Got me there,no idea

It's the reg that requires you to have done a full investigation of the relevant parts of the existing installation with regards to safety and suitability for alteration before you started work.

Wouldn’t that be down to the electrical consultant etc,he’s ordered the works,we’ve installed what they asked for,completed & tested.

Depends really what was in the work order, but at the end of the day the cert needs signing and that signature verifies compliance with BS7671.

So if he'd asked for a 8kw shower to be connected to the lighting circuit and the existing 6a mcb replaced with a 40a you'd do it, test it, and cert it?
Just saying.

A rcd used for fault protection live to earth would tackle the high zs on the circuit problem provided its high because of the length and not because of poor/ loose connections anywhere on the ring.
A live - neutral loop test should be undertaken to confirm that for short circuit protection the protective device will operate within the required time.

Yes agree,can’t understand how this as come about,no cerfication,the actual works for power is not a lot,it’s just alterations or repositioning .
There is no spec to the works,ain’t got a clue why not.
Also getting no answers f anyone.

It’s not an ideal world and there’s jobs were no spec exists you are the designer ,installer the lot. I’ve done many a job were the so called spec is basically ‘I want a socket there and there’ from the customer.

I wasn't aware that there is a required disconnection time for short circuit.
