What to do in the Event of a Power Cut

by denergi admin


Though power cuts are not a common occurrence they are not unheard of either and so it is important to be aware of what to do in the event of one.

The first step should always be to check the trip switch which can be found in your fuse box (if you don’t know where this is it is vitally important to locate it and make yourself familiar with it now incase of an emergency). The trip switch only trips when there is a problem with the wiring of the internal circuit and not the incoming supply. You can test this by following these steps:

  • Make sure the Trip switch is in the ‘On’ position
  • Press the ‘push to test’ button
  • If this doesn’t trip the switch then there is no incoming supply of electricity
  • If the switch does trip then it is either because of a faulty appliance, a light may have gone or there is an issue with the internal wiring.


Once you have confirmed that it is not an internal fault you need to check to see if other buildings in the area have been affected as this will be one of the questions you are asked when you contact your Distribution Network Operator.

Finally, once you have established whether it is an issue with your supply or a localised problem you must contact your Distribution Network Operator. The country is broken up into LDZs (Local Distribution Zones) and each one is maintained by a different Distribution Network Operator. To find out which company you need to contact and the relevant telephone number please follow this link.

Important things to help you prepare for, and get through, a power cut:

  • Always make sure you have candles or torches in an obvious and easy to reach place, make sure any lit candles are placed in a safe place and are not left unattended
  • Leave at least one light switch turned on so that you know when the power has returned
  • If possible keep everyone in one room and wrap up warm if it’s winter
  • As far as possible unplug electrical appliances
  • Once power has returned make sure that any food in freezers has not thawed


It is always wise to be prepared for these circumstances and to be aware of the location of your fuse box and how it works. These simple steps will help you to deal with a power cut efficiently and hopefully minimise the length of time you are without power.
