Hi,

My current electric shower does say anywhere its KW rating. I intend to
replace this next week and am wondering if I can determine the rating from
either...

a) the rating of the circuit breaker

b) the size of the cable

c) some other means.

By looking at the cable I cant determine its size (mm2?) - is there a
measurement that I can take of it to determine its maximum rating. Also a
quick breakdown of cable size against shower rating would be most useful if
anyone can help.

Thanks in advance for any help,

CM.
