CIRCUIT PROTECTION

Schematic of installation circuit
ELECTRICAL REQUIREMENTS
The installation, supply cable and circuit
protection must conform with BS 7671 (IEE
wiring regulations) and be sufficient for the
amperage required.
The following notes are for guidance only:
1
The shower must only be connected to a
230-240V ac supply. If you are installing a
shower with a kilowatt rating above 9kW, it
is advisable to contact the local electricity
supply company.
1.1
The electrical rating of the shower is shown
on the rating label
(Fig.3)
within the unit.
2
Before making any sort of electrical
connection within the installation make
sure that no terminal is live. If in any doubt,
switch off the whole installation at the mains
supply and remove the correct fuse.
3
The shower must be connected to its own
independent electrical circuit.
IT MUST NOT
be connected to a ring main, spur, socket
outlet, lighting circuit or cooker circuit.
3.1
The electrical supply must be adequate for
the loading of the unit and existing circuits.
4
Check your consumer unit (main fuse box)
has a main switch rating of 80A or above
and that it has a spare fuse way which will
take the fuse or Miniature Circuit Breaker
(MCB) necessary for the shower
(Fig.4)
.
4.1
If your consumer unit has a rating below
80A or if there is no spare fuse way, then the
installation will not be straightforward and
may require a new consumer unit serving
the house or just the shower.
4.2
You will need to contact the local electricity
company. They will check the supply and
carry out what is necessary.
5
For close circuit protection
DO NOT
use a
rewireable fuse. Instead use a suitably rated
Miniature Circuit Breaker (MCB) or cartridge
fuse
(see Table A)
.
5.1
A 30mA residual current device (RCD)
MUST
be installed in all UK electric and
pumped shower circuits. This may be part of
the consumer unit or a separate unit.
