two breakers 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 . Use the right equipment: TIG welding requires a power source, a TIG torch, a filler rod, and a gas cylinder. The equipment should be of good quality and in good working condition to ensure consistent welds.

Typically you use an approved "handle tie" - a piece of plastic or metal that fits between two breakers. A 2-pole breaker is an expensive way to do that same thing. This rule does not apply to you if your work is prior to your . Sound like someone miswired a junction box and fed the circuit from two power sources. Or, it was a multiwre circuit that was wired wrong when a receptacle was replaced. .

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 safest way to do this is to use a full sized two pole breaker. You can also install a 240v receptacle in that box at this point too. They do make a duplex with a 120v and a 240v .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 . That would be like installing a sub panel where one circuit from the main panel feeds into another box with two breakers that serve your two new sub circuits. Or, are you just .

Can two different circuits go through the same junction box? That is, two cables enter from different breakers and they tie to cables exiting, but the two circuits aren't .The two hots in the 12/3 connect to two different breakers, right next to each other. My design is to use this line to power two circuits, each with 3 outlets, wired in 12/2. To connect the 12/3 to the two 12/2s, I have them all running into a junction box. My plan is to connect each hot from the 12/3 to the hots on the new 12/2s, and pigtail . I think most code tries to do away with two separate breakers to the same junction/outlet box, unless both breakers can be tied together. . @crip659 nothing wrong with two different breakers in one box. Happens all the time in kitchens and bathrooms. Just can't combine on same yoke. – manassehkatz-Moving 2 Codidact.

But it would be protected by the fused disconnect. Basically 60A breaker at panel to a junction box near the unit outside, junction box feeds 20A fused disconnect and 50A fused disconnect. 6GA THHN wires for the run from breaker box to junction box, and junction box to disconnects. Meaning I had to turn off both breakers to kill the outlet (and they are not adjascent breakers that are joined with a pin so if one trips, both trips). I am curious about my options with 2 breakers running into one box and your guys thoughts on which option may be best. Add second outlet, each outlet would be connected to a single breaker.If one opening in a junction box has 4 or more wires (excluding ground) coming out of it and they are of multiple colors, that’s likely a conduit install.

two circuits in one box

Yep, there's a reason they should be on a two pole breaker, or tied between two adjacent breakers: They have to be separate phases (180 degrees apart) otherwise the neutral might get overloaded. Different phases cause a "push-pull" effect on the neutral that keeps its current as the difference between the hots; same phase would cause the .There are three switch boxes containing more than one switch on the affected circuit(s). One 2-gang controls a ceiling light on one circuit and another light on another circuit which I have confirmed is not related to this situation. The other two switch boxes are each 3-gang and AFAIK everything they are connected to is affected by this situation.

Each color represents a circuit controlled by a different switch at the breaker. The problem is at the red colored junction box. I was changing the old 3 pronged outlet with a new one and the old outlet had 3 black wires and a single white wire connected. They were all backstabbed in the 4 available slots so one black wire was in a neutral slot.

Would I be better off combining the two in a junction box above the panel and bringing only one cable into the panel, or should I bring both into the panel and double tap a breaker (the breakers are Homeline and are rated for double taps). I'm leaning toward the junction box, but I'm interested in hearing opinions.

Well, you can run two totally separate circuits to the box, from two toally separate single-pole breakers. That way if one trips, the other does not. Nothing wrong with that. You can also run a "Multi Wire Branch Circuit" (MWBC) from a two-pole breaker (a fault on either will shut both down) with a single neutral and two hots.

Perhaps if the two subpanels are adjacent and used only for space, they can be imagined as one but if one of the subpanels serves the garage, or the pool, or the extension then running a circuit from there to a part of the house served buy another subpanel and sharing a junction box there IMO should be avoided even if it's allowed. –I've seen situations where two circuts are run to the same junction box, and then split off from there. In modern wiring both hot wires would share the neutral wire. A mis-wiring in the junction box could join both breakers together, causing the need to flip both breakers to disable the power to the lights and applicances.My research suggests that I can replace the two existing 15 amp breakers with a new two pole 15 amp breaker. However I'm unsure as to how this should be wired into the box. The two pole breakers that I have been able to find all have just one connection for a neutral as they are produced assuming the use of 3 wire in a new application.

