You have an open neutral. When the wire length from the breaker panel to the service outlet is long and the connected equipment is pulling a large amount of current, the resistance in the wire will cause a voltage drop along the NEUTRAL wire. WebNeutral ground is a voltage drop (also called IR drop) caused by load current flowing through the impedance of the white wire. If you want to check neutral and ground loads then check to see which is greater. Hosted By: WolfPack Advising. But sometimes there exists some measure of potential difference between them. "Neutral to ground voltages at branch receptacles are directly proportional to circuit length and circuit current and inversely proportional to conductor size or cross-sectional area. Home Improvement Stack Exchange is a question and answer site for contractors and serious DIYers. The cost for an electrician to wire a whole house typically costs $8,000.
