Power Cable Neutral and System Grounding PEguru
WebOct 14, 2024 · Here's an image of 240VAC versus 240VDC. Stipulate that the live wire has 240VAC relative to the neutral (return) wire and that the neutral wire is held at 0V. This … In 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. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. C… dirty hairbrush
