120VAC Distribution Panel

Blue Sea systems has a nifty little web tool that helps you custom design electrical panels based on their Panel 360 system. The tool can give you a "preview" of what the panels will look like (not exactly but close, it does not show breaker amp rating and labels). Here are some ideas based on the latest electrical schematics. These panels should just fit in the planned spaces.

In summary, this panel provides the main breaker for the shore power, and three groups of circuits: one group full time shore power, two groups each selectable between shore power, inverter and generator.

From left-to-right, top-to-bottom:

  1. AC voltmeter measures shore power voltage
  2. AC Ammeter measures shore power current draw
  3. 50 amp ELCI breaker controls the connection to the shore power bus
  4. Four circuit distribution connected full time to shower power bus (battery chargers, AC heating assist)
  5. Shore/Inverter/Generator source selection for the four circuits to the immediate right (#6)
  6. Four circuit distribution source selectable by #5
  7. Shore/Inverter/Generator source selection for the four circuits to the immediate right (#8) 
  8. Four circuit distribution source selectable by #7
At this time, I cant think of anything else needed for the AC panel.
