Newmar AC-II 30-Amp Master Breaker Panel

Description

The Newmar AC-II 30A Master Breaker Panel provides the primary control and protection point for a vessel’s incoming AC supply. It is designed for boats using shore power or an onboard generator and combines a double-pole main breaker, power-on indication, and reverse-polarity warning in one compact panel.

The 30A double-pole breaker disconnects both the hot and neutral legs of the AC circuit, giving the incoming supply a clear master disconnect. A power-on indicator confirms that AC is present at the panel.

A dedicated reverse-polarity light warns when the incoming wiring is reversed, a condition that can create a serious shock hazard and should be corrected before the circuit is used. Bringing this warning directly to the main panel helps make abnormal shore-power conditions immediately visible.

The panel requires a cutout of approximately 4 x 2.5 inches. For boats that need a compact 30A master AC panel with two-pole protection and reverse-polarity indication, the Newmar AC-II provides a straightforward shore or generator power control point.
