Hi I was wondering about how a 23kw 400v 32A electrical heater would be wired, e.g what mcb and what size cable?? With 32A commando socket.
From what I’ve learned in college, I’m a level 2 apprentice, when it comes to cable calcs the design current P/V=I that would give me 100A and the cable would have to be at least 16mm. Is this right ?
