Blue Sea Systems 2718 Cover for MAXIBUS 2105/2126 - Clear Insulating

In this review of the Blue Sea Systems 2718 Cover for MAXIBUS 2105/2126 the bottom line is simple: this is a practical insulating cover for boat and solar wiring that prioritizes safety and easy installation. The reviewer found it most valuable for anyone upgrading or protecting a MaxiBus busbar assembly because the reinforced nylon base and clear polycarbonate top provide visible protection while meeting ABYC insulation requirements. It protects terminals for either the 12-screw 2105 or 6-stud 2126 busbar and adds mounting versatility with holes for the PowerBar 600A Common BusBar.

Key Features

• Compatibility: Works with the MaxiBus busbar that uses 12 screws (2105) or 6 studs (2126), so buyers can fit the cover to either mounting style without guesswork.
• Material construction: The reinforced nylon base gives a solid anchor while the clear polycarbonate cover lets you inspect connections without removing the cover.
• Insulation and safety: Breakouts and insulating design offer superior electrical insulation and meet ABYC insulation requirements for marine installations.
• Mounting options: Preformed mounting holes accept the PowerBar 600A Common BusBar, simplifying integration into larger power systems.
• Durability: The mix of reinforced nylon and polycarbonate resists routine marine wear and keeps fasteners and terminals protected over time.

Who It's For

This cover is aimed at boat owners, marine electricians, and DIY solar installers who use MaxiBus busbars and need a reliable insulating top that keeps connections visible while meeting ABYC standards. It is especially useful where grounding capacity and clear inspection are important, such as small craft electrical panels or solar combiner setups.

Those who need a decorative trim or a fully sealed waterproof enclosure should look elsewhere; the 2718 is an insulating cover designed for protection and inspection rather than complete environmental sealing. If your project requires a custom-sized cover or integrated breakers, this simple cover may be too basic.

Pros & Cons

Pros

• Clear polycarbonate top allows quick visual checks of terminals without removal.
• Reinforced nylon base provides sturdy mounting and resists mechanical wear.
• Designed to fit both 12-screw (2105) and 6-stud (2126) MaxiBus configurations for versatility.
• Meets ABYC insulation requirements, supporting marine safety standards.

Cons

• Not a fully sealed waterproof enclosure, so it does not replace a dedicated weatherproof box.
