Volatge Issues

Signs you may have a voltage problem

Occasionally an issue may arise in maintaining a consistent level of voltage. Common signs of a voltage problem are:

  • Lights that dim when other appliances are in use.
  • Kettle is slow to boil.
  • Electrical motors that fail to start first time.

Note: These problems can also occur if you have exceeded the capacity of your electricity connection. In this case, you will need to increase the level of your supply.
