: Please explain me the electrical wiring system in detail.the function of neutral,hot and earth.
: bye and thanks
Highly simplified view:
- Neutral and hot carry the electricla current which powers your electrical devices
- earth/ground wire is an additional wire for safety, it is used to ground metal parts of devices and electrical wiring so thay can't become "live" (dangrous to touch)
- earth/ground is connected to the ground (groundign rods or other grounding electrodes in the soil)
- earth and neutral wires are usually connected together in some part of the electrical wiring (which means that neutral wire is roughly at ground potential)
