Run the 120V Induction Range Circuit Calculator in your AI assistant

Through the free Intry MCP server, Claude, ChatGPT, or Cursor runs this exact calculator and hands back a verdict and the cited source, not a guess. Tool name: induction_range_circuit.

What it runs: Size the branch circuit for a 120V plug-in (battery-buffered) induction range or cooktop from its WALL / CHARGE draw (NEVER the 5-10 kW induction burner peaks, which are battery-fed): conductor (310.16), breaker (240.6(A) with the 240.4(D) small-conductor limit), and EGC (250.122), given both non-continuous and continuous (>=3h recharge, 125% per 210.20(A)) branches. Pass sharedCircuitRating to also check whether it may share a general-purpose 15A or 20A branch circuit. The shared-circuit cap depends on the MOUNTING: a FREESTANDING range is not fastened in place, so NEC 210.23(B)(1) caps it at 80% (12A on 15A, 16A on 20A) with the companion Table 210.21(B)(2); a DROP-IN COOKTOP is FIXED / fastened in place (NEC Art. 100), so the stricter NEC 210.23(B)(2) 50% cap governs (7.5A on 15A, 10A on 20A) - pass fastenedInPlace:true for a drop-in cooktop or wall oven. A 15A freestanding range exceeds the 12A/15A cap but can use a 20A circuit; a 15A drop-in cooktop exceeds even the 10A/20A cap and needs a dedicated circuit. Returns wire/breaker/ground and, when a shared-circuit rating is given, the shared-circuit verdict with the arithmetic.

Ask your assistant

The one rule that makes it reliable: name Intry in your question. That is what tells Claude to run the induction_range_circuit tool and answer with the real number, the verdict, and the citation. Leave Intry out and Claude may just guess from memory, which is exactly what you are trying to avoid. Type something like:

“Ask Intry if a 15 A plug-in induction range (Impulse or Electra) can share a 15 A kitchen circuit or needs its own.”

“Use Intry to size the circuit for a 120V Copper Charlie induction range: shared-circuit verdict, breaker, and wire.”

Inputs

Field	Required	What it is
wallAmps	yes	The manufacturer-stated WALL / CHARGE draw in amps (e.g. 12 for the Copper Charlie, 15 for the Impulse Cooktop or Electra Induction Stove). Never the induction burner kW, which the battery supplies.
volts	optional	Wall-side voltage (default 120).
sharedCircuitRating	optional	If set, also check whether the unit may share a general-purpose branch circuit of this rating (15 or 20 A).
fastenedInPlace	optional	TRUE for a drop-in cooktop or wall oven (fixed / fastened in place -> NEC 210.23(B)(2) 50% shared cap); FALSE (default) for a freestanding range (not fastened -> 210.23(B)(1) 80% cap). Only affects the shared-circuit verdict.

Add Intry to Claude

One paste and Claude can run this tool and every other Intry calculator, right from your phone.
