CIRCUIT PROTECTION

W-006-A

WARNING!

THIS APPLIANCE MUST BE EARTHED

E-002-A

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.

6

 

A 45 amp double pole isolating switch with 
a minimum contact gap of 3 mm in both 
poles must be incorporated in the circuit.

6.1

  It must have a mechanical indicator showing 

when the switch is in the OFF position, and 
the wiring must be connected to the switch 
without the use of a plug or socket outlet.

6.2

  The switch must be accessible and clearly 

identifiable, but out of reach of a person 
using a fixed bath or shower, except for the 
cord of a cord operated switch, and should 
be placed so that it is not possible to touch 
the switch body while standing in a bath or 
shower cubicle. It should be readily 
accessible to switch off after using the 
shower.

7

 

Where shower cubicles are located in any 
rooms other than bathrooms, all socket 
outlets in those rooms must be protected by 
a 30mA RCD.

8

 

The current carrying capacity of the cable 
must be at least that of the shower circuit 
protection 

(see Table B).

8.1

  To obtain full advantage of the power 

provided by the shower, use the shortest 
cable route possible from the consumer unit 
to the shower.

8.2

  It is also necessary to satisfy the 

disconnection time and thermal constraints 
which means that for any given combination 
of current demand, voltage drop and cable 
size, there is a maximum permissible circuit 
length.

9

 

The shower circuit should be separated from 
other circuits by at least twice the diameter 
of the cable or conduit.

9.1

  The current rating will be reduced if the 

cabling is bunched with others, surrounded 
by thermal loft or wall insulation or placed in 
areas where the ambient temperature is 
above 30°C. Under these conditions, 
derating factors apply and it is necessary to 
select a larger cable size.

9.2

 

In the majority of installations, the cable 
will unavoidably be placed in one or more 
of the above conditions. This being so, it 
is strongly recommended to use a 
minimum of 10mm cabling throughout 
the shower installation.

9.3

  In any event, it is essential that individual 

site conditions are assessed by a competent 
electrician in order to determine the correct 
cable size and permissible circuit length.
