120V Induction Range Circuit
Impulse Cooktop: Circuit & the Shared-Circuit Verdict
The circuit the Impulse Cooktop needs, sized from the 15A wall draw the manufacturer states (never the induction burner kW), with the NEC shared-circuit verdict.
Circuit Spec
| Plug / voltage | NEMA 5-15P (120V or 240V) |
| Wall / charge draw (manufacturer-stated) | 15 A |
| Share a general-purpose 15A circuit? | Needs a 20A or dedicated circuit |
| Share a general-purpose 20A circuit? | Can share a circuit |
| Dedicated circuit (recharge under 3 h) | 15A / #14 Cu |
| Dedicated circuit (continuous, 3 h+ recharge) | 20A / #12 Cu (18.75A design) |
| Equipment ground | #14 Cu |
| Service-load contribution | ~1.44 kVA (vs 8 kW for a 240V range) |
| Battery | ~3 kWh |
| Safety listing | UL 858 |
The wall draw is the manufacturer-stated value; the breaker, wire, ground, verdict, and service-load figure derive from it. The rating plate on your unit governs.

Can It Share a Circuit?
A freestanding range is cord-and-plug connected and 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 (companion Table 210.21(B)(2)). On a 20A circuit: 15 A is within the 16 A cap for a general-purpose / multi-outlet 20 A circuit (20 A x 80% = 16 A), so it may share that circuit.

The Impulse Cooktop (Impulse Labs) is a four-burner 30/36-inch cooktop with a 3 kWh LFP battery, certified to UL 858. It runs on 120V/15A (NEMA 5-15P) OR a 240V circuit; the burners deliver up to 10,000 watts of peak power per burner from the battery, but the wall side is a 15A branch. Impulse's own pages do not print a continuous wall-draw figure below the 15A breaker rating, so none is invented here.
Frequently Asked Questions
Can the Impulse Cooktop share a circuit?
On a general-purpose / multi-outlet circuit, 15 A exceeds the 12 A cap for a general-purpose / multi-outlet 15 A circuit (15 A x 80% = 12 A), so it is NOT permitted to share a 15 A circuit; it needs a 20 A circuit or a dedicated individual branch circuit. On a 20A circuit: 15 A is within the 16 A cap for a general-purpose / multi-outlet 20 A circuit (20 A x 80% = 16 A), so it may share that circuit. The rule: NEC 210.23(B)(1) (cord-and-plug equipment not fastened in place, 80% of a general-purpose / multi-outlet branch circuit) with the companion receptacle limit of NEC 210.21(B)(2) and Table 210.21(B)(2).
What breaker and wire does the Impulse Cooktop need?
Size it from the 15A wall / charge draw off the rating plate, never the induction burner kW (those peaks come from the battery). On a dedicated individual branch circuit it takes a 15A breaker on #14 copper with a #14 copper equipment ground. 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)): 15 x 1.25 = 18.75A, a 20A breaker on #12 copper.
Does the Impulse Cooktop need a dedicated circuit?
At its full 15A wall draw it exceeds the 12A cord-and-plug cap for a shared 15A circuit, so it needs a 20A circuit (16A cap) or a dedicated individual branch circuit. Impulse states a 15A breaker minimum for both the 120V and 240V use cases and that the panel does not need to be upgraded. It does not state 'dedicated'; it plugs directly into an existing 120V outlet, but a 15A wall draw fills a 15A circuit, so it wants that circuit to itself (or a 20A circuit) rather than sharing a 15A one.
How much does the Impulse Cooktop add to my service load?
About 1.8 kVA (15A x 120V), just over the 1-3/4 kW Table 220.55 threshold, so Note 3 applies the Column A single-unit 80% demand factor: 1.8 x 0.80 = 1.44 kW. That is far below the 8 kW Column-C demand a conventional 240V range gets, which is why it fits a service that could not take another 240V range.
