Hi, this one is stumping me.
I have been asked to look at a swiming pool installation. The supply to house is tns, with a submain running out to a pool plant building, the installer has atempted to put the pool side on a seperate TT, however the gas pipe running to the pool building is in copper from house so introduces the TNS into TT. Ok i can live with that its not on a PME.
My main problem is the submain. The installer extended an existing 2 core armoured, however they decided in not to conect the armour up in the underground joint. so in effect we have a submain that only a CPC (armour) for half its length that is earthed.
Digging up the submain or the joint is not an option, my only solution is running an additional CPC ie green n yellow, from one end of the submain to the other. this would follow a different root to the submain.
Anyones thoughts would be great
