Electrician Explains Electrical Codes for Home Electrical Junction Boxes with Photos, Wiring Diagrams and Answers to Your Questions
Can Multiple Circuits Share A Junction Box? You can run multiple circuits through the same junction box. You cannot leave wiring splices outside an enclosure. This is an NEC rule. . But either just two circuits or even two voltages in dual gang box is allowed and is common. If you have two circuits (not an MWBC) on a duplex receptacle you need to break off .

That's what's known as a Multi-wire Branch Circuit, and it's perfectly acceptable if done properly. Though it sounds like yours is not. First, . Assuming that every conductor is spliced in the box (no unbroken pass-through), the Box Fill requirements of NFPA 70 Article 314.16 will call for a box of 18 cubic inches minimum. Find the cubic inch for each metal box in the . What about tie bars for multiple circuits on a common yoke device? How could that be accomplished if taken from different panels?
Yes, you can -- just mind the box fill and labeling, and make sure to keep your neutrals separated! A five gang box composed from gangable, 2¾" deep boxes as you .

Electrician told me I can run 12/3 for dishwasher and food disposer and have one receptacle under the sink with upper and bottom connected on different dedicated circuits but . Having multiple circuits there is ok but from panels in different units could present a problem. Yes this is the only box that feeds both apartments. the other dual facing boxes are . Answer: Yes, you can use two circuits in a dual gang box as long as the box is rated for multiple circuits and the circuits are properly wired and labeled. It is important to follow local electrical codes and consult a licensed electrician if you are unsure about the proper installation of multiple circuits in a single box.Can Multiple Circuits Share A Junction Box? You can run multiple circuits through the same junction box. You cannot leave wiring splices outside an enclosure. This is an NEC rule. Therefore, junction boxes are commonplace in most homes. It makes more sense to use one junction box where possible because it saves space and money.

But either just two circuits or even two voltages in dual gang box is allowed and is common. If you have two circuits (not an MWBC) on a duplex receptacle you need to break off the neutral tab too and run two independent neutrals to match the two hots.
That's what's known as a Multi-wire Branch Circuit, and it's perfectly acceptable if done properly. Though it sounds like yours is not. First, the ungrounded (hot) conductors must be on separate legs of the service. Secondly, the breaker(s) protecting the circuit must have the handles tied together, or a double pole breaker should be used.The answer is yes you can have 2 separate circuits in the same box (they can have a splice also but not needed in your case). The only concern would be the total box fill. Based on the NEC the wire fill would be calculated at 2.0 for each conductor for 14 . If I have a junction box where there are splices from several circuits, do I connect all ground wires from all circuits together in one bundle or do I do that for each circuit within the junction box? Assuming that every conductor is spliced in the box (no unbroken pass-through), the Box Fill requirements of NFPA 70 Article 314.16 will call for a box of 18 cubic inches minimum. Find the cubic inch for each metal box in the chart at NFPA 79 Article 314.16(A)
I need to bring five individual circuits into my bathroom/dressing room addition. I'd like to run THHN/THWN from the outdoor breaker panel, through conduit and into a junction box in the attic where everything will switch over to NM.
The voltage between conductors of two different grounded sources like this depends on which phase of each supply each conductor is on. You can actually change this difference by swapping phases on either or both circuits.
