would anyone know approximately what amperage might trigger the circuit breaker in a Z? Assuming it is working properly after 80 years. . . .
thanks!

Simple answer should be 14-15A, however being a thermal breaker it's also over a specific time period before it trips.

The test procedure is basically a dead short.
Bottom line, don't expect that breaker to protect much of anything. Even if it does work, you probably should consider external solutions.
thanks! Kinda what I was guessing.

The breaker will adequately protect the transformer as designed when it trips in 4-17 seconds into a .1 ohm load at 30 amps. The Z is rated at 14 amps continuous output, and the original Z-22 thermal breaker is rated at 15 amps.
