I was doing a fuse board update the other day and normally I use duel RCD boards with mcb s but instead I used separate Rcbos due to the customer specifying these. I prefer fitting Rcbos due to just that one circuit is disrupted when there is a fault.
when quoting for the job I carry out a quick few tests which include a global L,N to earth to check for faults
then as I'm terminating the circuits on the day of the upgrade I carry out the insulation Resistance test on each circuit.
it then got me thinking can you carry out a global insulation test on the incoming tails like you use to be able to on Bs3036 boards
I haven't got my BGB with me at the moment it's at work but I'm sure that in there it states that RCDs should not be IR tested (plus they are sensitive to the test voltages) hence you can no longer carry out a global IR Test.
Im sure that you carnt carry out a global test anymore due to the RCDs /RCBOs but I just thought I would throw it out there and see if anyone has other ideas quicker ways to carry out insulation tests without having to do every circuit individually
