ELECTRICAL SYSTEM

Generators / Charger

All electrical equipment fitted in your new
campervan can be run from either a
controlled generator or charger whose output
is maintained between 11volts and 14volts.

At least once every 3 years, the campervan
electrical installation should be inspected and
tested and a report on its condition obtained,
as prescribed in British Standard BS7671.

230v POWER SUPPLY

Mains Unit

The Mains Unit replaces the conventional
fuse box. Similar, but larger ones are often
fitted in new houses. The unit, normally
located on the front bed box, gives overloads
and earth leakage protection for the 230V
electrical supply in your campervan.

For normal operation all switches on the unit
need to be in the ON position. The switches
on the left of the unit are known as MCB’s
(miniature circuit breakers). These take the
place of the conventional fuse but are more
convenient. In the event of a fault the MCB
‘trips’ i.e. automatically moves to the OFF
position. After elimination of the fault the
MCB can be re-set by switching to the ON
position (against the spring pressure in an
upwards direction). If an earth fault develops,
or a person was to touch a live piece of
equipment, the leakage of current to earth
should immediately operate the RCD
(residual current device) and ‘trip’ the main
switch, to the OFF position. This switch can
only be re-set after elimination of the fault.

Please note:

In case of difficulty, consult an

approved electrical installation contractor
(who may be the local electricity board). It is
dangerous to attempt modifications and
additions yourself.

CAUTION:

Lamp holder-plugs (bayonet- cap

adaptors) should not be used under any
circumstances.

Resetting the RCD

To re-set, operate the switch as for MCB’s.
Periodically, the RCD should be checked by
operating the test button marked ‘T’. The unit
should immediately switch to the OFF
position. If the unit does not switch off then a
qualified electrician should be consulted. If
the unit does switch off, the test is complete
and the switch can be re-set restoring the
supply back to normal.

Please note:

Simultaneous operation of all

of the 230V mains electrical equipment may
not be possible. A typical UK site mains hook-
up point provides a maximum output of 16
amps and on some continental sites the
available output may be as low as 5 amps. If
your loading exceeds the site supply it may
trip the site circuit breaker. Please check the
available mains output with your site
operator. The following items need to be
added together if used simultaneously.

230V mains equipment typical consumption
figures:
• Refrigerator ............................... 0.50 amps
• Charger ....................................... 2.2 amps
• Water heater ............................... 3.9 amps
• Blown air heaters ........................ 8.5 amps
• Colour TV .................................. 3.33 amps

AUTOMATIC CHARGING SYSTEM

The battery charger will operate automatically
when the campervan is connected to the
mains outlet on a campervan site.

Note:

The charging unit only charges the

leisure battery not the vehicle battery.

When the campervan engine is running the
12V system will not operate with the
exception of the 12V refrigerator.
