i've noticed that my built-in cooker is wired to a 50amp mcb in the c/u.i think the suggested size for it is 20amp.what effect if any will this have on the circuit protection
thanks for info,the make of c/u is dorman smith,100amp switch and im upgrading my shower from 7.2 to 8.5kw hence i have to upgrade the mcb as the existing one is a 32amp
