Boiler for static caravan - no earth

[loz2754]

The On Site Guide has a good section on earthing of generator sets. A floating earth is not to be used to supply more than one item of class 1 equipment, so a neutral to earth link will be needed I think.

3800kw generator

Is that 3800kW, 3.8kW, 3800W or 3.8kVa?

Sounds like the generator has no N-E link.

What's the make and model?

As mentioned above the generator probably doesn't have L-N linked , Iv owned a few small (under 15 KVA) generators and all of them have not had a L-N link. The earthing point on the chassis of the generator just connects to the cpc/earth pins of the outlets,

The earth in this case is basically a bonding conductor and making sure if there is a fault then the earth for each appliances is at the same potential, and the set up is normally isolated from true earth (see attached picture)

It is normally very easy to see if the generator is this configuration by just removing the cover on the part with the socket outlets, obviously with the generator off
