Ir tests

[huntos33]

Just testing a 3 bed house i've re wired, its a empty property totaly gutted and re furbed Re plastered etc... Just doing my IR Tests on my rings and getting results around 129 meg at 500v nothing connected anywhere and no neons etc, Should i expect to be getting >500 as with all other curcuits ive tested?. Just seems odd to me these are lower than the rest

damp plaster? anyway 129Meg. is a well good reading. don't worry.

Wondered about damp, thanks telectrix

I always Con checked and IR tested the cable when it was new and still on the drum before i used it just to be on the safe side. Never found owt wrong, but never say never.
But i wouldnt worry, although you would expect the meter to go off the scale, 129 is still good, and as Tel says, probably damp.

Re test in a couple of days and compare results

Check all connections are tight and have a good amount of conductor in the terminal, this can sometimes lower your reading.

To the OP, you state a rewire..may I ask the test method you are using and where abouts you are placing your testing probes/croc clips in relation to the circuits in question ?

i would hope he's clipping to the bare ends of the stripped conductors.

Well Tel great minds lol..I was just wondering if he was buzzing it from the incomer on the bus bar or even the N/L out on the RCBO both can throw a wobbler on an IR

yep. IR testing is for the circuit/s alone. should never IR test with RCDs or any other sensitive equipment connected.
