[QUOTE="Traineeboy, post: 505801, member: 32807"] I’m just wanting to Clarify something. am I correct is thinking to do a blanket Insulation resistance test at 250v would help identify any possible issues before a board change is done. i.e if you link the neutral bar to the busbar then put one probe on neutral bar and one probe on earth bar. Testing L-N to Earth @ 250v this would would give an indication if there could be issues. I assume that is you were to do the same but do a continuity test it would also show if there was continuity between L+N to E thus indicating if any earth wire is touching live conductors. This would be particularly useful if it is a non RCD board. Hope that makes sense and I am right in my thinking. Your thoughts. Please I don’t want direct answers and be spoon fed but just pointers or clarification. I am keen to learn. In all honesty my current placement isn’t great and will be looking to move but give the current situation it’s hard. thanks [/QUOTE]
