THE ELECTRICAL SYSTEM
• 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 resettable after
elimination of the fault.
• To re-set, operate the switch as for MCBs
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 qualified 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 qualified 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.
It is possible that all of the 230v mains
electrical equipment may not 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 park’s 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:
Fridge 0.5 amps
Colour TV 2.5 amps
Charger 1.0 amps
Microwave 10.0 amps
Air conditioning 4.0 amps
Blown/convection air heating 8.7 amps
Kettle (2000w) 8.7 amps
