What Are Bus Bars?

Bus bars are used to distribute the flow of electricity and act as a wire organizer to simplify the wiring process. Connect the bus bars to your leisure batteries and all downstream devices to the bus bars. This makes your wiring cleaner, safer, and easier to maintain, as opposed to wiring all devices directly to the batteries.
