My dad wants to install a Winterwarm WWDF20N bathroom heater. As the heater needs to be fused at 13A, he was going to add this to the shower's circuit which has a 40A MCB protected by RCD, and is a 10mm radial circuit... Basically spur off 10mm, double pole FCU 13A, then 2.5mm to heater.
I would not have thought it would overload the circuit as the shower is the only thing connected to it, but I just wanted to check if it would be ok?
