FCU is a recipe for disaster. 20A D/P switch every time for me.
It was more to do with amp switchgears and isolation rather than cable sizeYou could use 1.5mm t&e with a 16a breaker.
Hi - Local 20A DP switch for immersion isolation is appropriate IMHO as work may be done in the vicinity by someone not familiar with boards etc. I use 2.5mm from the board as it has margin for installation Method 103 worst case.
If domestic no requirement for local isolation if on its own dedicated circuit.
What do the manufacturers instructions say? Or is this a theoretical question? Local DP switch for me also. If the voltage fluctuates that fcu will die. Seen it happen so many times. Also the local isolation helps Mr wet pants who’s either too stupid or too lazy to isolate elsewhere!
