No problem, I will do that.
Turns out I have a spare 20a MCB on the RCD protected side running a radial circuit to a single unused socket. I will re-purpose this to become 2x FCU.
Combined maximum load (when on heat mode) is 2x 7.5amp = 15amp.
Thought if I could use just 1 of the remaining 2 MCBs it still leaves me with a spare.
I did toy with the idea of using RCBO's, but finding stock of a 16amp MK RCBO is proving difficult. I'd also still need 2x FCU with the RCBO...
Thanks Pete.

I believe I am right in saying I can use just one of the C16 MCBs to feed both RCD FCUs with 2.5mm twin and earth, one...
Thanks Pete, I think thats the route I will go down anyway - even if not specified by the manufacturer. I understand that only one of the MCBs needs to be used to feed both RCD FCUs, one spurred off the other.
Ok thanks, I will check the manufacturers documentation.
If it does not state I think I would prefer there to be RCD protection due to the fact there is power to the outside units. All cables will be surface mounted in conduit.
Hello,
We are having 2 wall mounted split system air conditioners installed. These come supplied with a 13amp plug which will power both the internal and external units.
I would like to wire these in for a more permanent and neat installation. Our consumer board only has a single "RCD...
