## Questions & Answers

**Q: What size Ring terminal do i need and what is largest awg it will accept?**
A: The main supply and ground studs are 1/4x 20.  I ran 8 ga wire to these with  no issue.  The individual circuits are  #10 for the ground and #8 for the hot.  I ran 12-16 ga wire to these, depending on the amount of distance the circuit covered.  If you're neat, you could run 12 to each one with no issue.  10 ga might push it al little, but  could be done.

**Q: Is there a pdf instructions like on the other ones i can download? all i see is a video.**
A: I don't know about a pdf, but the back of the package has simple directions on it. Basically on the top of panel you connect your ground and bottom you connect your power. I found this product on a YouTube site called Tiny boat nation.  I'm very happy with my result.

**Q: Is the first power wire from battery positive and then the Second terminal a trigger wire to enable the other fuses to be turned on?**
A: This is a fuse panel intended for marine applications, and they should always be wired directly to the battery. What you are referring to is an automotive type of application, with an "accessory" side, which comes from the battery, via a relay, to a fuse pannel. You can wire this up any way you please, just do it correctly.

**Q: Would this be good on a Honda pioneer to run led lights and a winch?**
A: Well you could use it for that but both the lights and winch should come with there own relays wiring and switches the winch would. Be the one item I’d tell you not to run to this fuse block just because of the amount of power needed to run it . This is great for adding lights stereo led whip lights 12 volt usb ect.

After having bought two of the cheaper ones on Amazon at 1/3 of the price of this, I finally decided to risk the £40 and see what it's like, intending to replace one of my existing fuse boxes. I am not disappointed. The quality of this unit shines through and I have immediately ordered another to replace the other cheap one.
