Product Overview

An AC panel that manages power from two sources

Blue Sea Systems traditional metal breaker panels have been installed in boats for years. They have become the standard for reliability and design. A wide variety of breaker styles and ratings make these panels an easy choice for most electrical systems.

This panel is best suited as an AC Main panel for applications with two power sources. It comes pre-wired for easy installation with hot, neutral, and safety ground bus bars already installed. Two A-Series 50A double pole main breakers are pre-installed and include a sliding lockout to prevent both switches from being in the ON position. AC Power from a genset, inverter, or shore power source, when combined creates a very dangerous situation. The slide lockout ensures that power sources remain separated. Both breakers combine switching and circuit protection and are trip-free and cannot be held in the ON position when a fault is detected. A red LED reverse polarity indicator light warns if polarity is switched. A green LED at both positions indicates switch is ON. Large format labels are backlit for visibility in low or no light conditions. Included are 30 commonly used AC labels and 30 commonly used DC labels.
