Why dont you just remove the immersion switch and replace it with the RCD?

Re the fuse size, what fuse does the whirlpool manufacturer specify?

pump is 1.2hp is 5A ok for this?

is it ok for rcd to be only means of isolating(except for mcb at board)

Re the fuse size, what fuse does the whirlpool manufacturer specify?

There should be a rating plate that states the current requirements. Or in the instructions. AFAIK 1.2 hp is about 0.9KW = 4 amps so you'd need a 5amp fuse but you would also have to think about inrush current.

Yes the RCD is a double pole isolator so that is fine as the only switch.

rating plate says I 1 is 4.0A so I will go for 5.0A fuse

many thanks
