ELECTRICAL REQUIREMENTS
The installation, supply cable and circuit
protection must conform with 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.2)
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 consumer unit.
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.3)
.
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.
They will also check the main bonding.
