I don't know why you keep saying left and right...the picture I see has "top, middle, and bottom"....

The long silver bar on top is the negative bus. You connect the neg battery and all neg (should be black) accessory wires. [ in the picture, they have incorrectly connect +12v to this bus bar]

The long silver bar on the bottom is the positive bus. You connect the +12v feed from the battery (usually RED). IT SHOULD BE FUSED AT THE BATTERY. And I think in this picture the wire is not heavy enough to feed an accessory bus. That depends on what is connected and how far it is from the battery.[ in the picture, they have incorrectly connect negative battery to this bus bar]

The LOADS in this picture are the orange wires. They should be connected to the middle screws. In that way, they will each get power thru their own fuse.

In this picture, none of the loads are fused. They are connected directly to +12v. The fuses in this picture are not being used at all.
Because they have the +12 and neg bus bars reversed, the fuses will never have power because they are connected to a Negative bus.
It cannot be more wrong.
