Hi All
Just a quick question on insulation resistance testing i know how to do it but what i dont get is i know its just an exam question and if you got readings like bs7671 further investigation would take place ie
250v------------->0.5Mohm
500v------------->1Mohm
etc
just been watching Niceic dvd and he gets >299Mohm @ 500v & >99.9Mohm @ 250v ! ive got a kewtech kt61 and mine wont give symbol > and how come in bs7671 the min is that low ?
The guy in the niceic dvd also on 250v test got 0.71Mohms on selv and said its of course a fail ! how come if its above 0.5Mohm ?
