Why on earth would a breaker trip at 80%? Breakers (and fuses) trip at
100% or greater load, depending on the length of the overload. You can

Perhaps your British breakers do, not over here. It's a safety feature.

Simply not true. If you look at the trip curve the trip is typically
at 1.10% +/- 1.5%
