I would like to run 3 separate 120 volt items 10.2 max amp per item using 3 separate circuits, but only have a single switch box to use. I have seen single circuit in 3 switch out, but want 3 in 3 out. Does anyone make this?

  • With a quick search, I haven't found any yet. I have found an interesting 2 in, 3 out It has 2 switches on top which use one common hot and a 3rd switch on the bottom which uses another hot (and which can also be a 3-way switch). But I haven't yet found a true 3/3, which you need to get 10A per switch. Apr 10, 2019 at 18:25
  • You might be able to use a single switch to control three relays.

  • Feels like that might be too many wires for the box... that's a total of 6 14/3 cables coming into one single switch box? Maybe I misunderstand what you're asking tho...

  • @JPhi1618 6 14/2. Apr 10, 2019 at 18:40

    If they're all switch loops, you could get away with 3 14/3s, but I also didn't find any when searching.

Yes, Pass & Seymour Despard should git-r-dun.

You have a much bigger problem though. That's an awful lot of wires.

Assuming you have 3 supply cables and 3 onward cables, all /2, that means 12 conductors. +2 for the yoke, +1 for all grounds, and +1 for all cable clamps, totals 16 conductor units.

With #14 wire that will be 32 cubic inches. With #12 wire that will be 36 cubic inches.

A single box is about 10-12ci, so that ain't gonna happen. A 4x4 2-gang box is 22 ci, and normal drywall 1-gang mud rings don't add enough cubes to save you. They do make 10.2 ci. mud rings, but those won't work with drywall.

You are better off going to a 4-11/16" square box which 42 cubic inches depending on depth. That with a 1-gang mud ring will suffice.

Now if you use all switch loops, you have 9 conductors, so with yoke+ground+clamps that is 13 wire counts. with the yoke+ground+clamps. That's 26 c.i. For #14 wire and 29.25 c.i. with #12. That might barely scootch under with a 4x4 box and a 1-gang mud ring if #14.
