I came across an interesting complaint recently. The regs says a circuit breaker should be legible and of the correct rating. On the coc i signed of I agreed to this but now one year later the KA reading is gone(i found on some older cb's you can rub all the markings off with your finger).
The question is , should you have a KA reading on a main 2pole cb as i found that you can buy a few makes of MCB's that has the KA rating in the paper work but not on the actual breaker itself?
and secondly, is there then an alternative to replacing the mcb just because the marking is not there ?
