No Earth


Recommended Posts

I am thinking of going to a site in Norway which in the description in the Caravan club guide say it has 16a electric but no earth. I have an adaptor which reverses polaarity but what can i do or what do i need to do about "no earth". Advice please!!

You could create your own by taking a cable from your van chassis to a long tent peg in the ground underneath. This is what I always do with the genny, earth it to the ground.

I do not mean to be dismissive of your question but why worry about it? If it's safe for other caravanners and campers then it will be safe for you. I think it is an accepted fact that UK electrical safety standards are OTT and of the belt and braces variety. The rest of the world seems to safely use a system different to ours without mishap

We used to exhibit industrial machinery in Germany. When the German electrician wasn't looking, we would join the neutral and the earth in order to get single phase (for the kettle) from 3 phase.

 

I wouldn't worry too much as UK stds are the highest in Europe.

There are many who use generators without an earth however its not something I would fancy doing.

Modern suitcase type generators are designed to be used as a standalone supply and don't require an earth. Unless the generator is modified then all an additional earth acheives is offers reassurance to the owner that they have done something to make it safer,whilst in reality it does nothing

I am not an electrical expert and try to follow the advice in these matters from the Caravan Club i. e don't use non earthed supply BUT there have been sites I want to use and have just had to ignore it. As others have said everyone else on the site is at the same risk. Incidentally there are items that wont work without an earth, I have a portable air conditioning unit that does not.

You should never use a supply without an earth in the UK or for most of mainland EU.

If there is no earth return then in the event of a short circuit there is an increased risk of fire and you would be relying on the RCD to see the fault which it isn't designed to do.

The difference with parts of Norway is that they use the IT system ( floating neutral ) whereas most modern systems in mainland EU use a TNC-S system which requires an earth.

I never bother about reverse polarity but I would be concerned about no earth on a TNC-S network.

To have an earth you would require a metre long pole driven into the ground connected to the chassis .

Not a recommended solution,better off not connecting!

But without a Earth the RCB will not work ? A chassis is bonded to the Earth system in a caravan . Does not a household earth rely on a earth in the ground usually the incoming cable surround ?

RCD's don't require an earth to operate they operate on the imbalance between incoming and outgoig current.

Most modern supply systems use the TNCS system where the neutral is earthed at multiple points along it's route and acts as the continous protective earth conductor,older networks, mainly urban where there are a lot uf UG cables,use the metallic cable sheath for the earth return.

You are correct that a functional earth is required for the safe operation of the supply but driving a 1metre spike in the ground without knowing what is below ie HV/LV cables. gas and water mains etc may be even more hazardous or costly than no earth.
If a site doesn't have an earth then it begs the question what else is faulty?

The only safe alternative is not connect to the system.

In the case of the OP an IT system doesn't require a continous protective earth and is relatively safe but not as safe as TNC-S

Just to add to the confusion, pme, protective multiple earth, if you look at some of the telly wag poles you can see the earth cable running up from the ground to join up to the neutral line. :-)

Hi

 

I've been on a total of twelve Scandinavian sites over the past seven weeks including four in Norway, I have checked every one for both polarity and earth, all twelve have been fine.
