ELECTRICAL SYSTEM
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 in the front bed box, gives overloads
and earth leakage protection for the 230V
electrical supply in your caravan.
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. 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 caravan 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 (Under counter) ..... 0.50 amps
• Refrigerator (Full height) ............. 1.0 amps
• Charger ....................................... 2.2 amps
• Water heaters ............................. 6.5 amps
• Blown air heaters ...................... 11.5 amps
• Colour TV .................................. 3.33 amps
• Microwave ................................. 4.00 amps
AUTOMATIC CHARGING SYSTEM
The battery charger will operate automatically
when the caravan is connected to the mains
outlet on a caravan site. The 12V system,
with the exception of the 12V refrigerator and
battery charging, will not operate when the
caravan is connected to the towing vehicle.
CHECK all caravan equipment is set-up to
accept the site supply before actually
switching on.
INTERNAL LIGHTS
Your new caravan is fitted with all LED
lighting.
MAXIMUM POWER RATINGS FOR
INTERNAL LIGHTS
(WHERE FITTED)
Type of Light Maximum Power Rating
Front window light ............................. 4 watts

depending on the location within the vehicle.
Please note: All LED units must be replaced
with like for like or manufacturers
recommended replacement.
Never replace an LED with one which has a
higher rating.
CAUTION: Do not look directly at LED lights.
