Electric Range Wire Sizing: Nec Requirements And Safety Standards

Electric range wire size is determined by the National Electrical Code (NEC), which sets safety standards for electrical wiring and equipment. The code specifies the minimum wire size for electric ranges based on the amperage draw of the appliance. For example, a range with an amperage draw of 30 amps requires a minimum wire size of 8 AWG (American Wire Gauge). The NEC also requires that the wire be copper or aluminum with a type THHN or XHHW insulation rating.
