Re: CQD answer published Wednesday, March 22, 2017 - Equipotential Bonding
This is pertaining to the question on attaching the equipotential bond to the service panel. In a situation where you lose the service neutral and your pool equipment and everything associated with it is attached, how will it be determined that the neutral doesn't exist?

Answer:
Hey Eric thanks for your follow up question. If a service neutral connection becomes disconnected usually it will be very evident by malfunctioning equipment. Line to neutral connected loads become connected in series across the line to line voltage. The path back to the utility transformer using only the earth has much higher impedance that the neutral conductor. Other paths can also exist, such as metal piping systems that are interconnected between more than one service supplied building or structure.
