Worked to add additional protection to my custom generator cable.
I built a generator distribution cable to get all of the power my generator can output into the house during an outage. My dilemma is my generator is breakered for 30amps and the GFCIs are 20amp. GFCIs don’t trip on overcurrent so I needed these to make sure that only 20amps can go to the GFCIs. These breakers worked perfectly mounted in holes I drilled in the electric box. The waterproof domes are a nice feature. I don’t expect my breakers will ever get wet but the covers will also keep grime and dirt out. I haven’t load tested these but I have no reason to believe they won’t work. Overall quality of these breakers is adequate and everything you need to make connections is included. Happy with my purchase 🙂

Generator breaker
Replaced breaker on emergency generator. Better than original.

It’s a circuit breaker.
Measurements in the listing were accurate and everything worked exactly as expected. I needed to find some lock washers (which I had on hand) since this was going into a generator where the vibration would’ve loosened everything without that addition but no big deal. VERY prompt shipping. I’m just puzzled why the old one failed — it was barely 6 years old and this only gets used very intermittently. I hope this lasts!

Exact fit
The circuit breaker fit my Champion generator perfectly. Same size screws as the one it replaced, so the generator's wiring did not need to be modified.
