Here's the situation: there is a 100 amp 3 phase circuit feeding a 70 amp continous load through #2 conductors. The load is an oven so its either on or off, 0 non continuos load. The conductors are good for 130a and 90 amps is 125% of 70 so the 100 amp breaker should be good to go but it gets hotter than i like. I havent actually measured the temp but it is not comfortable to hold your fingers to it for very long. My breaker house says it's normal but i want a second opinion. The breaker is a GE snap in.
