insulation testing rcd's

[markthebuilder]

hi
if you have seen my thredes you will know im working at improveing my instalation practice and currently testing my work (hell of a learning curv)

when insulation testing do i need to disconect RCD's .
pull the wiers) or just swich them of. i am refering to 30 mamp on a split bord if in the on position will conecting phase and nutral protect them and why
My geuse is 500v dc/2 =250 =within limets so what if tested at 1000v dc

in short are all rcd's voltage sensative

what are the implications of testing a domestic 230v ac with insulation test set at at 1000v dc

You should disconnect the voltage dependant type of RCD as their electronics can be damaged by IR testing. This type normally has a functional earth wire (cream).
For the good old torroidal RCDs it doesn't really matter.
The 500vDC IR test afaik is more to do with the peak value of the mains sine wave, DC to overcome the capacitive effect of the cable. I wouldn't bother the 1000v IR setting for 230v systems as it may lead to problems.
