LOEMU 50 Amp Generator Cord, 50Ft
LOEMU offers a longer 50-foot option designed for larger properties or installations where the inlet box is farther from the generator. It features 6/3 + 8/1 gauge conductors, a 14-50P male plug, and a SS2-50R female receptacle with a locking ring. The cable jacket and insulation are built to endure outdoor exposure, resisting moisture, sunlight, and abrasion. This length helps reduce voltage drop in longer runs and provides flexibility for generator placement away from structures.
Key features to note:
– 50 ft length for greater reach
– Heavy-duty STW cable with 6/3 + 8/1 gauge
– Locking twist-lock connectors and outdoor-ready construction
Buying Guide: Key Purchase Considerations
- Length vs. setup needs: Short cords reduce clutter but may require closer positioning of the generator; longer cords offer flexibility but can add resistance and tangling if not managed properly.
- Connectors and compatibility: Ensure the cord uses NEMA 14-50P and SS2-50R (or CS6375) configurations, with a locking ring for a secure connection to power inlets or transfer switches.
- Construction and weatherproofing: Look for heavy-duty STW jackets, UL/ETL certification, and twist-lock designs to resist wind, rain, and temperature extremes.
- Electrical rating: Verify 250V and 50A compatibility, with a power rating around 12,500W for typical home backup or RV use. Pure copper conductors often provide better conductivity and durability.
- Applications: Choose based on intended use—RV camping, home backup, or professional outdoor sites. Shorter cords are ideal for tight spaces; longer cords suit distant inlets or multiple inlet boxes.
- Durability and safety certifications: ETL or similar listings support compliance with safety standards. A locking mechanism reduces the risk of accidental disconnection during critical power events.
Comparative Considerations
- Cost vs. length: Longer cords typically cost more; balance the need for distance against budget and storage space.
- Ease of use: Twist-lock connectors offer straightforward engagement and secure locking, which is important during inclement weather.
- Material quality: Copper conductors and robust insulation help maintain stable voltage and reduce heat buildup under load.
- Environmental suitability: For frequent outdoor use, look for weather-resistant jackets and connectors designed to withstand UV exposure and temperature swings.
