Not all of these plugs are available on the generators we sell, please note that this is simply a diagram of plugs for you to reference during your research.

Amps	Watts	Notes
	5,000 and Less	Most residential generators have 20-amp outlets. If it has a 30-amp outlet too, get the 30-amp system so it can accommodate all of the wattage.
	5,000 - 7,500	Some generators have 3-prong outlets. If you don't need a 240 volt breaker, you can save by getting a 3-prong system.
	5,000 - 7,500	If you need a 240 volt breaker, you'll need a 4-prong system. If you're not sure, always go with the 4-prong system.
	7,500 - 12,500	Most 50-amp systems feature twistlock plugs, but most larger generators use straight-blade outlets. If your generator has a straight-blade outlet, simply cut off the male twistlock plug and replace it with a straight-blade plug.
