I was asking if the RCDs are switched to the off position during insulation resistance test, as I know they are sensitive equipment.

On IR test can u just switch RCDs off or do u actually have to dis them.
On a continuity test on existing lighting circuit, do all bulbs have to be removed, what if there is to many or some can’t be reached.

Sorry I’ve looking at this in the wrong way , the SPD is after the main switch and is pre wired , no need for over current protection , think I’ve got that now

When SPD is after main switch and is pre wired , then the is no current flowing through it , am I correct .
in LVE , SPD is before main switch

In the LVE board it’s before main switch, I’m trying to understand this and the way it’s wired, it appears to be wired before the main switch aswell.
Sorry I meant a LVE board , I’ve seen a LVE board with surge protection already installed in it , the SPD is before the main switch in this board , this got me confused.
