Electrical Requirements
Shower unit
45A Double pole isolating
switch (e.g. Pull cord)
30mA RCD
(May be part of consumer unit)
Consumer unit (80A
minimum isolating
switch rating)
For adequate circuit protection DO NOT use a rewire-able fuse. Instead use a suitably rated
miniature circuit breaker or cartridge fuse.
A 30mA residual current device (RCD) must be installed.
A 45 amp double pole isolating switch with a minimum contact gap of 3mm in both poles must be
incorporated in the circuit.
The isolating switch must have a mechanical indicator showing when the switch is in the OFF
position, and the wiring must be directly connected to the switch.
The isolating switch must be accessible and clearly identifiable, although out of reach of a person
using a fixed bath or shower. The cord of a cord-operated switch should be placed so that it is not
possible to touch the switch body whilst standing in a bath or shower cubicle.
Where shower cubicles are located outside of a bathroom, all socket outlets in the room must be
protected by a 30mA RCD. Consult the wiring regulations.
It is recommended to use the shortest cable route possible from the consumer unit to the shower.
All components must be rated and installed in accordance with wiring regulations. This appliance must be earthed.
