AC circuit breaker lockout slide that allows only one double-pole source breaker to be active at a time, helping prevent shore power and generator or inverter power from being connected simultaneously.

The Blue Sea Systems 4125 mounts alongside compatible double-pole circuit breakers in marine and RV AC electrical panels. It fits World, A-Series, and Rocker double-pole circuit breakers and uses existing breaker mounting screw holes, so no special panel modification is required. Included mounting screws support a straightforward installation.

Restricts activation to one double-pole AC circuit breaker at a time, preventing simultaneous source selection.
Helps keep shore power separate from generator or inverter power, reducing the risk of mixing AC sources.
Fits World, A-Series, and Rocker double-pole circuit breakers for compatible panel configurations.
Uses existing circuit breaker mounting screw holes, avoiding special panel modifications.
Includes mounting screws for installation.

Use the 4125 in a marine or RV AC distribution panel where two power sources share source-selection breakers. The slide physically limits operation so only one compatible double-pole breaker can be activated at a time, helping keep shore power and generator or inverter power separate. Its mounting approach uses the circuit breaker screw holes rather than requiring a custom panel cutout or other special modification. Install it with compatible World, A-Series, or Rocker double-pole breakers and confirm the panel arrangement before fitting. The included mounting screws provide the hardware specified for installation.
