Why use a hot wire and a cold wire created outside, using electricity the electric meter does not rotate, if you know the principle of construction of a single-phase meter, you will easily know that the meter is connected correctly and incorrectly, when the meter is connected. If the electric meter is wrong, I use the hot wire and the self-made cool wire outside the meter will not rotate because at this time the current and voltage are not flowing through the electric meter.
