[QUOTE="sparkysam, post: 250511, member: 15914"] Hi there all, got my 2391 theory in a couple of weeks and ran through some questions with the tutor, but 2 tutors giving different answers, what is the definitive answer , A test of IR is to be carried out on a 230v circuit that contains a surge protective device which cannot be disconnected , state the ... A) test voltage to be applied B)conductors between which the test is to be conducted between I answered 250v dc and tested between live conductors to earth , , it's not definitive in the GN3 either The tutor says test at 250v between all conductors as it doesn't state in the GN3 if you reduce the voltage to also test between live conductors to earth , then the other tutor said the same as me, WTF!!
