## Questions & Answers

**Q: I am replacing a breaker with two studs coming staight out the back for terminating. Is that the case for this breaker? Need picture of the back.**
A: The terminals come straight out of the back and use 10-32 screws.  Here is a link to the Blue Sea dimensional drawing for the A-series breaker:  http://assets.bluesea.com/files/resources/dimensioned_drawing/7200-7230.jpg

**Q: Can i use this breaker to build a separate 20-amp circuit for my rv? i have a 30-amp rig and want to put in a second circuit (20-amp)**
A: I believe so, I used it in a 30 amp system

**Q: Are these available with a black toggle? whats the difference between an a-series and a c-series breaker?**
A: Yes the manufacture part number would be 7212 for the black toggle. Class A is the industry standard for circuit breaker toggle switches, and Class C is the more heavy duty version mainly the Interrupt Capacity is increased with the Class C series. In addition to that I do not believe that they make the 20A breaker in BLACK with the Class C. If you have additional questions I would recommend calling our tech line at 310-864-3131.

**Q: Do these breakers come with the LED indicators?**
A: Breaker only; no LED or indicators
