2. There is a place with leakage.
3 is the line load overload.
If you don't have a leak warranty, it's a problem of 1 and 3 Anyway, let's change it to an empty open, and it is estimated that the problem of empty opening is bigger.
There may be a problem with the wiring or the appliance may have other leakage or overload.
The power of the four bulbs of the bath bomb is generally not less than 800W, and the power of the small kitchen treasure is generally about 2500W, so that the total power will reach 8300W (or more), so that the current of the line will reach 38A, if only an air switch is set for the line, then the air switch will use 40A, and the total air switch should not be less than 63A.
The most important thing is to determine the power of the electrical appliances used and the capacity of the matching line, such as the square copper wire matching 16A, the 4 square matching 25A, and the 6 square matching 32A, which should be matched according to the power line.
220V electrical appliances can produce ampere current per kilowatt, and 20 ampere switches should not exceed 4 kilowatts.
If your power number is correct, the water heater should be about 15A current, 4 square lines are enough, and the 63A air switch is too large. It is estimated that you still have high-current electrical appliances in your bathroom, such as bath bombs, oil cubes, etc. If the line is fine, the quality of the air opening may not be very good. >>>More
