West Marine DC Parallel Panel (Emergency Cross Connect Panel) for dual battery bank management.

32V DC Parallel Panel with emergency cross connect key.

In good working order and ready to install.

This marine electrical power management panel is designed to isolate and control dual battery systems.

The top two rotary switches independently turn the House and Engine DC circuits on or off.

The bottom key-activated switch serves as an Emergency Cross Connect, allowing you to combine both battery banks to jump-start the engine from the house bank if the main cranking battery dies.
