Blue Sea 8567 AC Toggle Source Selector (230V) - 2 Sources + 4 Positions

The Blue Sea 8567 AC Toggle Source Selector (230V) is a dual-source marine and industrial electrical control panel designed to safely manage power distribution between two independent AC sources. This switchgear solution prevents backfeeding and simultaneous connection of both sources—a critical safety requirement in marine systems, RV installations, and backup power applications where AC generator switching must be fail-safe and reliable.

The unit incorporates dual-pole main circuit breakers with integrated lockout mechanisms rated for a maximum panel amperage of 50 amperes. Two 16-amp double-pole breakers and two 8-amp single-pole breakers provide individual branch circuit protection while the red reverse-polarity LED indicator alerts operators to wiring faults before damage occurs. All hot, neutral, and safety ground connections are fully rated and engineered to European 230V AC standards, delivering consistent protection across the four selectable switching positions.

This selector is built for applications requiring reliable AC source switching without the risk of dual-source connection—standard in maritime electrical systems, shore power selection on vessels, emergency generator integration, and industrial facility backup power. The white switch mechanism and compact form factor allow straightforward panel mounting in engine rooms, electrical cabinets, and utility compartments where space and clarity are priorities.

Operators familiar with marine electrical standards or industrial backup power systems recognize the importance of positive isolation between AC sources. The 8567's design eliminates the possibility of paralleling incompatible sources, protecting equipment downstream and preventing nuisance breaker trips or voltage conflicts that damage sensitive electronics.
