Electric Shower Supply Cables
SITE REQUIREMENTS - ELECTRICAL
The supply cable selected for installation must conform to the relevant table in the current I.E.E. regulations.
The size of cable required is determined by the kW rating of the shower, the distance between
the shower and the consumer unit and the way the cable is fitted.
The minimum size will be 6mm2 but in some cases 10mm2 is strongly recommended.
To enhance electrical safety a 30mA RCD (Residual Current Device) should be installed in all UK electric and pumped shower circuits.
This may be part of the consumer unit or a separate unit.
IMPORTANT! If upgrading to a higher Kilowatt shower
it is essential to ensure the electrical supply and shower cable is adequate for the increased load
