Get your AC or DC wires shipshape with a 2 stud and 20 screw terminal bus bar. This Blue Sea Systems bus bar is the industry standard and is a great way to organize and distribute power. Either behind the breaker panel or in the engine room, a bus bar can turn a spaghetti bowl of wire into something more organized and easier to troubleshoot. Use them to distribute the power from a single breaker to several loads; examples being navigation lights or cabin light circuits. They also provide a way to connect and disconnect wires as is required to un-step a mast; a must for sailors in the Midwest and New England. Sized to match the current loads, make sure that the bus bar you choose will handle the required amperage, plus some room for expansion.
