Full-size electric ranges typically need a 40-50 amp, 240-volt dedicated circuit. Most modern ranges require a 50A circuit.
| Recommended wire | 6/3 NM-B or 6 AWG THHN |
| Breaker | 50A double-pole |
| Voltage | 240V |
| Typical amperage | 40A |
| Circuit amperage | 50A |
| NEC reference | NEC 220.55 |
| Max recommended distance | 35 feet (without voltage drop concerns) |
Smaller cooktops may only need a 40A circuit with 8 AWG wire. Always check the nameplate rating.
