Replace the fuses

The fuses in the fuse box ensure there's not too much electricity through a group of devices, as a safety precaution. If there's too much electricity through the fuse a wire inside wilt melt, which disconnects the power: the fuse is 'blown'. In case of power failure, it's the tenants responsibility to replace the fuses if necessary. You will recognise a blown fuse when the middle piece of metal is gone.

A fuse is made for single use only, you can't repair it. If the fuse is blown, please replace it by a new one before putting the power back on.

What to do when a fuse has blown?

  • Turn off the faulty device and unplug the power cord
  • Replace the blown fuse
  • If necessary, turn on the group switch or circuit breaker

If you don't know which device is causing the problem:

  • Turn off the group of the blown switch
  • Disconnect all electric devices in the group by unplugging them
  • Replace the fuse.
  • Reconnent all devices one by one until the fuse is blown again. That way you'll find out which device is causing problem.

Prevent system overload

The use of many power demanding devices in one electricity group may cause a fuse to fail. One electricity group is generally adjusted to a capacity of 16 Amps (3000 Watts), but a washer or dryer often already needs 2000-2500 Watts. When you connect a coffee machine (650 Watts) to the same group and use it at the same time, the fuse or the machine will fail. This is a safeguard to prevent fire!


To avoid unnecessary costs, it’s best to disconnect certain electrical appliances (e.g. old electrical ovens, old toasters). More information on main fuses and power failures.
