## Questions & Answers

**Q: Any info on how much torque should be applied to the bolts?**
A: You only want to torque enough to flatten the split washer. Otherwise you might strip the plastic base.

**Q: What size are the Acorn nuts?  M6 or ??**
A: They are the same size as the posts, so 5/16” or 3/8” depending on which variation you purchase.

**Q: Do you mean 250 amps per post or the entire buss bar?**
A: Each post is tied together with the contact plate, so the 250 amp rating is for the entire bus bar. Sorry for the confusion.

**Q: How do you connect this to the battery?**
A: You will need to purchase loop terminals and wire of sufficient size to handle the amperage. Most recently, I used these as part of a system which needed to be assembled and disassembled, quickly. Also, my system did not draw more then 25A; therefore, I used BUNKER INDUST 50A 6-10 Gauge Battery Quick Connect Disconnect Wire Harness Plug Kit, and large gauge wire, with loop terminals connected to the studs in the distribution block.
