Electra Induction Stove: Circuit & the Shared-Circuit Verdict

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). Electra's Breaker Saver can dial the wall draw down to 12A, which sits exactly at the 12A cap, so a dialed-down unit fits a shared 15A circuit.

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.

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. Electra plugs into a standard 120V outlet (no renovation required) and states 120V, 15A. It imposes no dedicated-circuit requirement and adds explicit shared-circuit support: the Breaker Saver feature dials the wall draw between 2 and 12 amps to avoid tripping the breaker, the strongest adjustable wall-draw bound on this roster.

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.
