Function
The AC Master Control maximizes AC input capabilities.
This product automatically transfers loads from multiple
inlets and generators (maximum of 4 inputs) on 50 and
100 amp, 240 VAC electrical systems.
How does it work?
Within five seconds of turning on shore power with the
generator running, the AC Master Control will take the
generator off line and after a three second delay,
automatically engage shore power.
Benefits
• Simplifies the engine room eliminating slide bar controls
and additional wiring. Engine rooms with slide bar controls
need more wire harnessing, bigger panels and require the
boat owner to make decisions about power sources
• Eliminates inconvenient trips to the engine room to
decide which switches to move in order to ready the boat
for shore power vs. onboard power
• All switching is done automatically, eliminating the
possibility of crossed connections

Function
A/B Selectors automatically sense the location of the power source:
port, starboard, fore or aft. The unit selects the AC connection and
locks out a second power source. Units both electrically and
mechanically lock out a secondary source. 9R units feature a fiberglass
housing that does not need to be grounded.
Benefits
• Eliminates live unused inlets, eliminates possibility of crossed
connections
• Interlock controlled contacts ensure proper connections
• Eliminates the need for manual switch gear such as rotary switches
and slide bar lock outs; all switching is done automatically
• Eliminates inconvenient trips to the
engine room to change power sources
• Constructed of corrosion-resistant
materials for years of trouble-free use
