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.

Quick answer: a 12A unit takes a 15A / #14 Cu dedicated circuit and sits at the 12A shared-15A cap; a 15A unit takes a 15A / #14 Cu circuit (or 20A / #12 Cu if the recharge is continuous) and, as a fixed-in-place drop-in cooktop (NEC 210.23(B)(2) 50% cap), needs a dedicated circuit. The baseline 240V range: 40A / #8 Cu. The chart has every unit.

Wall Draw, Shared Verdict, Breaker & Wire

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(C) 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.

Intry Verified. The dedicated breaker, copper conductor, ground, and the shared-circuit verdict in this chart are computed from each unit's manufacturer wall draw through NEC 210.23(B), 210.19(A), 210.20(A), and Table 310.16 by the same locked wire-size engine on every build. Those figures are computed by a locked engine straight from the source it cites, not hand-typed, and that computation re-runs inside a deterministic test on every deploy. Source-checked. Locked. This is our own deterministic gate, not a third-party audit. What Intry Verified means

Run this in your AI. Ask Claude or ChatGPT to size the breaker and wire for a 120V induction range from its wall draw and it runs the Intry 120V Induction Range Circuit Calculator tool live, handing back the verdict with its cited source instead of a guess. Then keep the reading as one job in the Intry app.

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?

It depends on the mounting. 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 range sits at the cap on a 15A circuit; a 15A freestanding range exceeds it and needs a 20A or dedicated circuit. A drop-in cooktop like the Impulse Cooktop is fixed in place, so the stricter NEC 210.23(B)(2) 50% cap governs (7.5A/15A, 10A/20A) and it needs a dedicated circuit. The 240V range anchor is always on its own dedicated circuit.

Is the Intry 120V Induction Range Circuit Calculator accurate and NEC compliant?

Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 23724 automated checks re-derive and source-check the numbers against the cited NEC section before each deploy. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
