I discussed a problem last week on here about a customer in the next street to mine with the same house, built in 1934 which was rewired 15 years ago with the old Wylex wire fuses, mine has TNS fitted but with 16th edition , I am to fit a new boiler and done the walk round but noticed the 16mm was never connected to the outer Armour of the cable of the incomer and that it has never been had an earh strap fitted since new in 1934.
This has been relying on the services for earthing, I rang EDF they said that they would charge to TNS, or TNCS it.
on this forum I was advised just to TT it and now that makes sense to me.
Old couple with a shot boiler and not a lot of money.
As a lot of you guys have a lot more experience of conversion to TT than me, your advice would be appreciated.
Do I Bang a rod in, test the Ze test it all and make sure that it meets the correct Zs readings on all circuits for disconnection times and Rcd my boiler, then again fixed Equipment does not have to be RCD'd.
Should it be a new Board with twin 30ma RCD or what as TT is quite grey area to me
Don't want to go to over the top but it's got to be right.
Look forward to your views on this.
