Blue Sea Systems AC Isolation Cover, For Toggle Circuit Breaker Panels, Thermoplastic

Overview

The Blue Sea Systems AC Isolation Cover is an insulating back cover for Blue Sea Systems toggle-style circuit breaker panels where the rear of the panel needs to be shielded inside a locker, cabinet, or electrical compartment. It helps separate exposed AC panel backs from surrounding DC wiring and gear, which is especially important on boats where space behind panels is tight and service access is shared with other equipment.

This cover adds electrical insulation and mechanical protection for panel backs that protrude into storage or utility spaces. The cover material can be drilled for wire entry and exit, so installers can route conductors cleanly without leaving the panel back exposed. It is also listed for use where combined AC and DC panels must meet ABYC requirements.

Key features

• Insulates exposed backs of compatible AC toggle circuit breaker panels.
• Adds a protective barrier when the rear of the panel extends into lockers or other accessible spaces.
• Helps isolate AC components and circuits from nearby DC system elements.
• Cover material can be drilled for wire entrance and exit during installation.
• Meets ABYC requirements for panels that combine AC and DC circuits.
• For Blue Sea Systems toggle-style circuit breaker panels only.

Variants

This AC Isolation Cover is offered in two cover sizes for different toggle circuit breaker panel layouts.

The variants differ by position count and panel column layout. Both versions serve the same purpose: insulating and protecting the back side of compatible Blue Sea Systems toggle-style panels.

• 4031: Cover Size 10 Position. This version is the 10-position, 2-column cover and has a listed weight of 0.38 lb, or 0.17 kg.
• 4029: Cover Size 8 Position. This version is the 8-position, 1-column cover and has a listed weight of 0.24 lb, or 0.11 kg.

Compatibility and fit

This cover is made for Blue Sea Systems toggle-style circuit breaker panels only. It is not a universal enclosure for any marine breaker panel, so matching the cover size to the panel layout matters before installation. The 8-position version suits a 1-column layout, while the 10-position version suits a 2-column layout.

It is a practical fit for boats where AC and DC distribution share the same panel area, including cruising sailboats, sport-fishing boats, and powerboats with electrical panels mounted near lockers, cabins, or service compartments. The main benefit is not cosmetic; it helps protect wiring, panel hardware, and anyone reaching into the space behind the panel.

Installation and setup

Plan wire routing before mounting the cover so the drilled entry and exit points line up with the panel conductors. Keep the cover clear of strain points, sharp bends, and moving gear inside the compartment. After installation, the panel back should remain accessible for service while still keeping exposed AC components separated from nearby equipment and stored items.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
