What is the cause of excessive current flow through the leakage protector?

Reasons for excessive leakage protector current

1.Overload

The rated current of the leakage protector is determined, if the circuit load exceeds the rated current, it will cause the leakage protector current is too large, false action or inaction and other problems.

2. Short circuit

Short circuit is one of the main causes of leakage protector current is too large. When the circuit is short-circuited, the current rises sharply, exceeding the rated current of the leakage protector, resulting in the leakage protector can not work properly.

3. Leakage

Leakage is also one of the causes of leakage protector current is too large. When the electrical insulation failure, the current will flow from the ground back to the AC power line, forming a leakage, when the leakage protector will trigger excessive current.
