how to install a metal electrical outlet box
dual gang box multiple circuits
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 gauge wire and 2.25 for 12 gauge .Yes, you could combine two circuits in a 5 -gang box, but why? Not why "2 circuits", .Can two different circuits go through the same junction box? That is, two cables .
3 light switches in one box
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 . 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 .
I think your answer is Yes the HVAC people are correct, if you need to do some 24V and 120V switching in the same box and obviously the circuits are not connected. the 24V . You can buy a metal box and matching mud ring, the box has indents to hold the isolation blade that slot into the mud ring. Even plastic boxes have the same application!
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 . Multiwire circuits require connection to an n-pole breaker for n circuits. So two circuits require a double-pole breaker or two single-pole breakers with handles linked together. 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 .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 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. 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. 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.
I think your answer is Yes the HVAC people are correct, if you need to do some 24V and 120V switching in the same box and obviously the circuits are not connected. the 24V 18/2 is a class 2 circuit. You need 18/2 rated 600V or splice to a wire rated 600V like 14/2. You can buy a metal box and matching mud ring, the box has indents to hold the isolation blade that slot into the mud ring. Even plastic boxes have the same application! 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).

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.
