Reference Method 102

[GaryMc]

Hi there, I'm needing some guidance in how to interpret this reference method.

How could one be sure that the installed cable behind the plasterboard ( in my case) is actually touching the inner wall ie the plasterboard?

I'm going to have a 25mm service void on my insulated stud wall, but I'm thinking once the plasterboard is fitted it may touch the cable now and then but not consistently, so do I use method 103 but i would need to wire my ring in 6mm cable and that's not going to happen lol.

Can anybody please help and give there thoughts on this?

Thanks.
Gary.

Install it in conduit which is reference method A and gives the minimum requirement of 20 amps (for 2.5mm) per leg of the ring

Thanks for the reply Ian, I was thinking that I'll go with that method. I've made a couple of smaller rings and took heavy fixed appliances off the ring and gave them dedicated circuits so the loads on each ring will be minimised.
Cheers Ian.

It's a big question, I can't believe anyone can really guarantee 102, yet we specify it as if it is likely!

I would suggest that in 99.99% of cases although 102 is specified, installed, tested, and successfully running out there, it's mostly 103 in actuality
