    I've relocated a 3 phase wattmeter. The meter wheel is turning even with the circuit breaker feeding its loads is off. With all the other cb's in the board off it still continues to turn. Could it be that the wattmeter is faulty or maybe something not right with the neutral connection? :confused:

    Take readings of the AC voltage of the neutral to ground and to the three phase lines with the CB's off.
