Hi guys sorry for posting as I know there is a lot of posts similar to this.
my problem Is for my trade test I am a little confused about insulation resistance test. I know most of it for example
lock off at main switch
remove all sensitive equipment
test between live-neutral live-earth earth-neutral
make sure results are okay.
the things im not sure of are when testing the whole board and it has RCBO's In it do I leave all RCBO's on and just disconnect earth and neutral links and test at main switch?
if testing individual circuit do I switch RCBO off and then again disconnect earth and neutral links and test at outgoing of RCBO? or do I also need to disconnect the wiring of the circuit?
I have also heard people speaking about disconnecting the main neutral why would this be needed?
thanks for any help.
