![]() ![]() It’s possible to safely have two circuits feeding one receptacle, if you have a hot/neutral pair for each segment. If you’re not sure if your outlets are grounded, a receptacle analyzer will tell you. And if conduit or sheathing is used as a ground path, connections must be tight. Ground wires must be firmly connected at all points. Do all grounds in a box need to be connected? A double pole switch can be used to control light and a fan or 2 lights on separate circuits. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit. ![]() Two separate circuits are controlled by one switch. It’s easier to pull one three wire for two circuits, than 2 separate two wires. Recent code requires them to be on a double pole breaker though. Can two different circuits share a neutral?Īs long as the phase conductors are on different “phases” it’s fine. Other than that you can have as many circuits as you have devices in the box, as long as you have adequate room in the box for splices and connections. The only real limitation in a box is wire-fill and low-voltage separation. You must keep connections coming from different circuits separate from each other. It can be done without any hassle if you know about the basics of it. Yes, there is nothing wrong or unsafe in wiring more than one circuit in a single junction box.
