A relative of mine has just discovered that the house they've been living in for 7 years doesn't have an Earth! It seems that whoever rewired the place last connected the main earth cable into the cutout of a TNS system but there was no actual link from the incoming armour of the cable to the earth block.
Their sparky discovered this when he came to test after installing a couple of sockets. They called out the DNO who confirmed his suspicions. The DNO then advised that either an earth rod be fitted or that they should apply for PME.
Apparently if they opt for PME it will take about six weeks to be installed.
My question is, what should they do in the meantime? They have an RCD which they know does trip but how effective will this be if there isn't a 'proper earth'? Will the sparky fit an earth rod untill PME is available.
Just curious really - but would appreciate your thoughts.
