NEVER START YOUR MOTORHOME
ENGINE WHILST HOOKED UP TO
A 230V SUPPLY. This can lead to
damage to the PDU and cause internal
fires.
The electrical system in your motorhome is
comprised of a 230v and 12v circuit. When
connected to a mains hook your vehicle will
take its power from the 230v mains feed. All
sockets and connections (including 12v) will
receive power and function in the correct
manner. The leisure battery will also be
charged.
If no mains connection is available the
electrical system will run via the 12v circuit.
All sockets and connections will function in
the correct manner, however, usage time will
be governed by the amount of charge in your
leisure battery (this can be checked via the
Seattle control panel).
When the motorhome engine is
running power to the habitation area
is isolated. Therefore sockets and
connections will not function.

The Power Distribution Unit (PDU) is
responsible for distributing power to the
electrical outlets and systems throughout
your motorhome. It also houses Miniature
Circuit Breakers (MCD) (1) the Residual
Current Device (RCD) (2) and all in-line fuses

(3). 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.
In the event of an overload the MCBs "trips"
and automatically moves to the OFF position.
After the overload has been removed the MCB
can be reset by switching to the ON position.
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 and "trip" the main switch to its OFF
position. This switch is only resettable after
elimination of the fault.
To reset, operate the switch as for MCBs.
Everytime you connect to a site supply the
RCD should be tested to ensure correct
functionality.
It is possible that all of the 230v mains
electrical equipment may not operate
simultaneously. Having too many appliances
switched on at the same time will trip the MCB.
This is a safety measure.
Many motorhome site mains hook-up points
provide a maximum output of 16 amps. 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.
When replacing fuses you should always
ensure that you replace the old fuse with a
fuse that is the same type and has the same
rating.
Always check the available mains
output in amps with your site
operator.
No appliance should be used outside
while connected to an internal socket.
