A 20A 2 pole breaker has a load of 40 Amps line to ground on one side only. What amount of time should the breaker trip at twice it's rated load?
Several seconds is expected to reduce nuisance tripping on motor-start-up loads, but what would be considered extreme on the high end?
How fast would a 20A fuse blow under 40 Amps?
A time delay 20A fuse under 40 Amps?
At what percentage should a breaker trip within one minute? 120%? 150%? 200%?
Is there any info out there that may give me the data of what UL expects from a breaker or fuse?
