## Questions & Answers

**Q: The description and reviews are confusing. The specs say "push to reset operation", but I see only replaceable fuses. Which is correct?**
A: mine looks like a hard line fuse/non reset

**Q: Dose the fuse come with the block or do I order a 400amp sep.?**
A: Fuses are sold separately. The Blue Sea 400A fuse is on amazon - search for B000MMH1JO. Hope this helps.

A: The fuse is sold separately and can be from 225 amp to 400 amp.

**Q: Does this product come with fuses?**
