Its product lineup includes specialized machinery such as the MM-4, a 3-axis CNC machining center; the TR-1 XP, a 2-axis horizontal flatbed CNC lathe; and the 4VS, a 3-axis vertical milling machine equipped with a moving table.
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 describe provides 70in³ of fill (14in³/gang as per the Steel City catalog).

Can two different circuits go through the same junction box? That is, two cables .
I have an existing junction box and currently 1 source from the basement going in, and one source coming out and that goes to a wall switch. If I want to connect a second wire to come from that junction box, would I just .
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 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 . The source of the emergency power does not have to be from a generator. Inverter systems with batteries also could qualify as part of an Article 700 system, therefore the wiring . 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 . Translation: "Yes, power wiring from different sources can be in the same conduit, box, or equipment cabinet." There is one thing you have to watch. The rules for low voltage - power limited circuits relax the rules for wiring .
Some DIY and "handyman" work can result in two branches hooked up to one receptacle. If they're on the same 120V leg, it'll appear to work just fine. 'sounds like the time . Just to rule out the simple solution, any chance the lighting is OK with a 120V power source, so you could run the fan and the light from the same 120V circuit? If I remember . Yes, you can -- just mind the box fill and labeling, and make sure to keep your neutrals separated!

I have an existing junction box and currently 1 source from the basement going in, and one source coming out and that goes to a wall switch. If I want to connect a second wire to come from that junction box, would I just attach all hot and all neutral wires together in the box? As a homeowner or DIYer, you might wonder if you can wire multiple circuits in one junction box. The answer is not a straightforward one, but this blog post will explain the different factors you should consider before making that decision. 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 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.
The source of the emergency power does not have to be from a generator. Inverter systems with batteries also could qualify as part of an Article 700 system, therefore the wiring would require two separate conduit systems.

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 connected except for the grounds if that is required. Yes, that is fine. The only restriction would be mixing voltage classes.
Translation: "Yes, power wiring from different sources can be in the same conduit, box, or equipment cabinet." There is one thing you have to watch. The rules for low voltage - power limited circuits relax the rules for wiring methods - you don't have to follow the Chapter 3 rules - BUT not in the same conduit or raceway. Some DIY and "handyman" work can result in two branches hooked up to one receptacle. If they're on the same 120V leg, it'll appear to work just fine. 'sounds like the time to call in a pro and let them sort it out.

Just to rule out the simple solution, any chance the lighting is OK with a 120V power source, so you could run the fan and the light from the same 120V circuit? If I remember right a lot of the LED drivers could take either. Yes, you can -- just mind the box fill and labeling, and make sure to keep your neutrals separated!
