Product Overview

Organize or expand your electrical system safely with a DualBus Plus bus bar

Many boats come equipped with electrical panels sized to the needs of the boat without room for expansion. Furthermore, ABYC standards limit the number of wires that can be connected to a terminal to four. Often, finding a safe way to expand your boat’s electrical system is challenging. Blue Sea Systems has a solution. The DualBus Plus bus bar combines negative and positive buses onto a single block and adds a snap on cover to meet ABYC and USCG insulation requirements. The compact bus provides a way to power and organize five additional circuits. Negative and positive tinned copper bus bars ensure the best possible conductivity and are able to withstand the torque required for the best contact.
