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.The Neutral and Ground are generally connected together at your service panel, not at your devices. At the device, neutral is the path for return..Best answer · 4The ground wire is physically connected to a rod that penetrates the soil usually near the breaker box-- this is your local potential. The neutral..4The ground is redundant for safety. It's not uncommon to accidentally to switch hot and neutral during installation of outlets or other things. The..3Both neutral and ground are closely related to each other, but a neutral represents a reference point within a power distribution and a return path..1 Understanding the Ground and Neutral of Electrical Wiring How to Configure the Ground and Neutral of Electrical Wiring: 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.
