Wiring a Kitchen for Electrification

Kitchens are the most circuit-dense rooms in a house, and they're the most expensive place to add circuits after the fact. Which makes the timing advice unusually simple: do it while the kitchen is open.
What does an electric kitchen need?
| Circuit | Purpose |
|---|---|
| 240V range or cooktop | Induction or electric range — the electrification circuit |
| 240V wall oven | If separate from the cooktop |
| Small-appliance circuits (20A) | Countertop receptacles — at least two required |
| Dishwasher | Typically dedicated |
| Garbage disposal | Typically dedicated |
| Refrigerator | Typically dedicated |
| Built-in microwave | Typically dedicated |
| Lighting | Separate from the small-appliance circuits |
The exact requirements — how many small-appliance circuits, which appliances need dedicated circuits, and where GFCI and AFCI protection is required — come from the NEC as adopted in your jurisdiction. Your electrician applies the current rules. See dedicated circuit requirements and GFCI outlet requirements by room.
The electrification circuit
The one that distinguishes an electric kitchen from a gas one: a dedicated 240V circuit for the cooking appliance.
A gas kitchen typically has only a small 120V receptacle behind the range for controls and ignition. Converting means a new circuit from the panel — and that's the real cost of switching to induction.
Size it from the specific appliance's installation instructions, which state the required circuit ampacity. It varies by model and size. See induction cooktop electrical requirements.
Size generously if you can. Conductors in walls are permanent; the appliance is replaceable. A circuit sized for a large cooktop will serve a smaller one fine, and it removes the question if you upgrade later.
Why renovation timing dominates the cost
The circuit itself is inexpensive. The labor of getting it there is not.
During a renovation, with cabinets out and walls open, running a circuit is straightforward — the electrician has clear access, no drywall to cut, no patching, no painting.
Afterward, the same circuit means fishing through finished walls, possibly cutting and patching drywall, and working around installed cabinetry. Often several times the cost, sometimes more depending on the path.
So the advice, even if induction isn't in your immediate plans:
If your kitchen is being renovated, run the 240V range circuit. Terminate it properly. Leave it.
A capped, labeled circuit waiting behind the range turns a future conversion from an electrical project into an appliance delivery. See electrifying on a budget.
Run everything else while you're there
The same logic applies to every kitchen circuit. While walls are open:
- The range circuit, even if you're keeping gas for now
- Additional small-appliance circuits beyond the minimum, if the layout warrants
- A dedicated circuit for any appliance that will want one
- Under-cabinet lighting circuits
- Conduit or a chase to the panel for future additions
The marginal cost of an extra circuit during open-wall work is small. The cost of adding one later is not.
Panel capacity
An all-electric kitchen is a meaningful set of loads, with the 240V cooking circuit the largest.
Before designing:
Run the home electrical load calculator for your full electrification plan — kitchen plus heating, water heating, laundry and EV charging. See how to do a home electrical load calculation.
If you're short:
- A smaller cooktop genuinely reduces the requirement
- 120V induction options — see portable induction and 120V options
- Load management — though cooking is a poor candidate for shedding, so manage other loads instead. See load management for home electrification.
- A subpanel if you need breaker spaces
- A service upgrade if genuinely short
See electrifying without a panel upgrade.
If the panel is being upgraded anyway, this is the moment to run every kitchen circuit — the panel work and permit are largely fixed costs.
Receptacle placement details
Small things that matter on install day:
Range receptacle position. The appliance's installation manual specifies where the receptacle can be so the range sits flush. Getting this wrong means a range that won't push back against the wall.
Cord kits are sold separately. Confirm the configuration matches the receptacle before delivery. See the NEMA plug chart.
Countertop receptacle spacing is governed by code — your electrician applies the spacing rules for your adopted edition.
Island and peninsula receptacles have their own requirements, which have changed across recent code cycles.
Appliance garage and pantry outlets are worth planning while you can.
Ventilation while you're at it
If you're converting from gas, ventilation still matters — cooking produces grease, steam and particulates regardless of the heat source. A ducted hood vented outside remains the right answer.
If the current hood is recirculating, a renovation is the moment to duct it properly. See gas stove indoor air quality and indoor air quality after electrification.
Permits
Kitchen electrical work is permitted work. The inspector checks circuit count and types, GFCI and AFCI protection, receptacle spacing, dedicated circuits, conductor and breaker sizing, grounding, and that the load calculation supports the additions.
See permits for home electrification.
The bottom line
An electric kitchen needs a dedicated 240V cooking circuit on top of the usual small-appliance, dishwasher, disposal and refrigerator circuits. The circuit is cheap; the access is expensive — so run it during a renovation even if you're not converting yet, size it generously, and add every other circuit you might want while the walls are open. Then the future conversion is just an appliance swap.
