Just a quick question really - is 6mm cable sufficient for running a 10.8kW shower?
I have replaced a 6kW electric shower with a 10.8kW one. I have replaced the breaker in the consumer unit and upgraded it from a 32A to a 45A. I have checked the isolating switch (pull cord thing) and it is set at 45A. The cable runs from the shower to the pull cord isolator, into the loft (insulated) then down a conduit to the consumer unit (no more than 10M of wiring at MOST) - I have installed it all but a friend advised that 6mm cable won't do... is he right!?
How hot will the cables get!? And: will the MCB trip before anything dangerous happens (if it should happen!)?
Thanks for your help
