The neutral is the normal "return" wire: in systems where
the load is supplied from only one hot (or "live") wire, the
neutral completes the circuit and carries current back from
the load to the power station.

The ground or "earth" wire is a circuit's safety protective
wire that normally carries no current

Answer / avd

Neutral - Neutral is the star point of a 3 phase
transformer with star connection of secondary. This star
point will have zero potential under balanced load
condition. This star point may or may not be connected to

Earthing - Earthing is ground potential (ZERO) connected to
mother earth via earthing pit.

Ceiling fan motor wiring Hi, I have 2 ceiling fans broken. The receiver/control units burned out due to lightening. One Harbor Breeze and one Hunter's I took them apart (remove receiver units). Now on both of the motor I see 4 wires coming out from each motor I really want to know the function of each wire. Are there anyway I can test to see which is which? After searching forums I know these 4 wires are from 2 sets of coils inside the motor, one is Start winding and the other is Runing winding I could not find the receiver/control unit any where, so I am planing to buy Capacitors and universal remote controls to make the fans run again. Anyone has any idea how to do the wiring, please help Thnks
