Overview

The Blue Sea Systems 8037 is a circuit breaker panel plug that fills an unused standard toggle circuit breaker hole in a panel. It comes in black and is sold in a pack of 6, which makes it useful when you are cleaning up a refit, removing an old circuit, or leaving spare positions open for future work.

On a boat, this is a small part that helps a panel look finished after a breaker has been removed or the layout has changed. It closes open holes in the panel face and keeps unused positions looking consistent instead of patched together.

Before ordering, check that your panel uses a standard toggle circuit breaker opening and that the position you are covering is not needed for an active breaker or related hardware. This plug is meant to blank off an unused opening, not replace a breaker function.

Key features

• Fits a standard toggle circuit breaker hole for blanking off an unused panel opening
• Black finish helps unused breaker positions blend into the panel face
• Pack of 6 covers multiple spare openings or leaves extras on hand for later panel work
• Useful after panel rework, circuit removal, or layout changes during a marine electrical refit

Installation and fit

Installation is straightforward because the plug is made to occupy the same opening used by a standard toggle circuit breaker. It is a practical way to finish a panel after removing a circuit, reworking a distribution panel, or reserving space for a later addition.

This part is a good match for boat owners, installers, and yard teams who want a cleaner panel face at the helm, inside the cabin, or in utility spaces where electrical panels stay in view. Keeping unused openings covered also makes the panel easier to inspect and label during service.
