Newmar AC-II Panel

The Newmar AC-II Panel is an essential safeguard for any vessel or RV operating AC power systems from shore power or onboard generators. After years on the water, experienced boaters understand that AC electrical safety is non-negotiable—especially in the marine environment where moisture and saltwater corrosion accelerate equipment degradation. This compact control panel delivers professional-grade protection without consuming valuable galley or cabin space, making it the standard choice for serious mariners who demand reliability over extended offshore passages and seasonal cruising.

At its core, the AC-II Panel features a double-pole master breaker that simultaneously protects both the hot and neutral legs of your AC circuit—a critical design that prevents partial power conditions that could damage sensitive electronics or create shock hazards. The integrated power-on indicator light provides visual confirmation that AC is energized, while the reverse polarity warning light alerts you instantly to wiring faults that could destroy 120V appliances or components. This dual-indicator system means you catch electrical problems before they propagate through your vessel's distribution system, saving thousands in potential equipment loss and ensuring crew safety in all conditions.

The Newmar AC-II Panel is ideal for cruising sailboats, trawlers, cabin cruisers, and RVs where reliable shore power and generator integration is fundamental to comfortable, extended voyages. Its lightweight design (1 lb) and compact footprint make retrofit installation straightforward in existing electrical cabins or new-build systems. Whether you're docking at marinas worldwide or relying on your onboard generator during remote anchorage, this panel integrates seamlessly with Newmar's proven power management architecture and works in tandem with battery monitors and inverter systems to maintain safe, stable AC distribution throughout your vessel.
