Triple Battery Bank Management/DC Distribution Panel - 300A m-Series Battery Switches

Use this panel for uncomplicated management of 3 battery banks - 1 House and 2 Engine starting batteries - in twin engine boats.
With two On/Off/Both battery switches, each Engine 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 two batteries be combined - say a discharged engine battery - simply turn the Engine switch knob to the "Combine Batteries" position to combine both starting batteries. Additionally turning the House switch to Combine Batteries will add the House bank.

The 8689 also features a high amperage main DC breaker with 3 empty DC branch positions for user customization, as well as three circuit breaker protected 24-hour DC branch circuits. These 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, as well as for digital clocks and other electronics with programmed memory or pre-sets which are sensitive to loss of electrical power.
