Supply for Combi Boiler - RCD required ?

[Dave OCD]

Allright chaps

I have to connect a new Combi this Saturday morning, intending to fit a 3 amp fused switched FCU and take the supply off a handy socket [about 2 feet away and on a RFC not a spur]

The consumer unit is an old MEM with cartridge fuses and there's no RCD, [TNCS system with Ze of 0.14]
Now assuming the owner doesn't want a new CU [yet anyway] would you be happy to connect up as is or would you fit an RCD spur ?
I have an opinion but just wondered what other people might think ?

Why not, not regs, just curious?

Not many plastic ones left. And not many metal ones available!

Only because you don't have to until Jan 1st, it'll be easier and quicker [tight for space] and done properly I'm confident it won't catch fire. :wink_smile:

I've been fitting them for a while now. Although it's not compulsory until January it's in the regs now.
You may be confident of your work, but what if a component broke down and caused a fire, you may find yourself explaining why you chose to ignore the advice of the IET boffins on this and trying to prove that you know better.

I understand what you're saying Andy, but if we're going in to legal scenarios you said it yourself - it's not compulsory yet.
Honestly I must have installed 300+ dual RCD boards and haven't had any issues yet, and although made of insulating material I don't fit crap.

Cool. It's not correct though.

Sorry my mistake. I've just read the Wiring Matters from the IET regarding amendment three and the supervised or skilled person has been removed meaning that all installations require rcd where necessary. You used to be able to omit in some scenarios if the installation was under the supervision of a skilled or instructed person.

The skilled or instructed persons exemption applied to socket-outlets being used by ordinary persons whilst supervised, and for cables concealed in walls.
The requirement now is to provide RCD protection for all socket-outlets intended for general use, and for cables concealed in walls run in prescribed zones and not provided with another acceptable method of additional protection.
