Used a 30A metallic inlet, a 120V AC Main-Only Toggle circuit breaker panel, a Marine GFCI Duplex Outlet, and a 30 amp power cord. Marine tinned #10 multi-strand cable joins the intake with the breaker box and #12 goes out of the box to the GCFI outlet. Used a Guess three-stage battery charger (cant see here) placed on tray strongly velcroed to floor placed to the right of the battery, behind the screwed on lid (bottom right corner of first picture). The charger is connected to the shore power directly via a power cord and plug so it can be removed if needed.
