Discuss rotary isolator in the UK Electrical Forum area at ElectriciansForums.net

…….Might see if i can get some 3.5mm.

But seriously its a bit of a run so it's going to be 4mm SWA.

I still can't get over their 25A mcb business, Are they commonly stocked?

Will 4mm be big enough if it is a bit of a run?

What is there to get over? Most decent manufacturers offer a 25A mcb
 
Yea i checked out 'tlc' and a couple of other online shops which only displayed the 'standard' rated mcbs. I can't think I've ever come across a 25A mcb. Perhaps it's the 'go to' mcb for air con units!

That depends on the size of AC units, I have been wiring quite a few up recently that are rated at 12 amps.
 
Here's a 40A isolator i fitted today when I put a 32A circuit in for the hot tub.
