Review: Work like it should no problem 😊 - Good product 👌
Review: Perfect fit - I punched in the stats for the circuit breaker and this popped up. It arrived the next day, and looked exactly the same as the old one and even had a new washer indicating a reset button…which was a nice touch, seeing as how the old one had worn away years ago.

## Questions & Answers

**Q: Can this replace 3.2 amps 230v - 50/60hz?**
A: I would not replace a 3.2 amp with a 20 amp.  It may not protect whatever component only wants to see 3.2 amp.

**Q: The specs for this 10 a breaker says current 3-50 a; rating 10 a. i thought that the circuit breaker would open over 10 a ? 50 a is too much!**
A: It's rated at 10 a for ac

**Q: Will this work in a predator 4000 watts generator replacing the 13amp breaker**
A: I am not 100% sure, but I don't see why not.  It's pretty close in specs, so should work.  The 15Amp max is a little above your 13Amp, therefore if you have 15Amp wiring, breaker, etc., it should be okay.  But that's only my opinion.

**Q: diameter of mounting hole required? it seems this was asked but no tangible replies...**
A: 3/8" hole
