Hiya everyone,
Just a quicky. I know Ohms law and calculating your cable size and protective device etc. But how do you know the cable size of a piece of cable visually around your home ? I can see a shower circuit and i can tell staright away its run in a cable much thicker than 2.5mm twin and earth. I am guessing at 10mm. But is there anyway of identifying cable size by sight like this ? Or is it a case of just becoming so familiar with the cable sizes on sight ?
cheers
