How to repair the phenomenon of water leakage and power jump in a hotel room

After the water leaked, the hotel room tripped, which indicated that the coil insulation was too low and caused the trip.

First, determine which line can't send electricity,

Then check the insulation of the lines with electrical instruments to determine which line is leaking or which two lines are short-circuited. The method is as follows,

Use a multimeter to check the following.

Measure the insulation resistance of live wire and zero wire, live wire to ground wire and zero wire to ground wire.

Knowing which line is missing, we are gradually narrowing the fault range by subsection search.
