The primary house electrical system is 24VDC with a step down transformer to provide for the occasional 12VDC loads. Shore power AC supply is 30A maximum, through an isolation transformer.
Shore power is supplied via 75 feet of three conductor 30A rated cable. The cable is deployed via a Cable-Master that stows the cable below decks when not in use.
The following devices are wired from the shore power cable connection to the main AC distribution panel in the following order:
- self-resetting GFCI
- 30A master breaker switch
- 30A isolation transformer
Primary house batteries are located in a compartment under the floor in the main salon. Two pair of 2/0 battery cable run from the battery box, aft to a main terminal block mounted on the bulkhead in the engine room.
Distribution DCD-100 switch modules are located in the following areas (each can switch up to ten loads)
- aft cabin (behind master berth headboard)
- forward salon, port side
- forward salon, starboard side
- engine room (one 24VDC and one 12VDC)
