please read up on how alternating current works, alternating current doesn't come in one wire and go out the other. that's how direct current works. alternating current goes back and forth on the same wire. 3 wires come from the transformer on the power pole to the meter. 2 insulated carry 120 volts each the non insulated wire is a ground. three wires come from the meter to the breaker panel, again 2 carry 120 volts and one is a ground. the 2 wires that carry 120 volts connect to the main breaker the main breaker supplies power to the circuit breakers thru L1 and L2 ( bar where the circuit breakers mount) the wire that goes from the breaker panel to the outlet consists of 3 wires one black one white and one bare wire. the black wire is used as the hot wire and connects to the circuit breaker. the white wire and bare wires both connect to the ground /neutral block in the breaker panel, ground/ neutral block is connected to a ground rod that is driven into the earth creating an earth ground. the whit or neutral wire. the neural wire creates an area of low electrical pressure allowing neutrons to flow. there should be no electrical current on the neural wire in a 120 volt circuit. if there were it would energize the ground wires and the earth around the ground rod. in 240 volt circuits the white and black wires carry 120 volts each from L1 and L2 making 240 volts in a 3 wire 240 volt circuit the ground wire creates low pressure allowing neutrons to flow. does this sound right Walta or is it still very dangerous. if so please explain why the earth and ground wires aren't energized by the neutral wire that you claim carries 120 volts back to the breaker panel
