• Prevents mixing of AC power from 2 or 3 sources (shore power, genset, and inverter)
• Compatible with all Blue Sea World Series, A-Series, and Rocker double pole circuit breakers
• Simple installation using existing circuit breaker mounting screw holes
• No panel modification required for installation
• Includes all necessary mounting hardware
• Three position configuration for managing multiple power sources
• Two pole design for standard AC applications

This lockout slide is an essential component for boats with multiple AC power sources, providing foolproof source selection and eliminating the risk of connecting incompatible power sources. The mechanical interlock design ensures reliable operation and peace of mind when switching between shore power, generator, and inverter systems.
