What Size Breaker for Electric Range / Oven?
A electric range / oven requires a 50A breaker with 6 AWG wire on a 240V dedicated circuit.
🔌 Wire Length & Voltage Drop Check
Electric Range / Oven Wiring Guide — NEC Requirements
Electric ranges typically require a 40A or 50A/240V dedicated circuit. NEC 220.55 allows demand factors for household cooking equipment. The receptacle must be NEMA 14-50 (4-prong).
Pro Tip
💡 Most modern ranges need a 50A circuit. Check the range nameplate — some smaller units only need 40A.
Why a 50A Breaker?
The electric range / oven draws approximately 40A at 240V (9600W). A 50A breaker provides adequate protection.
Wire Sizing per NEC 310.16
For a 50A/240V circuit, 6 AWG copper is required per NEC Table 310.16 at 75°C. For runs over 75 feet, upsize to 4 AWG (runs over 50ft). Use our Wire Size Calculator and Voltage Drop Calculator.
Complete Parts List
To wire a electric range / oven circuit: a 50A double-pole breaker, 6 AWG NM-B cable (Romex) for interior runs or THHN/THWN-2 in conduit for exposed runs, a NEMA 14-50 receptacle (or hardwired), cable clamps, and appropriate junction boxes.
