Job in a old shop, new board put in about 10 years ago, every test is fine but when we come to do the Live/Earth insulation test we get a low reading of 0.6M, now it's the same when turn off all the circuits! have dissconnected the neutral and nothing, tested from the live side of the switch to earth and THATS fine but when we try and do every circuit individually it's 0.6M (on or off) really stuck with this one!
any ideas would be great
