live to live, and neutral to neutral to maintain full
electrical protection.
Check all caravan equipment is set-up to accept the
site supply before actually switching on.
Mains unit
The mains unit replaces the conventional fuse box.
Similar, but larger units are often tted in newer
houses.
The unit gives overload 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 M.C.B.’s (miniature circuit
breakers).
These take the place of the conventional fuse but
are more convenient.
In the event of a fault the M.C.B. ‘trips’ i.e.
automatically moves to the OFF position.
After elimination of the fault the M.C.B. 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 is only re-settable after elimination of
the fault.
To re-set, operate the switch as for M.C.B’s.
Every time you connect to a site supply 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 qualied electrician should be consulted.
If the unit does switch off, the test is complete and
the switch can be reset restoring the supply back
to normal.
Having too many appliances switched on
at the same time will trip the MCB. This is
a safety measure.
It is essential that connections are made
exactly as shown. If terminal markings are
not in accordance with the diagram they
must be ignored. If in doubt consult a
qualied electrician.
Always disconnect the electrical connector
between the towing vehicle and the
caravan before connecting a 230v supply
to the caravan and before charging the
caravan battery by any other means.
It is possible that all of the 230v mains electrical
equipment may not be able to be operated
simultaneously. A typical UK caravan park 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 parks 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 gures:
Fridge .............................................. 0.5 amps
Colour TV ..........................................2.5 amps
Charger .............................................1.0 amps
Microwave .........................................10 amps
Air conditioning................................... 4 amps
Blown/convection air heating ................8.7 amps
17. THE ELECTRICAL SYSTEM 12 VOLT.
Your caravan is tted with a 12 volt charger as
standard. This converts the 230 volt AC supply into
12 volt DC. This enables the 12 volt equipment in
the caravan to function and charges the caravan
leisure battery. A fully charged caravan leisure
battery should read 13.8 volts on the voltmeter
mounted in the control panel.
The charger is capable of charging leisure batteries
and will not overcharge.
The 12 volt system is designed to operate with a
leisure battery in circuit and should not be turned
on without one connected. The 12 volt supply to the
caravan services can be isolated via the 12 volt on/
off switch on the control panel.
Auxiliary Battery storage/mains inlet
The battery and 230V mains inlet are located in a
special locker mounted in the side of the caravan.
The door frame has a cable recess allowing the door
to be locked when the mains cable is connected.
This locker will accommodate a battery up to 110
amperes/hours capacity.
The battery must be placed in the
tray provided in the battery storage
compartment, and must be used at all
