Electricity Safety, Troubleshooting and Other Information What to Do When the Lights Go Out

What should I do if only one lamp or appliance fails to light?

First check the bulb to see if it is loose or is burned out. Be careful not to touch the bulb with your bare hands. Use a cloth in case the bulb is hot. Then simply tighten it or replace it with a new bulb. A chipped or loose socket may be the cause of a light or appliance failure. You may need to replace or retighten the socket in this case. If the cause is neither the bulb nor the socket, check the electrical cord for cracked insulation, fraying or other damage. Please replace any damaged cords with new ones.

What should I do if none of the electric appliances in one room light up?

This is probably caused by a defective appliance or a damaged cord. Otherwise, the excessive use of electricity in the room might have caused the circuit breaker to trip or the fuse in the safety device to blow (burn out). Remove the appliances in use from the outlet and pull up (down) the knob of the branch circuit breaker or replace the blown out fuse with a new one. An electrician can provide you with a new fuse. If a seal on each circuit breaker tells you which room it leads to, you can easily know which room has a problem.

What should I do if none of the appliances in the whole house light?

When you use too many electric appliances at the same time, the SB fails. When this occurs, first stop using some of the appliances and pull the knob of the SB down (up). When the leak circuit breaker fails because of a short-circuit or a jolt of lightning, do as follows:

7.A leak circuit breaker may fail immediately after you switch on a branch circuit breaker. If so, switch off that branch circuit breaker, and switch on the leak circuit breaker again.

Now you can use electricity except for the areas of your home to which the off-branch circuit breaker supplies electricity. We also recommend that you ask an electrician to check the off-circuit.

When the power goes out in your neighborhood, please call your nearby Chubu Electric Power customer service office. When the demand for electricity increases in your neighborhood or at a resident's request, we will either add an electrical line or move poles. On such occasions, a short interruption might sometimes be necessary due to construction. We will notify you about the construction in advance via postcard, etc. If there is an electrical power blackout because of lightning, a typhoon, or other accident, please wait for power recovery.

Please let us know if you have any questions concerning your service.
