30 amp twist-lock power inlet for trailers, RVs, and marine use. Provides a secure, weather-resistant shore power connection for reliable 125V AC input.
Twist-lock inlets must match your shore power cord configuration. This inlet is designed for standard 30 amp RV-style systems and will not mate with mismatched plug types.
Use correct wire gauge (10 AWG minimum) and ensure all terminal connections are secure to prevent overheating and voltage drop.
