WebIn electrical engineering, ground and neutral are circuit conductors used in alternating current (AC) electrical systems. The ground circuit is connected to earth, and neutral circuit is usually connected to ground. As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. WebJan 28, 2024 · While it is a grounded conductor, the grounded phase of a corner-grounded delta grid is not technically a neutral. In those cases, all three wires would need to be the full size, and the neutral sizing algorithm wouldn't apply. If it were a 3-phase/4-wire system, I agree with Post #2. augie47 Moderator.
