AC Wiring

Gary and his boys are getting after the re-wire project.  I'd say 75% of ac and dc wire has been pulled to final destination points.  The distribution panel is in as is the battery selector switch.  The shore power outlet is installed on the starboard side of the house top at the sternmost end

The Mastervolt 2000/100 combi (inverter/charger) is also in place under the foot of the pilot berth on the starboard side.  There is some question regarding the need for an external shore power/inverter selector switch. The Mastervolt documentation indicates that the inverter has an internal transfer switch for this pupose. There should be no need for another.   

There is not that much to the AC side of this boat.....three AC outlets on one breaker, another on a separate breaker dedicated to the Contour 750 watt microwave, the 5000 BTU Climma air condtioner/heater,  the Sonicview 17 inch computer monitor and the Allcraft 9 gallon water heater.  Everthing with the exception of the water heater (including the air con) will run off the AC current provided by inverter.

There are two AC outlets from the inverter, the "Short Break" and the "Power". All appliances that can be powered from the inverter should be wired from the "Short Break" side; those that require shore power should be wired from the "Power" side. The water heater is the only appliance that has to run off shore power and should therefore be wired to the "Power" side; everything else goes on the "Short Break" side. Dip switches can be set to "generator support" or "power support" but not both. I will not have a generator so my preference is "Power support". ( I may carry a small honda generator but only as emergency backup to charge a dead engine start battery or run a drop light or two.)

Will post some photos later this week.
