The SUPCO src4-40-6 is a heavy-duty electric range power cord rated for 250 volts and 40 amps, designed to connect a freestanding electric range to a standard 4-wire household outlet. At 6 feet in length, the cord provides enough reach for most standard kitchen installations where the outlet is located behind or beside the appliance. The 4-wire configuration includes a separate ground conductor, which is required by the National Electrical Code for new construction and most modern installations. Licensed electricians and appliance installation technicians are the primary trades handling this type of connection.
This cord is suited for residential kitchen installations where a freestanding electric range or oven requires a direct connection to a 240-volt, 40-amp circuit. The 6-foot length accommodates typical cabinet and appliance layouts without excess slack. The 4-wire design meets current NEC requirements for residential range circuits, making it appropriate for new installations and code-compliant replacements of older 3-wire setups.
Designed as an OEM-style replacement range power cord for freestanding electric ranges requiring a 4-wire, 40-amp, 250-volt connection.
Installation should be performed by a licensed electrician or qualified appliance installer in accordance with local electrical codes and NEC Article 422. Disconnect and lock out power at the circuit breaker before making any connections at the range terminal block. Confirm the outlet and circuit are rated for 40 amps at 240 volts before connecting this cord. Do not use this cord on circuits or outlets rated below the cord specifications.
