ELECTRIC SYSTEM
THE ELECTRICAL SYSTEM – 230 VOLT
As in the home, care must be exercised when
handling mains electricity. Your attention is
drawn to the following notice as laid down
by the Institute of Electrical Engineers.
Instructions for electricity supply - low voltage
(230 v)
On arrival at Motorhome site
Before connecting the Motorhome installation
to the main supply:
• Check that the mains supply is suitable
for your installation and appliances, i.e.
whether it is a.c. or d.c. and whether it is at
the correct voltage, frequency and polarity.
• Check that your installations will be
properly earthed. Never accept a supply
from a socket outlet or plug having only two
pins, or from a lighting outlet.
• Check that any residual current device
(earth leakage circuit breaker) in the mains
supply to the Motorhome has been tested
within the last month. After connection to
site supply, test again.
• Make sure that the switch at the site supply
point is off.
• Make sure that the Motorhome RCD unit is
switched off.
• Remove any cover from the electricity inlet
provided on the Motorhome, and insert the
connector of the supply exible cable.
• Remove any cover from the socket outlet
provided at the site and connect the plug
at the other end of the supply exible cable
to this. Switch on the main switch at the
site supply point. (If there is not switch the
power will already be live)
• Leave spare cable in loose coils on the oor
and not on a drum.
• Switch on the Motorhome RCD unit.
• It is at this point it is good to check the trip
switch. Reposition it to see if this activates
the ow.
• In case of doubt, consult the site owner or
his agent.
On leaving Motorhome site
• Switch off the site supply.
• Switch off the Motorhome RCD unit.
• Then disconnect the pitch lead.
• Switch off and disconnect portable
appliances.
• Stow cable in a tidy state.
• In case of difculty consult an approved
electrical installation contractor (who
may be the local electricity board). It is
dangerous to attempt modications and
additions yourself.
• Lamp holder-plugs (bayonet-cap adapters)
should not in any circumstances be used.
• Replace the cover of the socket outlet at
the site supply point. It is dangerous to
leave the supply socket or supply exible
cable live.
• Every 12 months, the Motorhome electrical
installation should be inspected and tested
and a report on its condition obtained as
prescribed in the Regulations for Electrical
Installations, published by the Institute of
Electrical Engineers.
Generators
• Switch off all appliances, the miniature
circuit breakers and the residual current
device.
• Start the generator and allow to run for a
few minutes to stabilise.
• Connect the motorhome to the generator
using an approved hook up cable.
• Switch on 16 amp miniature circuit breaker.
• Switch on the residual current device.
• Switch on the fridge (230 volt phase) or plug
in a 230V light to one of the 13amp sockets.
This is to provide a load on the generator
and help remove any “spikes” in the supply
which can damage the charger unit.
• Switch on the 5amp miniature circuit
breaker and any other appliances you
require.
It is always advisable to have at least one other
mains appliance switched on with the charger
unit to minimise the chance of damage to it.
Do not connect the 12 volt output of the
generator to the battery terminals. The AC
ripple must not exceed 10%.
Overseas connections
Connection to a mains voltage supply overseas
requires particular attention.
Care must be taken when connecting supplies
abroad since the supplies can have reverse
polarity.
The signicance of reverse polarity is that
when equipment is switched off it may not be
electrically isolated.
The only certain way of making equipment safe
is to unplug it.
Motorhome Service Systems
A means of checking the polarity of the mains
supply when overseas is useful.
