pir code

[welsh spark]

Evening all,
i just wanted to know your opinions on a instalation im looking at its domestic and has 1 30ma main switch covering the whole board im thinking of the discrimination and what code to put down on my pir oviously code 4 dose not comply with bs7671.but do you think i need to put any other codes for this thanks in advance Alan

I would give it a code 4 and nothing more.

 

[Spudnik]

I think a 4 is fine.

Might sound like an odd question Alan, but are you with a particular Registration body - NIC, Elecsa or NAPIT?

I know even if you are you`re probably not paying to notify PIRs, but they may publish specific guidance on how to code these.

Otherwise i`d go with your 4 mate.

Regards, another Alan

Definitely code 4 if there is no valid reason for using an RCD as incommer. What is the earthing arrangement and what is the Ze reading.
