C2 or C3 on recent EICR

[newfutile]

During an inspection i have come across a class 2 light fitting with a cpc that’s is not connected to MET.

initially i put this as a C2 but I’m wondering what others thing?
where is the danger as it is?

It's not so much the fact that the current light fitting doesn't need a CPC, but more that fact that current CPC is not connected to earth - which is much more of a concern!

C2 for a CPC not connected to MET

We it would certainly result in this C2 from BPG#4:
Earth fault loop impedance value greater than that required for operation of the protective device within the time prescribed in the version of BS 7671/IEE/IET Wiring Regulations or manufacturers’ published data current at the time of installation

There are some notes/guidance for light circuits installed using cable without a CPC as they would have been acceptable pre-1966, but after that there is no real excuse for not having a usable CPC.

Indeed. Quite possibly C3 for a class 2 fitting with no CPC, but having a CPC present but not connected to earth at the other end, C2 for me.

Exactly, the CPC should be usable if anyone chooses to fit class 1 lights or switches.
