120V Induction Range Circuit
Copper Charlie Induction Range: Circuit & the Shared-Circuit Verdict
The circuit the Copper Charlie Induction Range needs, sized from the 12A wall draw the manufacturer states (never the induction burner kW), with the NEC shared-circuit verdict.
Circuit Spec
| Plug / voltage | NEMA 5-15 (120V) |
| Wall / charge draw (manufacturer-stated) | 12 A |
| Share a general-purpose 15A circuit? | Shares at the cap (no headroom) |
| 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) | 15A / #14 Cu (15A design) |
| Equipment ground | #14 Cu |
| Service-load contribution | ~1.44 kVA (vs 8 kW for a 240V range) |
| Battery | ~5.37 kWh |
| Safety listing | Not printed by the manufacturer |
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.
Models
Representative models in this line: CURB30SS, CURB30WT, CURB30BL. The circuit spec above applies across the line as published by Copper; confirm against the rating plate on the specific unit.
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: 12 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.

Circuit data transcribed from the manufacturer: Copper Charlie Induction Range specification, accessed 2026-07-11. Sourced from the manufacturer's product page rather than a spec sheet PDF.
The Copper Charlie (Channing St. Copper Co.) is a 30-inch freestanding induction range that plugs into a standard NEMA 5-15 outlet and draws 12A from the wall (the product page states 120V, 60 Hz, 12A). Its ~5 kWh LFP battery supplies the burner peaks, so the wall draw stays at 12A no matter how hard the burners run. The spec PDF adds 'dedicated circuit recommended for optimum performance.'
Frequently Asked Questions
Can the Copper Charlie Induction Range share a circuit?
On a general-purpose / multi-outlet circuit, 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. On a 20A circuit: 12 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 Copper Charlie Induction Range need?
Size it from the 12A 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)): 12 x 1.25 = 15A, a 15A breaker on #14 copper.
Does the Copper Charlie Induction Range need a dedicated circuit?
Not strictly, but it is close. Copper's spec sheet recommends a dedicated circuit for optimum performance, but the product page states it can also share an outlet with another appliance (the battery pauses charging to stay in-branch). Dedicated is RECOMMENDED, not required.
How much does the Copper Charlie Induction Range add to my service load?
About 1.44 kVA (12A x 120V), under the 1-3/4 kW Table 220.55 threshold, so it is counted as an ordinary appliance load (1.44 kVA). 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.
