Technical Detail and Advice for Electrical Hook Up

The equipment we use to provide Electric Hook-ups (EHUs) is all located above ground.
Please be careful when moving around the EHU-equipped areas, whether by vehicle or on
foot, since there will be cables and connection boxes between pitches.
Power is supplied by on-site generators. While every practical measure is taken to ensure that
the noise from these is minimal, it is not possible to soundproof them entirely.
What appliances can you use?
Temporary sites supply a maximum 6 amps, which means at any one time the total of all
appliances in use at an individual pitch, must not exceed 6 amps. All caravanners are urged to
limit the use of electricity during periods of high demand by using low wattage appliances.
The list to the right is shown as a guide to the amount electricity appliances use.
From these ratings you can gauge that at 230 volts an appliance of 1 kW (1000 watts) uses
about 4.3 amps, so you can work out the others. Fuses used in plugs should be the size
recommended by the appliance manufacturer. Before replacing any blown fuse ascertain the
cause. Never increase the size of the fuse above the rating specified.
Use of generated electricity will not affect your caravan’s/motorhome normal 12 volt
electrical system directly; it may keep an on-board battery charged up (through a suitable
charger) to help keep the 12 volt electrical system working. All electrical equipment used in
your caravan/motorhome should preferably be double insulated and show the BEAB or CE
Approval sign.

How to Connect and Disconnect
ALWAYS in this order

1. Check your caravan/motohome isolating switch is at ‘OFF’.
2. Uncoil the connecting cable from the drum (a coiled cable with current flowing through it
may overheat).
3. Take your cable and insert the connector (female end) into the caravan inlet.
4. Insert the plug (male end) into the site outlet socket and turn it clockwise until it locks.
5. Switch your caravan isolating switch to ‘ON’.
6 Preferably insert a polarity tester into one of the 3-pin sockets in the caravan to check all
connections are correctly wired. Never leave it in the socket. The supply must not be used if
the polarity is incorrect.


1. Switch your caravan isolating switch to ‘OFF’.
2. At the site supply socket, press the release button and withdraw the plug.
3. Disconnect the cable from the caravan.
1. If at any time you do not receive power or have any other electrical problem which you do
not understand a qualified electrician may be needed, particularly if there is a fault that keeps
2. If you overload your mains system a circuit breaker will disconnect your supply. Go to the
external socket outlet and reset the trip switch for your particular plug socket.
3. Please be aware if you connect faulty appliances to the system the safety devices may
disconnect not only your power, but also to other outfits.
4. Should a fault occur do not investigate anything unless you have disconnected from the
supply. The trip in your van may need to be reset; know where to find it.
5. If your cable is damaged, never cut, rejoin or tape- up and never wrap any connection in
polythene sheets as the condensation that forms will easily conduct live electricity
