## Questions & Answers

**Q: Can this be used as a solar panel 48vdisconnect? And can anyone link a panel that fits this breaker**
A: You need to get with the solar company, a breaker works as a disconect, you can do what you want if you own the boat. But you need to be a licensed marine electrician if doing work for someone else. (Fire ) is real problem on a boat. I'm not responsible for any thing said here

**Q: The breaker in the picture shown indacates 5amps, I am looking for a 30.**
A: They are 30 but I don't recommend - they didnt hold up at all.

**Q: Can this breaker be installed without a breaker box?  It looks self contained.  Thank you for your reply.**
A: yes as long as there is no exposure it will be fine.  you can use cantex box from home depot for about $5, you only need this box if there is any exposure to prevent any sparks or electrocutions.  please call ramsey if you have any additional questions at (310) 864-3131. thank you- ac dc marine, inc

**Q: Will this work on a onan microquiet 4000?**
A: Todd I don’t know for sure. I would imagine if your generator has female spade connectors and two small set screws that attach the breaker in the front it will be just fine. I installed them in an old boat for shore power, and they work fine. it has two 30 amp cords coming in so they take a ton of currant.

    works great
  

*by M***O on Reviewed in the United States on December 11, 2022*

used this to replace the breakers on my Onan generator. They fit perfectly, the only thing difference from my stock Onan breakers is the these have screw terminals and the Onan were flat spade, so I had to change the terminals on the wires, but no big deal.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice compact breaker
  

*by T***D on Reviewed in the United States on August 14, 2022*

Not much to say here - it's a circuit breaker. But it seems like good quality, and doesn't take up too much space.
