Possible causes include “too high power consumption” and “temporary current leakage.”

Please consult an electrical construction shop regarding an increase in power capacity or repair of current leakage location.

There is a possibility of current leakage. Please consult an electrical construction shop.

Check which circuit has a current leakage!
If the main breaker is on but the switch stops in the middle position when a circuit breaker is raised (turned on), that circuit has a current leakage. The breaker for the circuit where the leakage is occurring cannot be used. Leave it in the down (off) position and consult an electrical construction shop. Other breakers can be used.
