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
always run for 100% forever.

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%

"As you add up the electrical loads, keep in mind that a wire rated at
15 amps can carry 15 amps all day long. However, 15-amp breakers and
fuses can only carry 12 amps—80 percent of their rating—on a continuous
basis. Continuous basis is considered to be a circuit loaded to capacity
for three hours or more. This 80 percent rule applies to all breakers
and fuses."
