Induction Stove Electrical: Panel Load, Amps & NEC Code

Switching gas to induction? The electrical math surprises people: a 36 induction cooktop draws 40-50A at 240V -- more than most existing kitchen circuits. NEC Article 220 demand calculations for cooking equipment: a single range counts at nameplate up to 12kW, with demand factors for multiple units. The practical question: does your 100A or 200A panel have headroom, or are you looking at a $2,000-$5,000 panel upgrade that doubles the project cost?

The load calc: existing panel load (HVAC, water heater, dryer -- the big 240V draws) + new induction (nameplate x NEC demand factor) vs panel rating x 0.8 (continuous load rule). Most 200A panels in all-electric homes run 60-80A calculated -- adding 50A induction pushes to the edge but usually fits. 100A panels with electric heat: often no room -- the upgrade becomes mandatory. The workaround: load-management devices (e.g., SimpleSwitch) that pause EV charging or water heating when the stove peaks -- $500-$1,000 vs $3,000 panel upgrade, NEC-compliant under 220.70.

Wire and breaker sizing: 50A induction needs 6 AWG copper (or 4 AWG aluminum) on a 50A breaker -- and the run length matters (voltage drop over 100ft+ may force upsizing). Do not reuse the old gas-stove 120V outlet circuit; induction needs dedicated 240V. Permit and inspect: most jurisdictions require permits for new 240V circuits, and insurance claims after unpermitted electrical work get denied. The calculator runs the NEC demand calc on your panel and tells you: fits, fits with load management, or upgrade required.

The induction cooking experience itself: faster boiling (50% quicker than gas), precise low-heat control (true simmer, unlike gas lowest settings), but cookware constraints (magnetic only -- test with a fridge magnet) and a learning curve on heat settings (power levels, not flame visuals). Most converts never go back; the panel math is the only real friction, and it is solvable.
