals on cable 1 and cable 2 (currently twisted) should be tied to neutrals on cable 3 and cable 4 (currently twisted)

Cables 1-4 share a 15 amp circuit
Cables 5 and 6 are 20 amp on a 20 amp circuit

Cables 1 thru 4 neutrals can be "twisted together"

Cables 5 and 6 can be "twisted together" but kept separate from cables 1 thru 4's neutrals.

If this was part of a MWBC(multi-wire branch circuit) all neutrals can be tied together. A handle-tie at the panel or other indication should indicate that the two breakers are part of a MWBC so both should be shut down when working on either circuit of a MWBC.

You do not want to share neutrals on different circuits because you could have the breaker going to cables 1 thru 4 off but current is still "traveling" on the neutral of cables 5 and 6 and could bite you.

I don't believe you could do that, the 3 way is fed from the other end, if he brought his feed from that same box, and you tied all the neutrals together, you would be creating a parallel connection with the neutrals, and a code violation of 310.4

The way the OP has them made up is correct.
