CONNECTION OF SERVICES
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 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
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 flexible 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 significance 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.
There are available several proprietary
makes of equipment for the purpose (e.g.
Martindale tester unit).
Check all motorhome 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
fitted in newer houses. The unit gives
overload and earth leakage protection for the
230v electrical supply in your motorhome.
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).
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 were 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 its OFF position.
This switch is only re-settable after
elimination of the fault.
