Site cabin EICR

I also am wondering what this electrode is actually achieving, seeing as the fault path on any of the circuits will not actually leave the cabin itself?? 

If this is really true, then in many ways  it is more like a vehicle on the move, (like a carnival float) and I'd agree no real need to have an electrode.

But, should there be any connection to the outside (are there lights or cameras on the outside of the box over the door perhaps) or any credible fault where if damaged then exposed parts may be at more than one voltage, then it really does matter.

The other obvious one is if ever someone plugs in an extension lead and walks out the door with it, to power anything outside, then  it becomes very important.

I am aware of a nasty near miss where an extension lead supplying a flood light got snagged on a fence wire hidden in a hedge (cable was thrown / dragged over the hedge) and by really bad luck, connected just the brown core rather  resistively  to earth. Every thing carried  on working just fine, but the trailer and vehicle all became very tingly at that point.
