Filling in test certificate

Gazthesparky · Sep 15, 2017

Just a quick couple of questions its a Friday and now sitting doing paperwork with a couple of beers.

Im filling in a certificate to cover a consumer unit change and having a mental block.

There is a 3phase supply coming into the building and then the flat I was working in has a 6oamp supply.

noting the supply characteristics is it the 3phase supply that you note down and then later list the 60amp sub main or is it the 60amp sub main I list as the supply characteristics

This is the supply would you agree that it is a TNS supply ? tested line to earth and it was o.17 ohms and Line to Neutral 0.19

The earth to the flat is bolted off of the metal trunking that comes from the supply head

cheers

agree, and that head that's almost as old as me and pete added together wants binning.

i mean the head for the bin, not me and pete.

thanks for that just needed some clarification and defiantly agree the head needs binning but thats not my problem I'm just doing work in one of the flats its the factor company who's responsible for the communal area/supplys.

A lot of the tenements in Glasgow are supplied like this
