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.
