A little late in replying but I had computer problem. I've got a
test jig of sorts for testing electronic repairs: 2 Amp circuit
breaker which states has a 3.5A carry, suppose meaning the circuit
breaker will trip if there's an extended time when the current is over
2 amps but allows an over-current situation (up to 3.5 amps) for a
short period of time (to allow power supply capacitors to charge,
Wondering if this somewhat applies to your situation: the sparking was
of a short duration, the carry period, so did not trip the breaker.
The spark was hot enough to melt the plastic.
(If I'm wrong I'm quite sure I'll be corrected and we'll both learn!)
