It does get loud at RC shows with lots of trucks running around.

Not sure if they make small versions but on the 1:1 machines I work on, some are equipped with auto reset breakers. Those would be perfect for you.

You are correct I agree to that, it sure can be noisy when out in the 'field' and it could be difficult hearing the buzzer.

I guess a auto reset breaker will be the thing to go for), and forget about any alarm. I see now that my breaker must not be larger than 2 amps, and I managed to find some auto reset ones with this value, where they sell parts for scale trains. After being tripped, they need some time for cooling down to reset, I don't know how long.
