My heating contractor talks of a "Popper". As far as I can deduce, it's=20
a breaker in the form of a blade fuse like automotive. Probably in the=20
2-3 amp ratings.

What about when the circuit opens, a relay drops out, normal closed=20
contact closes, triggers a 555 timer with a sonalert buzzer, and an LED=20
strobe. Or program a small PIC to do the work. :)
