Important! The shower circuit should be separated from other circuits by at least

twice the diameter of the cable or conduit, and it should not be run through

thermally insulating material or in locations where the ambient temperature is

likely to exceed 30 °C. If any of these conditions are unavoidable, it is necessary

4. As a guide only, and in accordance with BS 7671 we recommend close circuit

protection:

i.e. 9.5 kW = 40 Amp, 10.8 kW = 45 Amp.

It is strongly recommended that a 30 mA Residual Current Device (RCD) is

included in the electrical circuit. This may be part of the consumer unit or a

separate unit. A separate, permanently connected supply is taken from the

consumer unit to the appliance through a double pole isolating switch, which

has at least 3 mm of contact separation. The switch can be a ceiling mounted

pullcord type within the shower room, or a wall mounted switch in an adjacent

room.
