For Residents Frequently Asked Questions (FAQs)

Electric Breaker

The circuit breaker hasn’t tripped, but the lighting in the room went out

Please refer to the relevant section depending on your situation:
If power is automatically restored after a few seconds
If power is not automatically restored within a few seconds
If only lighting or specific appliances are not working

If power is automatically restored after a few seconds:


The electricity consumption may have exceeded the contracted amperage, and the electric meter (digital meter) may have shout off the supply. It is not a malfunction.
※If the circuit breaker trips due to excessive electricity usage, power will automatically be restored within a few seconds to about one minute in buildings equipped with digital meters. 

If frequent power outages occur, the contracted power (amperage) may be insufficient for electricity you are using.Please reduce the number of appliances used simultaneously or consult your electricity provider about changing your contracted amperage.

※If you are a resident of a building with digital electric meter, you do not have to notify our company when you change the amperage.

<How to distinguish digital and analog meters.>

An electricity meter with a liquid crystal display (LCD) that displays electrical energy is a digital meter. On the other hand, a meter with a rotating dial is an analog meter.



If power is not automatically restored within a few seconds:

It might be a regional power outage. Please contact the electricity company for power outage information.


If only lighting or specific appliances are not working:
The cause might be a blown bulb or malfunction of the unit. If the cause is lighting, please replace the bulb. For other appliances, please refer to the user’s manual or the manufacturer's instructions.
