Breakers
Once you've tripped those 30 amp. thermal devices a number of times, they seem to trip at lower and lower currents. This comes from past experience with the devices. I think the continuous heating lowers the spring rate that holds them in the closed position. We keep a good supply on hand and throw them away after a series of trips and we never reuse last years.
Just a thought!
