Review: Great product - Perfect fit and functional. Solved the problem ! Great value.
Review: 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 🙂

## Questions & Answers

**Q: Would this help prevent the spark when you connect a battery to a ebike? Please help thank you**
A: No. You need a switch in series that's rated for your application (current/power).

**Q: Can you vet a face cover with it**
A: They come with a rubber button cover. not sure if thats what you are asking

**Q: Will they work in a '95 Peterbilt 379?  Thanks in advance.**
A: As to electrical compatibility, these are spec'd to 50vdc.  I guess you are either 12v or 24v so you'd be good to go. Regardless of voltage breakers are current devices, so these will trip at 30amps. 

Physical mounting position is up to you

**Q: Does the push button also function to manually open the circuit? Or only to reset and close the circuit?**
A: it is a reset only.  No way to manually open the circuit.
