Earthing system

Pompey boy

Recently mobile welfare cabins with integral generators were used on site.

Test sheets supplied gave the earthing system as IT. 

2 phase 3 wire

NO earth electrode was used when the suppliers tested before arrival on site.

On arrival on site an earth electrode was installed and the cabin was connected to this.

Is the cabin now a TT system?

    If it really is an IT system, connecting more earth electrodes to PE won't make it another type of earthing system - it will still be insulated from Earth.

    Was it really an IT system? It's unusual, especially if PE in the cabin is taken from the generator neutral.
