Use this panel for uncomplicated management of 3 battery banks - 1 House and 2 Start - in twin engine boats. With two On/Off/Both battery switches, each engine Start circuit is isolated from the House circuit, reducing the chance of fully discharging all battery banks at the same time.

Performing the same operations as three On/Off battery switches (one for each bank), the engine and house battery switches are both turned On when the boat is boarded, and both turned Off when leaving the boat. This minimizes the opportunity for error. In an emergency requiring that both batteries be combined - say a discharged start battery - simply turn the switch knob to the Combine Batteries position.

The 8689 also features a high amperage main DC breaker with 3 empty DC branch positions for user customization, as well as 24-hour DC branch circuit protection. Three unswitched (always on), push button reset-only circuit breakers provide protection for items like bilge pumps or alarms that need to be on 24-hours a day.
