THEELECTRICALSYSTEM
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(e.g.Martindale
testerunit).
Ifitcanbeachieved,itispreferabletoconnect
livetolive,andneutraltoneutraltomaintain
fullelectricalprotection.
Checkallcaravan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ttedin
newerhouses.
The unit gives overload and earth leakage
protection for the 230v electrical supply in
yourcaravan.
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 MCBs
(miniaturecircuitbreakers).
Thesetaketheplaceoftheconventionalfuse
butaremoreconvenient.
In the event of a fault the MCB trips e.g.
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MCBs
Every time you connect to a site supply 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 qualied
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.
Havingtoomanyappliancesswitched
onatthesametimewilltriptheMCB.
Thisisasafetymeasure.

Alwaysdisconnecttheelectrical
connectorbetweenthetowingvehicle
andthecaravanbeforeconnectinga
230vsupplytothecaravanandbefore
chargingthecaravanbatterybyany
othermeans.
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sitesupply
it may trip the park’s circuit breaker. Please
check the available mains output with your
siteoperator.
