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.
The following items need to be added together
if used simultaneously.
