Hi there,turns out what I am quoting for is an add on cooler for a ducted heating system which draws 38A .What is the maximum current 6mm can handle over a run of around 15m, inside conduit?

Calculations would say 44A for a flat 6mm 2C+E, in conduit, 15m long, at ambient temp. Obviously you can't get a 44A MCB, so you'd have to fuse it at 40A.

Michael, your questions suggest you may not be an electrician. If that is the case you'll need to sub the electrical install or to a licensed electrical worker.
