What to Look for in a 30 Amp Generator Cord
When investing in a generator extension cord, here are some key features to consider:
Length
Length determines the flexibility of your generator setup. If you need to place the generator at a safe distance, opt for 40 to 50 feet. For closer or indoor applications, 15 to 25 feet is sufficient.
Gauge
All featured cords use 10-gauge wire, which is appropriate for 30 Amp currents over longer distances. Thicker gauges (lower numbers) reduce resistance and heat buildup.
Weatherproof Rating
Look for IP65 waterproof or all-weather resistant ratings if you plan to use your cord outdoors. These ratings protect against rain, snow, and dust intrusion.
Connector Type
Ensure you’re using a 4-prong plug (NEMA L14-30P to L14-30R), which safely provides two 120V hot wires, a neutral, and a ground wire. This setup is required for 240V applications and transfer switch compatibility.
Build Quality
Heavy-duty PVC or rubber jackets, molded plug ends, and secure locking mechanisms enhance safety and longevity.
