[QUOTE="curious-one, post: 403422, member: 26856"] I'm trying to see if I can do a basic test of resistance under load which I believe is part of the standard tests an electrician would do before energising a circuit. I can do a simple dead test by connecting L and N with a terminal block and testing round trip from the last point, again same for L and E and then N and E, but if I remember my school days right (and it's possible I don't!) the resistance figure will change once a load is applied, so the dead test is little more than a continuity test with a DMM, but the resistance under load is what sets things on fire. I'm basically trying to see if I can cover some basic tests so when someone comes out, I can hopefully make life much easier (and less costly, I'll admit, car broke the other day so I'm poorer than I was!) in the hope they can run their fluke or megger across everything and all will be well. Thanks. [/QUOTE]
