The Number That Governs the Circuit

The whole trick of the battery-buffered induction range is that it decouples the burners from the wall. The burners pull 5,000 to 10,000 watts from the integrated battery; the manufacturer caps what comes from the wall to fit a normal 120V branch circuit. So the number that sizes the branch circuit is the wall / charge draw (12 to 15 A at 120V on this roster), never the burner wattage. Sizing a circuit off the 10 kW burner figure would be a serious, and expensive, error; that current never crosses the branch circuit.

The Three 120V Plug-In Units

Each row is the manufacturer-stated wall draw and plug, with the shared-15A verdict and the dedicated circuit derived from it. The wall draw is transcribed from the manufacturer; the breaker, wire, and verdict are computed.

The 120V plug-in induction range roster, with the wall draw, the shared-15A verdict, and the dedicated circuit derived for each
Unit	Plug	Wall draw	Share a 15A?	Dedicated circuit
Copper Charlie Induction Range	NEMA 5-15	12 A	Shares at the cap (no headroom)	15A / #14 Cu
Impulse Cooktop	NEMA 5-15P	15 A	Needs a dedicated circuit	15A / #14 Cu
Electra Induction Stove	Standard 120V outlet	15 A	Needs a 20A or dedicated circuit	15A / #14 Cu

Electra's Breaker Saver feature dials the wall draw between 2 and 12 amps in the app, so a dialed-down unit fits a shared 15A circuit (12A is at the 12A cap).

Can a 120V Induction Range Share a Circuit?

It depends on the mounting. A freestanding range is cord-and-plug connected and not fastened in place, so the governing rule is NEC 210.23(B)(1): on a general-purpose / multi-outlet branch circuit, the rating of one cord-and-plug utilization equipment not fastened in place shall not exceed 80% of the branch-circuit rating. That is 12A on a 15A circuit and 16A on a 20A circuit (the companion Table 210.21(B)(2) states the same 12A / 16A ceiling for a cord-and-plug load on a circuit with two or more receptacles).

A drop-in cooktop is different: it is fixed (fastened or otherwise secured at a specific location, the NEC Art. 100 definition), so the stricter fastened-in-place rule NEC 210.23(B)(2) governs it at 50% of the branch, not the 80% (B)(1) rule: 7.5A on a 15A circuit and 10A on a 20A circuit. The cord-and-plug connection does not change that; “fastened in place” is about the physical mounting, not the plug. A range you can pull out is not fastened in place; a cooktop dropped into the counter is, so a 15A cooktop cannot share even a 20A general-purpose circuit and needs a dedicated one.

The at-cap case: 12 A is exactly the 12 A cap for a general-purpose / multi-outlet 15 A circuit (15 A x 80% = 12 A), so it is permitted but leaves zero headroom for any other load on that circuit; a 20 A circuit or a dedicated circuit gives margin.

The gotcha the marketing skips: 15 A exceeds the 7.5 A cap for a general-purpose / multi-outlet 15 A circuit (15 A x 50% = 7.5 A), so it is NOT permitted to share a 15 A circuit; it needs a dedicated individual branch circuit. This is more conservative than the “no panel upgrade” pitch, and it is the correct read: a 15A wall draw fills a 15A circuit, so it cannot also carry a toaster or a microwave.

On a true individual branch circuit (one receptacle, nothing else) the 80% multi-outlet cap does not apply; the individual-branch and continuous-load rules govern instead.

Is It a Continuous Load?

It depends on how long the battery recharges. A load that runs 3 hours or more is a continuous load (NEC Art. 100), and the branch circuit and breaker are then sized at 125% (NEC 210.20(A) / 210.19(A)(1)). If cooking cycles keep the recharge under 3 hours, the circuit follows the standard branch-circuit rules with no adder: a 12A unit on a 15A / #14 Cu dedicated circuit, a 15A unit on 15A / #14 Cu. If the recharge sustains 3 hours or more it flips to continuous: a 12A unit at 125% is 15A, which still fits a 15A / #14 Cu circuit; a 15A unit at 125% is 18.75A, which needs a 20A / #12 Cu circuit.

What It Adds to the Service Load

A 120V plug-in battery-buffered range adds only about 1.44 to 1.8 kVA to the service calculation, not the 8 kW Table 220.55 Column-C figure a conventional 240V range gets. A 12A unit (1.44 kVA) is under the 1-3/4 kW Table 220.55 threshold, so it is counted as an ordinary appliance load. A 15A unit (1.8 kVA) is just over it, so Table 220.55 Note 3 applies the Column A single-unit 80% demand factor: 1.8 x 0.80 = 1.44 kW. Both land near 1.44 kW, far below the 8 kW a 240V range demands, which is exactly why one fits a service that could not take another 240V range.

Where these induction-range circuit numbers come from

The shared-circuit verdict, the dedicated wire and breaker, and the service-load contrast on this page are computed by the locked engine from the NEC 2023 rules below. These figures live in one locked module rather than being retyped page by page, so every place this number appears is the same number. Every release runs this site's own checks against that locked module before it ships, and the source is cited above so you can hold the number to the document yourself. Everything is sized from the WALL / charge draw off the rating plate, never the battery-fed burner wattage, through the same locked wire-size tables the rest of the site uses.

