Neutral vs ground wire? - Electrical Engineering Stack The neutral wire goes all the way back to the source, which is usually a pole top transformer or a generator. The wire can run many miles from that grounding rod -- and can have a potential difference. Having a separate ground and neutral has lots of safety benefits. Current should travel through that neutral and ground current should be zero. Understanding the Ground and Neutral of Electrical Wiring Ground wires and Neutral wires are separate wires that are vitally important for the home electrical system. A ground wire is not intended to be a current carrying conductor. To use a ground wire for anything other than a ground would be very dangerous and is not recommended.

Here is a typical connection wiring diagram for a light outlet, box and fixture connection. Please refer to these connection wiring diagrams to get the correct details on how the ground connections should be made before checking the wiring diagram you need to reference for your particular home wiring How to Identify Hot & Neutral Electrical Wiring | Hunker Identifying electrical wiring properly is an important step when replacing a light fixture, installing an outlet or handling other electrical work. The hot and neutral lines should be two distinct colors, but the colors can vary for the different wires. Learn how to identify wires for your safety. What do I do with the neutral and ground when wiring a Note that neither neutral nor ground are switched in the transfer switch. The generator can optionally be grounded to a rod. If you cannot lift the bond, disconnect the ground wire to the transfer switch at the generator (or don't run a ground wire at all).
