Blue Sea Systems AC Insulating Cover, 1 Module

Overview

The Blue Sea Systems 1331 is an AC insulating cover for one module in a compatible Blue Sea Systems panel. It isolates 360 panel AC components and circuits from DC system elements, helps meet ABYC safety requirements where AC and DC loads share the same panel area, and adds mechanical protection when the back of the panel extends into a locker.

This is a modular cover piece that works with interlocking SIDE, TOP, and END sections, so the enclosure can be built around larger AC components when needed. Wire breakouts allow cable runs in any direction, which helps when the wiring path has to turn quickly behind the panel or space is limited.

Key features

• 1-module AC insulating cover for compatible Blue Sea Systems panel layouts
• Isolates 360 panel AC components and circuits from DC system elements
• Meets ABYC safety requirements for panels with combined AC and DC loads
• Adds mechanical protection behind panels that protrude into lockers
• Interlocking SIDE, TOP, and END pieces can be stacked around larger AC components
• Wire breakouts allow conductor access from any direction

Compatibility and fit

This is the 1-module version, so fit depends on the panel layout it is being used with. It is used with compatible Blue Sea Systems AC panels across selected 120V, 230V, and 120/240V configurations, including source selector, ELCI, and main plus branch layouts. Matching the panel model is the right way to confirm fit before installation.

Installation and use on board

This cover makes the most sense where an AC panel is mounted against a locker, liner, or service space that can be reached from behind. It creates an insulated barrier around the back of the panel while still leaving room to route conductors through the breakout openings.

It also makes practical sense on boats that carry both AC and DC circuits in the same electrical area and need better separation between those systems. That is common on cruising boats, workboats, and larger center consoles where panels are often installed in tight interior spaces.
