3.4.2 Electrics 230v
For your safety it is IMPORTANT that you follow these connection instructions each time your trailer
is connected to a 230v mains supply. This section assumes that the system is complete and that an
auxiliary leisure battery has been installed.
Overview
The 230v mains electrical system obtains its power from an external power supply point via a flexible
supply cable plugged into the power input socket located on the LHS of the trailer. Power from this
socket is fed into the Power Distribution Unit (P.D.U.) located under the LH bench seat in the living
area. From the P.D.U. power is supplied to 3pin sockets and the battery charger. If a fridge is fitted a
socket for it is located under the RH bench.
3.4.2.1 Power Distribution Unit (P.D.U.)
The P.D.U. provides overload and earth leakage protection for the 230v electrical supply in your
trailer via a M.C.B and a R.C.D.
For normal operation all switches on the box need to be in the ON position. The switch to the right
on the R.C.D (residual current device) is the mains switch to turn 230v power inside the trailer on or
off.
The switches on the left of the box are known as M.C.B (miniature circuit breakers) and take the
place of conventional fuses. In the event of a fault the M.C.B “trips” by automatically moving into
the OFF position. After the elimination of the fault the M.C.B can be re-set by switching to the ON
position.
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 R.C.D (residual current device) and “trip” the main switch,
to the OFF position. This switch is only re-settable after the elimination of the fault, reset by
switching to the ON position.
Every time you connect to a to an external power supply point the R.C.D should be checked by
operating the test button marked “T”. The R.C.D 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 reset restoring the supply back
to normal.
•
Having too many appliances switched on at the same time will trip the M.C.B. This is a safety
measure.
•
It is possible that all of the 230v mains electrical equipment may not be able to be operated
simultaneously. A typical UK caravan park mains hook up point provides a maximum output
of 16 amps and on some continental sites the available output may be as low as 5 amps. If
your loading exceeds the sites supply it may “trip” the sites circuit breaker. Check with your
site operator the available “amps” output.
