grounding accessories

[toddman]

After hours of research, and a few beers. I still have a question about grounding accessories. I just purchased a 36-48vdc to 12vdc reducer,25 amp. My plan is to go from the reducer to a fuse box. (I am looking at a blue sea fuse box that has a ground on it.) My thought is to run all the accessory grounds to that fuse box. I am going to make a metal bracket to attach the fuse box to. My question is "Will this work, since the fuse box is attached to the bracket which is attached to the frame?" And from what I've read, your not suppose to ground anything to the frame.
