ABYC limits the number of wires on a single terminal to 4, which can make it difficult to add more electrical loads like stereos, fish finders and GPS. Install an easy access point to add future electrical appliances by pairing a DualBus Plus and a 6006 m-Series ON/OFF Battery Switch. The m-Series ON/OFF Battery Switch offers a method of disconnecting all loads from the battery for storage or in the event of a fire, while the Dual Circuit Plus™ will offer an insulated and compact termination point for both the positive and negative wires when installing additional appliances.
