A stove plug, also known as a range cord or range plug, connects an electric stove to a dedicated high-voltage outlet. In North America, electric stoves generally require a 240-volt circuit, and the receptacle for these appliances is far larger and uses more robust prongs than standard household outlets. There are two common configurations: 3-prong and 4-prong plugs.
Until the mid-1990s, most homes were built with a 3-prong outlet for ranges, which provided two ‘hot’ wires (each carrying 120 volts) and a combined neutral/ground wire. However, modern electrical code standards require a 4-prong outlet that separates the ground and neutral wires for improved safety[3].
Most new electric stoves are equipped or can be equipped with either a 3-prong or a 4-prong cord, depending on the outlet in your home. If the range’s existing power outlet is a 3-prong configuration, a 3-prong cord can be installed; if it’s a newer 4-prong outlet, a 4-prong cord is required[2]. It is possible to replace the plug on the range to match the installed wall outlet using widely available replacement cords, and manufacturers often provide detailed instructions or diagrams for connecting either configuration[6].
The 4-prong arrangement consists of two hot wires, a neutral wire, and a ground wire, while the 3-prong arrangement omits a separate ground, using the neutral for both[4]. Installation involves accessing the range’s terminal block at the rear, securely attaching the appropriate wires per the manufacturer’s wiring diagram, and clamping the cord in place. This process is considered manageable for most homeowners with basic DIY skills, though caution and strict adherence to safety guidance is essential[2].
It is important to match the amperage and wire gauge of the cord and outlet to the stove’s rating; most modern ranges require either 40-amp or 50-amp outlets, depending on the appliance’s power needs[7]. If switching from an electric to a gas range, the electric stove outlet must be disconnected and replaced with a standard 120-volt outlet, as gas ranges use significantly less electrical power[7].
