electrical code two circuits in one junction 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 . There are many parts of a house even longtime homeowners don’t know the names of. This guide will introduce you to the names of lesser-known house parts, helping you communicate more effectively about your home.

Gang boxes come in varying versions, from 2-gang, 3-gang, and 4-gang. They all feature the same structure and are made of metal. These types of junction boxes are used for internal electrical wiring and are easy to make and manage.
single junction box wiring multiple circuits
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 right). Since the load for Circuit 2 doesn't have a matching neutral, it's . 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 they are on one circuit as you described, on one switch like this one: 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 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 .
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 be on an AFCI breaker (to comply with smoke detector rules).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 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 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 . I was not aware that you could mix circuits from one panel that is 480 / 277 with another one that is 120 /208. Here is a photo of the switch and how it is wired. Quote: "Ideal for . 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. 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 right). Since the load for Circuit 2 doesn't have a matching neutral, it's connected to Circuit 1's neutral line.
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 they are on one circuit as you described, on one switch like this one: 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.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 .
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 be on an AFCI breaker (to comply with smoke detector rules).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?
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.
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.
I was not aware that you could mix circuits from one panel that is 480 / 277 with another one that is 120 /208. Here is a photo of the switch and how it is wired. Quote: "Ideal for bi-level switched restrooms with light and fan.

When determining what color metal roof is best for your home, consider your local climate. In hot, sunny areas, lighter colors are typically preferred due to their reflective properties. This helps reduce the heat island effect and keeps your home cooler.
