RCD spur

[Ionkontrol]

Hi,

Have looked at previous posts but couldnt seem to find the necessary info.

I have a my combi boiler and separate timer in a cupboard in my bathroom.
They are wired into a FCU single fused spur socket. I wish to add underfloor heating and as this is only supply, connect it to this. The consumer unit is fuse cartridge, so I would need to add an RCD. Can I replace the fused spur in the cupboard with an a double RCD and run all three off it, like this one.....

The underfloor heating is 600w, 2.6amps.
Boiler and Timer are negligible.

Thanks

It is not allowable to fit any plug/socket arrangement in a bathroom.

The boiler is not negligible, it has a 3A fuse.

I am assuming that there is no rcd protection to the circuit at present, and that Ib does not exceed 13A.

You could feed both appliances from the same cable by fitting an RCD spur to the existing cable with a 13A fuse, then feed the two appliances from the load side of the RCD spur, each with their own FCU and appropriate fuse.

What size fuse do the UFH manufacturers recommend?

From their info...

"Install the RCD
You must install a dedicated RCD or use an existing RCD. You may wish to use a combination fused-spur/rcd. No more thatn 4.8kw of heating may be connected to each 30milliamp RCD."

It says that you should "test it with a 5amp plug prior to tiling over it"

Is there such a thing as a double FCU RCD?

An RCD fused spur is only good for 13A.

It's WarmUp?

No, no such thing. If your load does not exceed 13A, you don't need 2 RCD spurs.

As I said before, use one connected to the cable you are using to feed the equipment, then connect two spurs to the load side of RCD spur, each one feeding one appliance, with the spurs fused down appropriately.

Yeah, it is a Warmup.

Thanks for the help

Why assume a 20A RCD?
