Get your AC or DC wires in shipshape with a 5 circuit or 10 circuit terminal busbar.

This Blue Sea Systems busbar is considered the industry standard and is a great way to organize and distribute power. Either behind the breaker panel or in a locker, a bus bar can turn a spaghetti bowl of wire into something more organized and easier to troubleshoot. They can be used 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 Mid-West and New England. Available covers help to prevent accidental contact and possible cross current shorts. Sized to match the current loads, make sure that the bus bar you choose will handle the job, plus some room for expansion.
