Overview

The Blue Sea Systems 8030 is a basic 30-label set for DC electrical panels, fuse blocks, and breaker panels where clear circuit identification matters. Each label measures 1.438 x 0.438 in. (36.51 x 11.11 mm), which matches Blue Sea large-format label positions used on ST Glass fuse blocks and several DC panel layouts.

This set covers common onboard circuits such as bilge pump, blower, GPS, VHF, radar, refrigerator, running lights, stereo, and water pressure, along with a spare label for an open position. The reinforced weatherproof material is a practical step up from handwritten tags when a panel lives in a damp cabin, a cockpit console, or any other area that sees regular service work.

It suits boats that need a cleaner DC panel layout without changing the electrical hardware itself. For refits, seasonal maintenance, or finishing a fresh panel install, it helps crew and technicians identify circuits quickly when switching loads on and off or tracing a fault underway.

Key features

• 30 large-format DC labels for common marine circuits in one set
• Individual label size of 1.438 x 0.438 in. (36.51 x 11.11 mm)
• Used on Blue Sea Contura Waterproof Fuse Panels, ST Glass fuse blocks, and raised rocker or toggle circuit breaker panels that accept this label format
• Reinforced weatherproof label stock for panel areas that see moisture and regular handling
• Includes common legends such as bilge pump, GPS, VHF, radar, refrigerator, running lights, stereo, and water pressure

Compatibility and fit

This label set is meant for Blue Sea large-label positions, not every generic label recess on the market. It is commonly used with ST Glass fuse blocks and with panel families such as the Contura Waterproof Fuse Panels, including layouts like the 8053 and 8054. It also fits raised rocker and toggle breaker panels that use the same large-format label size.

Before ordering for an older panel or a mixed-brand electrical system, check the label window size and compare it with the 1.438 x 0.438 in. format. That matters most when you are replacing older labels rather than installing on a panel that originally used this series.

Installation and use on board

This set works best once the panel layout and circuit assignments are finalized, so each label matches the actual load on board. That is especially useful on cruising sailboats, center consoles, and small powerboats where navigation lights, pumps, electronics, and cabin loads share the same DC distribution area.

Clear labeling makes day-to-day operation easier and cuts down on confusion during troubleshooting, winterizing, or handing the boat over to a new owner or technician. On a working panel, that kind of clarity is often what separates a quick fix from a long search behind the helm.
