This is a description of how a NEUTRAL works off the secondary side of a transformer. This circuit is 15 Volts! It is NOT meant to accurately represent any particular electrical system used for commercial or residential service in any part of the world. It is simply showing how loads are balanced and unbalanced by the absence or presence of the neutral wire. The system discussed here employs NO GROUND and has nothing to do with grounding, bonding or earthing of electrical systems. It is not intended to teach electrical safety or wiring methods.
