Can you have 2 different circuits in the same box?
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).
How do you wire two switches in the same box?
Youtube quote:Cut a hole on your drywall. And insert it that way or if you have exposed studs you can use this new work which is same thing it comes with two nails. So when you're looking at your jbox.
Can you use two switches one circuit?
Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit. A double pole switch can be used to control light and a fan or 2 lights on separate circuits.
Can 2 circuits share an outlet?
The only time this is safe is the receptacle is a dual receptacle with the tabs removed. Then it is actually 2 separate receptacles with separate power sources. Even then, it is not a good idea unless it is a Multiwire Branch Circuit (MWBC).
How many circuits are allowed in a junction box?
There are no limits on the number of junction boxes (without devices) in any particular circuit. Each piece of ‘utilization equipment’ reduces the maximum allowable load by it nameplate rating, 180va for each receptacle, and each light fixture at its maximum labeled lamp wattage.
Do all grounds in a box need to be connected?
Ground wires must be firmly connected at all points. And if conduit or sheathing is used as a ground path, connections must be tight. If you’re not sure if your outlets are grounded, a receptacle analyzer will tell you.
Can 2 circuits share a neutral?
as long as the phase conductors are on different “phases” it’s fine. Recent code requires them to be on a double pole breaker though. I do it as much as possible in houses. It’s easier to pull one three wire for two circuits, than 2 separate two wires.
Can 3 circuits share a neutral?
If it is a 3 phase circuit you can have 3 hots per neutral as long as you are using the A, B & C phases for each neutral. A neutral is a current carrying conductor and must be the same size as the hot.
Can wires touch in junction box?
Mistake: No electrical box | Never connect wires outside of electrical boxes. Junction boxes (or a J box) protect the connections from accidental damage and contain sparks and heat from a loose connection or short circuit.
Can a junction box be behind drywall?
Junction box covers must remain accessible; they cannot be covered with drywall or other surface material.
What happens if a ground wire touches metal?
If the ground wires touch the metal box the breaker pops and the ground wires spark. The main feed comes out of a ceiling light fixture box. The ceiling box is two wire BX. I’m using NM to feed the junction box.
