Buying Guide
- Amperage and voltage: Choose based on your power needs. Typical RV and boat setups use 30A or 50A at 125V/250V. Higher amperage handles more demanding appliances on larger units.
- Connector type: Ensure compatibility with your existing power pedestal and inlet. Common options include NEMA L5-30P/L5-30R for 30A and NEMA SS2-50P/SS2-50R for 50A.
- Weatherproofing: Look for waterproof boots, locking rings, and sealed housing to protect against rain, salt spray, and dust in marine environments.
- Durability: UV-stable plastics and corrosion-resistant contacts extend life in sun-exposed and salty atmospheres. Nickel-coated copper contacts help resist oxidation.
- Certification: ETL or UL listings indicate compliance with recognized safety standards, which is important for reliability and insurance considerations.
- Length and reach: Cord length matters for reach between shore power pedestals and your setup. Longer cords reduce the need for extensions but add weight and storage considerations.
- Ease of installation: Look for clearly labeled terminations, included hardware, and compatible mounting options for quick and secure setup.
- Maintenance: Consider features like weatherproof lids and robust seals to minimize moisture ingress and corrosion over time.
- Amenities and indicators: LED indicators or status lights help verify power availability, especially in low-light docks or marinas.
- Multi-adapter options: Some kits include dual adapters or multi-port configurations, offering flexibility for branching to different shore power outlets.
