I am going to place a 12 way Blue Sea Systems Fuse box behind my furniture, fed from a 16mm live flex cable. Is it better to buy one with the negative bus bar built in, or a waste of money considering the other option is just to run the negative 12v cables from each device to the nearby ground point in the rear of the van, and the negative from the blue sea box pictured below, would have to go there anyway?
