Have noticed my shower is wired to the non-rcd protected half of the CU - is that OK?...if not, why would it have been wired so as there is space on the RCD side.

It is not correct

It might possibly have been wired that way because it has a fault on it and someone thought avoiding the RCD tripping would be less trouble than fixing the fault :rolleyes:
 
There is no regulation stating that a shower has to be RCD protected, so it's not strictly a problem. If you are worried get a spark to check it or move it across. I personally always protect showers and most sparks I know do too.
 
Check with the maker. Some say that RCD is required.
Per the above I always install RCD in places where water, electricity and people mix.

I always put showers on the rcd side too. The point I was making was that it is not strictly incorrect. There may be an earth leakage problem which caused the rcd to trip, or the spark may have just put it on the non-rcd side because he always does. I'd move the breaker to the rcd side.

Or use an RCBO.

So I can use a RCBO as a replacement for the current MCB on the non-rcd protected end of the CU?...would be an ideal solution...don't fancy trying to re-route the shower cable across; it's like spaghetti in the CU!

It is a 9.5kW shower on 10mm cable - what rating RCBO would I need, and how much do they cost?
 
What brand names are in your CU and MCBs?


Hooray, the RCBO enthusiasts are taking over the world!
