Designed to be used as an add-on fuse panel. Can be used with either "Hot" or "Ignition Controlled" circuits.
You must have some automotive electrical knowledge to wire/install it.
I used to design and build custom automotive wiring harnesses for race cars and street rods. From the Summit picture, the fuse block they use looks identical to the custom Delco bolt-and-stack block I have used in the past.
