Last couple of kitchens I've done (16th Ed regs), I put two rings
into each, one RCD protected for the accessible socket outlets,
and one non-RCD protected for stationary/fixed appliances such as
fridge, freezer, oven, boiler, etc, which you don't want sharing
an RCD with anything else, and don't merit one themselves.


I made sure my boiler was on an RCD protected supply. I want volts off ASAP
if there is a water leak.


The problem with this is if something else trips the RCD whilst
you are away for a few days, and the house freezes as a result
of having lost its frost protection, then you could have a house
which is substantially written off by a water leak.

If it has an RCD, like the fridge or freezer, it's a bad idea
to share it, and none really merit a dedicated one. Having said
that, I have a boiler on a dedicated 10mA RCBD, but that's because
it's in the bathroom (and I had several spare 10mA RBCOs;-).

Why /do/ they always put the electrics /under/ the water parts in boilers?


The bottom is cooler, and they don't think much about minimising
the cost of repair when designing boilers.
