can you have more than one circuit inna junction box Customer: Can you have two breakered circuits going to the same junction box? I have a box that has a double outlet on one circuit and a light switch on a separate circuit (both 15 amps), all in . Use this junction box sizing calculator to determine the recommended dimensions of a junction box depending on the number of straight and angle pulls entering it and meet the National Electrical Code®.

This electrical box is usually called a 1900 box because that was the original part number from Bossert almost a hundred years ago. Called a 4" box because of its 4" width, it is the most common box used when a simple switchbox isn't big enough.
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 . Since the load for Circuit 2 doesn't have a matching neutral, it's connected to Circuit 1's neutral line. And before you ask, Circuit 1 and 2 are not MWBC circuits. Each one can be turned on/off independently.You can add as many junction boxes as you want to a circuit. But if you want a single box to accommodate multiple circuits, the size is your only limitation. You can use as many circuits as .Junction Box Wiring and Multiple Circuits. As stated in this question, if the junction box has the required cubic inches for the wiring that will be installed then yes, it is acceptable to have more .
Customer: Can you have two breakered circuits going to the same junction box? I have a box that has a double outlet on one circuit and a light switch on a separate circuit (both 15 amps), all in . My question is - can two NM cables be pulled into one knockout in a metal 1900 box? This is a standard 4" box with the preinstalled clamps, two openings on top and two on . 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 . My local code states that you can have up to three current carrying conductors in a conduit without making proximity adjustments to the ampacity. I'd rather run two conduits than .
Neutral wires from more than one circuit MUST be kept separate. Think about it -- if you joined the neutrals from more than one circuit, you could get more than the rated . 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. 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. Since the load for Circuit 2 doesn't have a matching neutral, it's connected to Circuit 1's neutral line. And before you ask, Circuit 1 and 2 are not MWBC circuits. Each one can be turned on/off independently.
two circuits in one box
You can add as many junction boxes as you want to a circuit. But if you want a single box to accommodate multiple circuits, the size is your only limitation. You can use as many circuits as you want if the box is large enough to hold them.
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 .Junction Box Wiring and Multiple Circuits. As stated in this question, if the junction box has the required cubic inches for the wiring that will be installed then yes, it is acceptable to have more than one circuit in the same electrical box or junction box.
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?Customer: Can you have two breakered circuits going to the same junction box? I have a box that has a double outlet on one circuit and a light switch on a separate circuit (both 15 amps), all in the same box - is this legal? My question is - can two NM cables be pulled into one knockout in a metal 1900 box? This is a standard 4" box with the preinstalled clamps, two openings on top and two on the bottom. The scenario is three NM cables only coming into the top of the box. 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.
