What kind of cord do you need for your generator?

Special generator power cords are widely available and designed for use with generators found in residential and commercial settings. Essentially, these cords function as heavy-duty extension cables that connect directly to your home’s power supply via an inlet box or to specific appliances like water heaters.

When choosing a generator cord, the important factor is selecting a cable that matches the correct amperage. For instance, you should use a 50-amp generator cord for a 50-amp outlet, and similarly, a 30-amp cord for a 30-amp outlet.30-amp generators support up to 3,600 watts, typically used for RVs, camping, or small home backup applications. In contrast, 50-amp generators can handle up to 12,000 watts, making them ideal for larger RVs, commercial use, or extensive home backup systems.

A general rule is to choose a generator cord that corresponds to the amperage outlet available on your generator, as many models may feature a combination of outlet types. Always refer to the manufacturer’s guidelines when making your selection. Other less common options include 25-amp and 40-amp cords, which are designed for specific generators, but these are less frequently needed.

In addition to amperage, you’ll need to select the correct prong type for your outlet. 30-amp generator plugs come in two variations: a 3-prong type for 120 volts, and a 4-prong type capable of handling both 120 and 240 volts. The 4-prong plugs are becoming increasingly common as more homes use 240-volt appliances and outlets.

For a 50-amp generator outlet, a specialized power cord is generally required. These cords typically feature a straight-blade male plug on one end for connection to the generator, and a twist-lock female connector on the other end, which links to a transfer switch or power inlet box.
