Electric water heater sometimes power leakage switch trip, sometimes over a period of time trip, what is the reason?
one. May be a safe leak protection device bad two. The heating tube is broken
If the electric tube is not a problem, you do not put the boilers on the ground, the metal containers may have leakage of the earth. Then pay attention to the water when you do not touch to avoid electric shock.
If you can continue to close the switch after the trip, it means no ground. It may be your leakage switch rated current is a bit small, a light, instantaneous current is relatively large, resulting in tripping. Change the switch on it!
