Hi all, I've been working at a swimming rectfying many faults. The one major fault was bought to their attention after a fire broke out in a breaker.

The problem is i cant see why. The breaker and main incomers can get hot to the point of fire. The load is 20.2A on 16mm cable, the connections are fine, i have made them my self many times.

The ciriuit is being ran from a 32 way board, its ran 0ut of ways so the last electircian used a new two way board plus main 65A over load 30ma RCD, split betweeen two 32A ring mains. The breaker gets hot in the midle even though i have replaced it. The incomers i didnt replace, i dont kmow why some used 16mm cable either and at a load of 20.2A is it getting hot. The cables are rather bunched but i dont believe this is an eddy current problem?

what was the problem.....breaststroke or paddle?
