Hi every one, I have sited my caravan and as I was on a job today I just happened to look at a earth spike and thought would that be a good idea to put a earth spike next to caravan and run a earth cable in.
Caravans are earthed though the hook up.
When I was in the army we used to earth our electronics repair wagons and our generators but this was to make the circuit.
If caravans needed to be earthed separately the manufacturers would include an earth point.

When there's a fault on some other part of the site's electrical installation (or a neighbouring property), and the fault current decides to flow back through your earth spike and EHU lead, it won't seem like such a good idea
A caravan plugged into ehu is wired to earth, ie no different to an electrical appliance plugged into a socket in a house. Any earth spike would be elsewhere in the electricity supply.
A caravan is predominantly wood. Even the aluminium skin is held together on sealant so earthing part of a caravan doesn't earth it all. That's why the lights have earth wires and don't rely on getting an earth through the body as is done with cars.
Earthing can be dangerous anyway. That's why shaver sockets which have no earth are the only sockets allowed in a bathroom. If there is no route for the current to take to earth or neutral (incidentally with PME systems the neutral is the earth), electricity is harmless.

It's normally the lack of earthing which can be dangerous.
The reason why only certain types of shaver sockets are allowed in bathrooms is due to them having isolating transformers. The shaver circuit is then electrically separate from the 'main' supply.

The neutral is always into the property,the earth is connected to the neutral on the supply side of the supply cutout,they then become a combined neutral and earth.
Socket outlets are permitted in bathrooms provided they are 3m outside zone 1 and are protected by a 30mA RCD.
