I'm in the process of designing a rewire for the house I'm buying (1950s big ish 3 bed semi) I've split most of the circuits over 2 RCDs (3 circuits on one, 4 on the other) but I have an additional three circuits that I believe should be non RCD protected. Freezer spur, UPS spur and submain to workshop/garage. Always worked with and trusted MK stuff for small power, so had a look at MK Sentry range but from what I can gather most of the twin RCD boards only seem to support 2 unprotected circuits. They claim to be fully flexible and what not, I can only assume the limiting factor is the unprotected neutral bar as you cut the live bar to suit?
Any suggestions on this? Probably obvious to anyone who's opened one before but they're a bit different to the boards I'm used to working on (I'm an ex industrial spark and now work for the DNO). Should I be looking at a different board completely?
I'd love to RCBO everything but my bank balance says differently! The other option I've just thought while writing this would be to wire the freezer and UPS as a radial out of 1 breaker which actually sounds like a decent idea but the red, sorry green, book probably says otherwise somewhere!
Oh and before anyone asks, I fully intent to notify building control etc with regard to these works.
I'd have loved to have just slapped up 20mm galv conduits everywhere but I don;t think the other half would agree!
