metal boxes earthing

[John-SJW]

I have seen a few metal back boxes that have no earth terminal lug. Do the regs state the metal back box must have an earth wire to it? The earth on the socket/FCU is earthed to the backbox via the socket faceplate securing screws.

There's a new build estate around here where all the switches are 2 plated and the neutral's and earth's are in connector blocks in a metal back box.

They ‘should’ be parked in the earth terminal on the box

Totally agree or at the least the back box should be picked up.
What code would you give that on an EICR?

If the metal Box is not earthed then a C2

If the metal Box is not earthed then a C2

but not if the faceplate is metal and is itself earthed.

Thx. I agree with not creating unnecessary threads. When you type in a title to a new thread, the system does a search presenting threads of similar topic, so as not to craete an unnecessary thread. That is why my titles tend to tell the story. None came up.
