## Questions & Answers

**Q: What size ring connector is needed to attach wire to terminals?**
A: They are #8 as described in the description. Hard to find #8 rings in heat shrink connectors. #10 worked just fine for the terms and it seems all manufacturers sell this size.

**Q: Can I run +/- from batt to 100 amp breaker then +/- to fuse box so I can kill power to fuse box?**
A: Yes you can.  The fuse box will be powered off breaker.  I used a toggle switch panel instead of a main breaker.

**Q: Product page says this can handle 100 amps per block, does that mean 100 amps on the left 6, and another 100 on the right?**
A: No, it means 100a peak draw for the entire block...30a peak per circuit.  The main positive in should be fused at 125 per the specs from BlueSea.

**Q: Does this block come with a positive and a negative bus? I don't want to have to daisy chain the positive lead to each lead on the panel...**
A: Yes, it does indeed come with both a positive (fused) bus and a negative bus. Very nice unit, as with all Blue Sea products. I would and have bought again after purchasing mine.
