When the automatic water heater is turned off, the trip voltage is normal, the line is normal and the load trips. Ask experts for advice.

1, first of all, we should doubt the external problems of the cabinet. Shake the car to the test position and then close the test position. If it is normal, push the car to the working position. If not, consider whether there is a problem with the load. Your phenomenon should not be a load problem.

2. I have encountered this phenomenon, and I laugh at myself when I think about it. After closing, the trip circuit automatically activates (the schematic diagram needs to be read carefully) and trips. After inspection, it is found that the stop button does not rebound (reset) after being pressed.

3. Trust the prompt of "Central Signal Screen Display" and check whether the trip circuit is open.
