Specifications

The only certain way of making
equipment safe is to unplug it.
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.
If it can be achieved, it is preferable to
connect live to live, and neutral to neutral
to maintain full electrical protection.
CHECK all motorhome equipment is set-
up to accept the site supply before
actually switching on.
MAINS UNIT
The Mains Unit replaces the conventional
fusebox. Similar, but larger ones are often
fitted in new 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).
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.
Periodically 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 re-set
restoring the supply back to normal.
Note:
It is possible that all of the 230V mains
electrical equipment may not be able to
be operated simultaneously. A typical
UK motorhome site mains hook up
point provides a maximum output of 10
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 site circuit
breaker. Please check the available
mains output with your site operator.
