Blue Sea Systems MaxiBus Insulating Cover 2719 — Clear Polycarbonate Top, Reinforced Nylon Base for ABYC-Compliant Protection

The Blue Sea Systems 2719 Insulating Cover protects MaxiBus busbars and mounted breakers/shunts with a clear polycarbonate top and reinforced nylon base for safe, ABYC-compliant insulation.

Keep exposed busbar terminals and attached components protected without hiding them from inspection: the 2719 insulating cover is built to fit MaxiBus busbars secured with either six screws (part 2128) or four studs (part 2127). Its transparent top lets you visually check connections while the reinforced nylon base and molded breakouts maintain electrical isolation and mechanical support. Designed with practical mounting points, it accepts 285 Series surface-mount circuit breakers and DC shunts so you can consolidate and safeguard critical DC distribution components.

How does the 2719 cover enhance electrical safety on board?

The cover reduces the risk of accidental contact and short circuits by enclosing busbar terminals and wiring terminations. Its reinforced nylon base provides a non-conductive mounting surface while the clear polycarbonate cover creates a physical barrier, satisfying marine insulation standards.

• Encloses live busbar terminations to prevent accidental contact.
• Molded breakouts route cables while preserving insulation.
• Material combination resists electrical tracking and mechanical wear.
• Meets ABYC insulation requirements for marine installations.

Can I mount circuit breakers and shunts directly to this cover?

Yes — the 2719 includes preformed mounting holes that accept 285 Series surface-mount breakers and standard DC shunts, allowing you to centralize protection and measurement hardware on the busbar assembly. This simplifies wiring runs and keeps protective devices close to the source.

• Pre-drilled bosses align with 285 Series breaker footprint.
• Shunt mounting points accommodate common DC current-sensing shunts.
• Shorter wiring paths reduce voltage drop and installation complexity.
• Clear cover permits status checks without removal.

Which MaxiBus configurations are compatible with part number 2719?

The 2719 insulating cover was designed specifically for MaxiBus busbars that use either the six-screw 2128 attachment or the four-stud 2127 configuration. Verify your MaxiBus model and fastener type to ensure a correct fit before ordering.

• Compatible with MaxiBus using 6-screw (2128) or 4-stud (2127) mounting patterns.
• Fits common commercial and recreational DC busbar layouts.
• Works with busbars that accept 285 Series breaker accessories.
• Clearances and breakouts designed for standard marine cable sizes.

Who is this for? The Blue Sea Systems 2719 insulating cover is aimed at marine electricians, boat owners, and system integrators who need a durable, code-conscious way to shield MaxiBus installations while maintaining visibility and access. It’s particularly useful when you want to mount 285 Series breakers or DC shunts near the busbar to shorten wiring runs and organize your DC distribution panel. If you require a rugged, non-conductive protective enclosure engineered to meet ABYC insulation guidance and simplify component placement, the 2719 is purpose-built for that role.
