Circuit labels help make a marine electrical panel or fuse block easier to understand during use and service. Blue Sea has several different label kits that vary in shape, colour, quantity and intended panel family. Compare exact part numbers rather than assuming that any label set will fit every switch or fuse holder.

Match the label to the panel or fuse block

4215-BSS and 4217-BSS: Black square waterproof DC circuit labels for listed Blue Sea 360, battery-management, WeatherDeck and ST CLB product families. Choose between 30 and 120 pieces depending on the number of circuits and the label text required.

8039-BSS: Black rectangular preprinted labels associated with traditional metal control panels, ST Glass fuse blocks and Contura-style water-resistant fuse panels.

8217-BSS: A gray rectangular label set listed for Contura switch water-resistant panels and certain blade fuse-block applications. Match the original switch-panel label space before choosing it.

7870-BSS: A separate black-and-white rectangular set aimed at emergency-vehicle circuit identification. It is not interchangeable with the marine panel label kits simply because the quantity is larger.

Fitment check: Confirm the actual panel or fuse-block model, label size, colour and printed circuit wording. These labels do not replace electrical circuit protection, correct wiring or manufacturer circuit diagrams.

How the package quantities differ

The 4215-BSS and 4217-BSS share the black square label family but include 30 and 120 labels respectively. The 8039-BSS is a 120-piece rectangular black set, while the 8217-BSS includes 60 gray rectangular labels. The 180-piece 7870-BSS is a separate emergency-vehicle-oriented set, not a larger version of either marine label family.

Before applying labels

Verify the function of each electrical circuit and use the correct preprinted identification rather than relying on old or ambiguous markings. Clean and dry the mounting surface as directed by the label manufacturer. Test equipment operation only using appropriate electrical safety procedures; do not work on energized circuits unnecessarily.

For the equipment the labels may identify, compare our Blue Sea marine switch-panel comparison, individual push-button switch guide and Blue Sea fuse-holder reference.

Common questions

Are 4215-BSS and 4217-BSS the same size?

Both are listed as black square DC label sets for the same product families. The main catalog distinction is the number of labels: 30 versus 120. Check the actual label sheet text and the panel requirements before ordering.

Will a larger 180-label kit work with every marine panel?

No. The 7870-BSS set is identified separately for emergency-vehicle circuit labeling, not as a universal replacement for marine panel kits.

Can I use a gray rectangular label set on a black square label position?

Do not assume so. Match the panel's label opening, its surface design and the intended circuit identification.

Can I arrange a pickup in Kelowna?

UsedRVParts offers viewing and pickup by appointment. Confirm the selected item before visiting.
