2 circuits in one junction box Electrical - AC & DC - 2 circuits. 1 Junction box. OK? - Hello all. Is there any prohibition against power from two separate circuits entering one switchbox? Specifically, I want to have a switch that controls a dining room light to be in the same switchbox as a switch that controls a living room light. Power from Single-gang boxes typically use #8 screws, while double-gang boxes use #10 screws. Three-gang boxes and larger boxes may require #12 screws. It is important to use the correct size screws for the box, as using screws that are too small may not provide adequate support for the box and could lead to problems down the road.

After receiving a fun little shock, I found that someone was using 14/3 cabling to carry 2 different circuits to this 1 gang box (line on left, load on . Yes, you could combine two circuits in a 5 -gang box, but why? Not why "2 circuits", why "5 gang"? You can easily put 3 light switches, provided . Electrical - AC & DC - 2 circuits. 1 Junction box.

One box - two circuits? Hello, I am trying to install an overhead light fixture in a house that I bought with some partially finished rehab work. There is a ceiling junction box in one room with two sets of wires, each on a different breaker. One group has two white wires, one red, one black. The other has only one white and one black.
For instance, I have three 20amp circuits - Can I then run all three through one conduit with 3 hot and three neutral wires and one ground wire (tying it in to all NM at the junction)? My preference would be to run 2 conduits - One with the 20amp circuits, the other with the 15amp circuits, keeping in mind that one of the 15 amp circuits will .
Is it in the kitchen? there are many instances when you have more then 2 circuits in one box. for example if you have 3 sets of lights and each set requires dedicated circuit and all 3 switches are in the same box, you will have 3 breakers ( circuits going to the box ). although in multi wire systems ( black, red, white) code states that if both circuits are feeding one device on the . the other dual facing boxes are all inside individual apartments, like one receptacle inside bedroom 1 and one in bedroom 2. I would like to avoid having apartment A paying the electrical usage of apartment B's range hood, and I think the range hood (or possibly over the range microwave in the future) are supposed to be dedicated anyways. I figure one has to be a jumper to the outlet..WRONG. I take off the wire nut from the black wires and the thing sparks. It would appear that this outlet box was not only being used as an outlet box, with wires to 2 other outlets, but as a junction box for wires on a different circuit.
And either 2 pole breaker or 2 single pole breakers with a handle tie. You may also run 2 12/2 cables. In this case, do not connect neutrals together in the junction box. All ground wires get spliced. In this case, handle tie is not required. But, don't forget that you have to turn off 2 breakers to cut all power to the junction box.
That's correct. Just one circuit, but two different hot runs in the same junction box. So: hot from junction box to 3-way switch (12/3 to second switch and third wire to lights.) This third wire will come back through the junction box where the hot originated from, to power the light and the following lights. I think that answers it, but in a box, I have two cables that are carrying power in to the junction box from different circuit breakers (lights and receptacles are on different circuits, and they happen to meet in this box). I was just making sure that I could connect all the grounds from Circuit 1 and Circuit 2.
Second, is it OK for both circuits to share the same ground bus bar in the box? Oh one last question. If my circuits are correctly setup, meaning I have a 20A breaker for the mini split (requires 20A breaker) and a 15A breaker for the 15A outlet, with both using 12AWG wire, do I need to/should I use a fused disconnect box?
