Ho Ho Ho, ahem, I mean Hi Hi Hi.....
I was at a empty property on Friday and was (for the first time ever) stumped by what the supply types earth was. It consisted of three cloth covered singles ran from underground to the DB in steel(?) conduit. The three cores were L, N &E. The earth was connected to the MET but upon testing found the earth was non existent; reading was >2.99k ohms, even when the bonding was reconnected, though the water was part plastic pipes... I am going to test my TT install at home in the morning to make sure my MFT is not jiggered, before I contact the REC.
It is fairly obviously not TNCS. Given the way the supply enters the property is there likely to be a connection to a sheath underground? If the supply is TNS then I take it that the REC have a duty to maintain the earth. Will the REC know what the supply type is meant to be?
Sorry if this is slightly incoherent, bit late at night to be writing!!
Sorry no pics taken.
Regards, Neil