If breaker # 1 is powered by leg A of the power coming into the panel and breaker # 7 is powered by leg A of the power coming in the panel and the 2 circuits have power meeting each other in an enclosure such as a junction box you could potentially have 2 separate breakers control two separate circuits at the same time. MWBC. There are normal situations, especially with dishwashers, where there is more than one circuit in the same cable. So it is very likely that you do have two circuit breakers controlling the same junction box or cable. Is this . Sound like someone miswired a junction box and fed the circuit from two power sources. Or, it was a multiwre circuit that was wired wrong when a receptacle was replaced. You may have to check each receptacle and light switch to make sure there is only one line wire coming in. . You should immediately unhook the circuit wire from one of the .

( The box is grounded via one of the branch circuits.) . (switch or outlet) but it could also be in a ceiling fixture, or hidden in a hard to access space in a junction box Good luck Reply reply Newdad746 • Thank you for the response. However, it seems that it is only one circuit on two breakers. It is all in the same MC. Reply reply Home . In newer houses The two circuits must be on a double pole breaker for the smallest gauge wire used in the two circuits (e.g., 14 Ga. ==> 15 amps)In older houses code did not require the double pole or handle tie breakers. The two breakers should be ganged together, so that if one trips, both will trip, and all junction boxes in the circuits .I do not personally find that added junction boxes are preferable in any way to making splices in the breaker panel. . no grounds, junctions without boxes, hidden boxes, overfilled boxes, two breakers on one circuit, and more). So far, I've been putting all the lighting on one 15A circuit, but have debated with myself and my husband whether .

If I don't replace the fixture box, won't I need to use a cover plate - Not exactly ideal in the middle of the ceiling lol. Also after a bit more back tracing I found the /3 actually originates from a /2 at the breaker, and the splits in the /3 at the first junction box - like the did it so they only had to pull one wire instead of two /2 wires.Junction Box has a hot red and black 12/3 wire, 2 breakers turn BOTH wires on and off regardless of the position of the other breaker . I am replacing the outlets/switches in a relatives home, and am stumped by this one. A junction box has a 12/3 wire coming in along with 2 other 12/2 wires (out to a switch, and to another outlet), however with .Two breakers for one outlet? . Either cross wired in a junction box that is carrying both circuits, or it's a multi-wire branch circuit (shared neutral). Are they adjacent breakers? If you open up the panel, does one of them have a red wire and the other have a black wire?

Replace the existing disconnect with a R3 weatherproof junction box. Connect the j-box to the 2 disconnects. Pull the new circuit (#12's) through the junction box (leave a loop in the junction box for future) to the disconnect for the heat pump. The existing A/C wires (#10's) can be spliced in the junction box to extend them to the disconnect. That would be like installing a sub panel where one circuit from the main panel feeds into another box with two breakers that serve your two new sub circuits. . I know I can branch from a switch but it's on the other side of the basement so I'd rather make a junction box in the middle with one supply going left and the other going right. Upvote

Naturally, a lot of boxes got broken and inspector's response was "well, just order a new one and I'll see y'all on Monday." So yeah, some inspectors are cool, others are confident morons who waste businesses' time and money with their errors.Basically, I turned on EVERYTHING in the house. I made sure there was something plugged into each outlet and then I went through breaker by breaker, turning each off, one at a time and seeing what each breaker controlled. Out of 40 breakers, I have successfully identified 38. What do I do with the other two that I can't figure out.

I tore into the fixture and there are three 12-2 NM cables coming into its junction box. Disconnecting them all and testing: #1 is energized by one breaker, #2 is energized by the other breaker, and #3 is a switch leg/loop (zero ohms when the switch is .
