I am only a trainee ( so don't bite too much) a friend of mine called out british gas to fix his boiler.. Whilst he was there he checked the electrics.. Said the earth loop was greater than 200 ohms on the ring main and they should get a spark out asap.. So he asked could i pop down and and have a look before they call in a spark ( to see if i could see what the issue was ) it is a TT supply as far as i can tell with a wylex board rewireable fuses with separate RCD installed.. Tested the board.. 0.28ohms..PFC was 0.956kA.. Tested the rcd at 1/2.. X1 and x5.. All within limits.. Tested the socket where the PLUMBER checked and here is where i get lost.. Earth fault loop impedance Test with a megger1730.. 1st test setting was L-L 0.60.. L-N was 0.60 and the setting l-pe was 800ohms.. Is the setting L-PE the important reading yes? And whats the outcome..
