Blue Sea Systems MiniBus BusBar Cover for PN 2304 and PN 2305

This Blue Sea Systems busbar cover snaps over Common 100A Mini BusBar PN 2304 (5-gang) and PN 2305 (4-stud) to fully insulate the exposed terminals, satisfying Coast Guard and ABYC requirements for insulated positive and negative connections at a glance. It's the accessory to add when a bare busbar was originally ordered without its own built-in cover, or when retrofitting insulation onto an older installation.

Key features

• Fits Common 100A Mini BusBar PN 2304 (5-gang) and PN 2305 (4-stud)
• Clear polycarbonate construction for at-a-glance terminal visibility
• Snap-on installation, no tools required
• Satisfies ABYC/USCG insulated-terminal requirements for exposed busbar connections

Adding this cover after the fact is a straightforward way to bring an older, bare busbar installation up to current insulation practice without replacing the busbar itself.

Because it simply snaps into place, it's just as easy to remove for future maintenance — adding or re-terminating a circuit — as it is to install in the first place. Keep it in mind as a low-cost addition whenever ordering the bare version of a compatible busbar, especially on boats that see regular hands-on wiring work near the panel or bus bar location.

Insulated terminals matter most in locations exposed to accidental contact — a bilge, an engine compartment, or anywhere tools or stray cable ends might brush across a live connection. A clear cover keeps that protection in place without hiding the terminals from a quick visual inspection during routine maintenance, since you can see the connection clearly through the polycarbonate without removing anything first.