NEC 210.23(B)(1) and 210.23(B)(2): The shared general-purpose / multi-outlet circuit cap. A freestanding cord-and-plug range is not fastened in place, so its rating may not exceed 80% of the branch (210.23(B)(1)): 12 A on a 15 A circuit, 16 A on a 20 A. A drop-in cooktop is a fixed (fastened-in-place) appliance, so the tighter 50% cap governs it (210.23(B)(2)): 7.5 A on 15 A, 10 A on 20 A. The 80% rule would over-permit a fixed cooktop, so the engine keys the cap off the unit's mounting. Fetched from the primary (p.70-85).
NEC 210.21(B)(2) and Table 210.21(B)(2): The companion receptacle limit: a cord-and-plug load on a circuit with two or more receptacles is held to the same 12 A (15 A circuit) / 16 A (20 A circuit) ceiling.
NEC 210.20(A) and Article 100 (continuous load): A load that runs three hours or more is continuous, so the branch and its overcurrent device are sized at 125%. A multi-hour battery recharge is the one thing that flips a plug-in range continuous, so the dedicated-circuit answer is given both ways (continuous and not) rather than asserting one.
NEC 210.19(C): The conventional 240 V range this plug-in unit displaces: a household range rated 8-3/4 kW or more requires a minimum 40 A branch circuit, with the neutral permitted smaller than the ungrounded conductors by Exception No. 2 (not less than 70% of the branch rating and not smaller than #10). Verified against the NFPA 70-2023 primary (p.70-84); the 2020 NEC relocated this household-range rule to its current 210.19(C) location, which the engine cites.
NEC Table 220.55: The service and feeder cooking-appliance demand. A 120 V plug-in unit adds only about 1.4 to 1.8 kVA: under 1-3/4 kW it is an ordinary appliance load not in the table, and just over it, Table 220.55 Note 3 applies the Column A single-unit 80% demand factor. Either way it is NOT the 8 kW Column C figure a conventional 240 V range receives.
NEC Table 310.16, 240.4(D), and Table 250.122: The dedicated individual branch circuit is sized through the locked wire-size engine: conductor ampacity from Table 310.16 with the 110.14(C) terminal cap, the small-conductor overcurrent cap on #14/#12/#10 (240.4(D)), and the equipment grounding conductor from Table 250.122. Fetched from the primary.

These are NEC 2023 rules and referenced tables, looked up and applied by the engine to the wall/charge draw you enter, not field measurements. The burner peaks are battery-fed and never size the branch. The unit rating plate has the final say on the wall/charge draw, and your AHJ and local amendments govern the install.

Frequently Asked Questions

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. 23332 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.

Can a 120V plug-in induction range share a circuit?

It depends on the wall draw AND the mounting. A freestanding cord-and-plug range is not fastened in place, so NEC 210.23(B)(1) caps its rating at 80% of a general-purpose / multi-outlet circuit: 12A on a 15A circuit, 16A on a 20A circuit (companion Table 210.21(B)(2)). A 12A range like the Copper Charlie Induction Range sits exactly at the 12A cap on a shared 15A circuit (permitted, zero headroom; a 20A circuit gives margin); a 15A freestanding range like the Electra Induction Stove exceeds the 12A cap and needs a 20A or dedicated circuit. A drop-in COOKTOP like the Impulse Cooktop is fixed (fastened in place), so the stricter NEC 210.23(B)(2) 50% cap governs it (7.5A on 15A, 10A on 20A): its 15A draw exceeds both, so it needs a dedicated circuit, not a shared 20A. On its own individual branch circuit these shared caps do not apply.

What breaker and wire does a 120V induction range need?

Size it from the WALL / CHARGE draw off the rating plate, never the induction burner kW (the burners pull 5-10 kW from the battery, not the wall). 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 battery recharge runs 3 hours or more it is a continuous load and the circuit is sized to 125% (NEC 210.20(A)): a 15A unit then needs a 20A breaker on #12 copper.

Do these ranges really not need a panel upgrade?

That is the whole point of the battery-buffered class: it runs on an ordinary 120V branch circuit instead of a dedicated 240V range circuit. But "no panel upgrade" is not the same as "share any outlet." A 15A unit fills a 15A branch, so it wants a circuit to itself. A freestanding range at 15A can step up to a 20A circuit (the 80% cap is 16A there); a drop-in cooktop is fastened in place, so the 50% cap of NEC 210.23(B)(2) (10A on a 20A circuit) governs it and it needs a dedicated circuit either way. The conservative, code-correct read is more restrictive than the marketing.

How much does a 120V induction range add to my service load?

Only about 1.44 to 1.8 kVA, not the 8 kW Table 220.55 Column-C figure a conventional 240V range gets. A 12A unit (1.44 kVA) is under the 1-3/4 kW Table 220.55 threshold, so it is counted as an ordinary appliance load. A 15A unit (1.8 kVA) is just over it, so Table 220.55 Note 3 applies the Column A single-unit 80% demand factor: 1.8 x 0.80 = 1.44 kW. Either way it is far below the 8 kW Column-C demand of a 240V range, which is why it fits a service that could not take another 240V range.

120V plug-in vs a conventional 240V induction range: what is the wiring difference?

A 120V plug-in unit runs on a 15A / 120V branch circuit from a standard outlet (a 12A unit on #14 copper), no panel work. A conventional 240V range takes a dedicated 40A / 240V circuit on #8 copper with a #10 ground, per NEC 210.19(C) (a range 8-3/4 kW or more requires a minimum 40A branch), usually on a NEMA 14-50 4-wire receptacle. The plug-in class exists precisely for kitchens with no 240V circuit and no spare panel capacity.
