Generator Power Cords

Generator Cords

Generator Cords connect a portable generator to a home in one of two ways. The preferred method connects the generator 120/240-Volt Receptacle to a matching plug on a Transfer Switch Inlet Box. The generator supplies all the circuits in the transfer switch without additional extension cords.

Some Generator Power Cords plug into one or two 120-Volt Outlets or a single 120/240-Volt Outlet on the generator. The opposite end of the Generator Cord has multiple 120-Volt Outlets. This arrangement brings power from the generator into the house with a single cord rated for outdoor use and the power it will carry.

Generator Cord

Choose a generator cord that fits your purpose and your generator. A Generator that supplies both 120 and 240 Volts will offer one or more 120/240-Volt Receptacles. A 30-Amp Receptacle requires a cord with an L14-30P plug on it. 50-Amp Receptacles require a Generator Cord with a 50-Amp plug. Never use a 30-Amp Cord with a 50-Amp Generator Receptacle.

Generator Power Cords that split the load from a 120/240-Volt outlet have two or four outlets on the house side. Try to load the outlets evenly. A four-receptacle or two-receptacle cord splits the load between the left and right receptacles. Connect loads to each side instead plugging everything into one side or the other.

Generator Power Cords

Whether they connect to an inlet box or carry power inside to plug your appliances into, Generator Power Cords all have one thing in common. Each has a plug end and a receptacle end. This prevents shock and electrocution hazards. If the plug accidentally disconnects from the appliance or inlet box, there are no exposed conductors to shock or electrocute someone.

A Generator Power Cord should always follow the rule: Plug on the generator end, receptacle on the house end of the cord. Never build a homemade cord that does not follow this rule.

Generator Power Cord

Select a Generator Power Cord rated for the power it will carry. A 30-Amp generator outlet with a 30-Amp breaker will never supply over 30 amps. Buy a 30-Amp Cord. The same is true for a 50-Amp outlet and breaker. Follow this rule if you purchase an extension cord for use with your generator.

Purchase a Generator Power Cord long enough to keep the generator a minimum of 10 feet from the house. 20-feet away is better. Place the generator where the prevailing wind will not blow exhaust against your home or a neighbor’s home. Remember, if you’re running the cord indoors to plug in appliances, you need a minimum 20-foot cord.
