Buying Guide
What to consider when choosing a generator-to-house cord:
- Current and voltage rating: Match the cord to your generator’s output and the transfer switch or panel rating. Common setups are 30A at 125/250V or 50A at 125/250V.
- Conductor size and build: 10 AWG or larger is preferable for longer runs and higher wattages; look for STW or SJTW jackets for outdoor use.
- Locking mechanism: Twist-lock L14-30 or SS2-50 connectors provide a secure link against wind and movement.
- Length: Shorter cords reduce voltage drop; choose length that balances reach with minimal loss.
- Weatherproofing: For outdoor use, ensure IP ratings or weatherproof design and ETL listing.
- Inlet box features: Pre-drilled or easily accessible inlet boxes simplify installation and reduce on-site drilling.
- Compatibility: Verify that the cord’s plug and receptacle types align with your generator and transfer switch.
