120V Induction Range Circuit
120V Induction Range Breaker & Wire Chart
The wall draw, shared-circuit verdict, and the dedicated breaker, wire, and ground for every 120V plug-in induction range, with a conventional 240V range as the baseline.
Wall Draw, Shared Verdict, Breaker & Wire
| Unit | Wall draw | Share 15A? | Share 20A? | Dedicated (<3h) | Dedicated (cont.) | Ground |
|---|---|---|---|---|---|---|
| Copper Charlie Induction Range | 12 A | Shares at the cap (no headroom) | Can share a circuit | 15A / #14 | 15A / #14 | #14 Cu |
| Impulse Cooktop | 15 A | Needs a 20A or dedicated circuit | Can share a circuit | 15A / #14 | 20A / #12 | #14 Cu |
| Electra Induction Stove | 15 A | Needs a 20A or dedicated circuit | Can share a circuit | 15A / #14 | 20A / #12 | #14 Cu |
| Baseline: conventional 240V range | 40 A / 240V | Dedicated | Dedicated | 40A / #8 | n/a | #10 Cu |
The wall draw is manufacturer-stated; the breaker, wire, ground, and verdict derive from it through the NEC tables. The dedicated (continuous) column applies when the battery recharge runs 3 hours or more (a continuous load, 125% per NEC 210.20(A)). The 240V baseline is the NEC 210.19(A)(3) minimum branch (40A for a range 8-3/4 kW or more), #8 Cu; its neutral may be reduced to 28A (70% of the rating, min #10) per Exception No. 2. The rating plate on the specific unit governs.
Frequently Asked Questions
What breaker and wire does a 120V induction range need?
Size it from the wall / charge draw, never the burner kW. The chart above lists each unit. On a dedicated circuit a 12A unit takes a 15A breaker on #14 copper; a 15A unit takes a 15A breaker on #14 copper. If the recharge runs 3 hours or more it is a continuous load and the circuit is sized at 125%: a 15A unit then needs a 20A breaker on #12 copper (NEC 210.20(A)).
Why does the chart show two dedicated-circuit columns?
Because a 120V plug-in range can be a continuous load, and that flips the sizing. If the battery recharge stays under 3 hours (typical intermittent cooking) the circuit follows the standard branch-circuit rules. If the recharge sustains 3 hours or more it is a continuous load (NEC Art. 100) and the branch circuit and breaker are sized at 125% (NEC 210.20(A) / 210.19(A)(1)). The chart gives both so the answer is honest either way.
Can any of these share a circuit?
Only within the cord-and-plug cap. A freestanding range is not fastened in place, so on a general-purpose / multi-outlet circuit NEC 210.23(B)(1) caps its rating at 80% of the branch: 12A on a 15A circuit, 16A on a 20A. A 12A unit sits at the cap on a 15A circuit; a 15A unit exceeds it and needs a 20A or dedicated circuit. The 240V range anchor is always on its own dedicated circuit.
