Lighting circuits not protected by RCD

[Des 56]

If it's cables are run through walls without adequate mechanical protection i.e. to switches surely it's code 2 if there's no RCD and the conditions of reg 522.6.6/OSG 7.3.2 aren't met

The esc recomendation for the above is code 4
The original question I would say code 4 as well

Maybe the lighting is surface clipped or trunked and we are all wrong

Exactly.

Which is why we need to know the exact reasons that create the requirement of a code 4.
A simple 'not RCD protected' isn't very defined.

The trouble with Code 4 is that things are considered dangerous now could all be assigned the Code 4.
- RCDs weren't originally in the Regs
- CPC on lighting circuits weren't originally in the Regs
and so the list goes on ... Where do you draw the line ... ?

Only things that are non compliant to BS7671 are assigned to code 4, irrelevant of if they are safe or not.

The new 3 code condition report system is designed to stop electricians giving clients a list of problems without the work getting rectified.
