What Size Breaker Do You Need for an Electric Stove? NEC 220.55 Guide 2026
Most standard electric ranges and stoves require a 50 amp, 240V double-pole breaker with 6 AWG copper wire and a NEMA 14-50R receptacle. This has been the standard for decades and covers ranges rated up to 12 kW. However, smaller cooktops may only need a 30-40A circuit, while professional ranges can require 60A.
The Standard: 50A Breaker with 6 AWG Wire
Per NEC 220.55 and Table 310.16, a standard household electric range (8-12 kW) requires a 50 amp, 240V circuit. This is the most common setup and has been the industry standard for decades. The circuit uses 6 AWG copper NM-B cable (6/3 with ground), a double-pole 50A breaker, and terminates at a NEMA 14-50R receptacle.
Breaker Size by Range Wattage
Not all ranges need 50A. Small cooktops drawing 3-4 kW may only need a 30A circuit with 10 AWG wire. Standard freestanding ranges (8-12 kW) use a 50A circuit. Professional ranges with multiple ovens and high-BTU burners (12-16 kW) may need a 60A circuit with 4 AWG wire. Always check the nameplate on your specific appliance — the manufacturer's rating determines the minimum circuit size.
NEC 220.55 — Demand Factors for Cooking Equipment
NEC 220.55 and Table 220.55 allow demand factors for household cooking equipment. For a single range rated 12 kW or less, the demand load is 8 kW. This means your 12 kW range only counts as 8 kW for panel load calculations — a significant reduction. This demand factor is why a 50A circuit works even for ranges with nameplate ratings above 10 kW. For multiple cooking appliances, additional demand factors apply per Column A, B, or C of Table 220.55.
Outlet Types: 3-Prong vs 4-Prong
NEC 250.140 requires all new range installations to use a 4-wire connection (two hots + neutral + ground) with a NEMA 14-50R receptacle. The older 3-prong NEMA 10-50R outlets (two hots + neutral, no separate ground) are only permitted on existing installations that have not been modified. If you are replacing an outlet or running a new circuit, it must be 4-wire. The separate equipment ground provides critical safety protection that the old 3-wire connections lack.
| Range Type | Typical kW | Breaker | Wire (Cu) | Outlet |
|---|---|---|---|---|
| Small Cooktop | 3-4 kW | 30A | 10 AWG | NEMA 14-30R |
| Standard Cooktop | 5-7 kW | 40A | 8 AWG | NEMA 14-50R |
| Standard Range | 8-12 kW | 50A | 6 AWG | NEMA 14-50R |
| Large Range | 12-14 kW | 50A | 6 AWG | NEMA 14-50R |
| Pro Range | 14-16 kW | 60A | 4 AWG | NEMA 14-60R |
Can an Electric Stove and Oven Share a Circuit?
If both are separate permanently-connected appliances, NEC 220.55 Note 4 allows combining them on one circuit if the total doesn't exceed the circuit rating. However, if your range has a built-in oven and cooktop (most freestanding ranges), it's already one appliance on one circuit. A separate wall oven and cooktop may share a circuit using demand factors, but each must be individually protected. Consult an electrician for complex multi-appliance installations.
