Do the RCDs wear out?
How can they be tested?

these things have been a pain in the arse for a long time. they trip
out all the time. it is is easy to link them out and bypass, i have
done this for many year and have no problem with tripping any more, do
it and save you all the bother of lights out etc.

I've yet to have a nuisance trip on my split load unit. If I had I'd
investigate why.

However, the lighting circuits do sometimes trip their MCBs when a bulb
blows. If this really is a concern they can be changed to ones which allow
a longer 'instant' overload. Or arrange the wiring so the hall and stairs
is on a separate circuit as I've done - that way a source of light is no
further away then than the nearest door.
