Electric Shower Installation - Power Requirements
Before deciding what make or kilowatt rating of electric shower you wish to use, the first place to start is at the main fuse board or consumer unit. You need to assess if you have a spare way on your consumer unit with sufficient rating for an electric shower, it will require connection to a separate fused electrical supply circuit.

In accordance with BS7671 a 30mA Residual Current Device (RCD) must be fitted. This may be part of the consumer unit or a separate unit and must have a tripping current of no more than 30 mA.

All electric showers require a dedicated cable from the consumer unit to the shower itself, you will need to consider the correct sizing of any new or existing cabling to ensure it is adequate for the Electric shower you have chosen.

The size of the cable and fuse will depend on the electrical power in kW of the shower, but 10mm2 cable is recommended, as this would mean you can replace the shower in the future, without having to install a larger cable
