So, having read through this thread, does this mean that 6.00mm twin and earth is too small for a 8.5KW shower? And to protect the cable, a 32A mcb should be fitted?
A 40A mcb would exceed the current carrying capacity of the cable?
8.5KW at 230V =37A.
Current rating for 6.00mm twin and earth pretty much only seems to be complaint if the cable is clipped direct.
Given that most installations now contain thermal insulation to some degree or other, has 6.00mm had it's day?
