## Questions & Answers

**Q: is this good for 240V?**
A: No, you need Q230 30-Amp Double Pole Type QP Circuit Breaker

**Q: The product information says 14 gauge wire. Are there any of this type of breaker that will accept 12 gauge wire?**
A: Breaker will accept 12 gauge wire. Will accept (1) 14 - 6 gauge wire, and 12 gauge falls between this range.

**Q: Will this work in a square D Box?**
A: Check the other breakers in the box. They should have a type indicator on the other breakers in the box. The newer square D boxes use homeline type.

**Q: Can a Seimens breaker be interchanged with a Square D?**
A: Hi Elizabeth, No I think the outside dimensions are completely different. I'm not an electrician and went to Home Depot for their advice and I think if your other breakers are Square D then you must use another Square D breaker.
