NEC Requirement
NEC 210.52(B) requires at least two 20-amp small-appliance branch circuits serving kitchen countertop outlets. Major appliances (range, dishwasher, microwave, refrigerator, garbage disposal) each need their own dedicated circuit per NEC 422.
Typical Amperage
20A small-appliance circuits, 50A for electric range, 20A for dishwasher, 20A for microwave (or 15A if shared with general lighting in older homes), 15A for refrigerator, 15A for garbage disposal.
Receptacle
NEMA 5-20R for countertop and small-appliance circuits (T-shaped neutral slot). NEMA 14-50R for electric range. Standard 5-15R for refrigerator and garbage disposal.

Typical 2026 pricing
$400 – $900 per dedicated circuit
A full kitchen remodel that adds all the dedicated circuits required by NEC 210.52(B) typically runs $2,500–$4,500. Single-circuit additions (e.g., adding a microwave dedicated circuit during a kitchen update) run $400–$900 depending on run length and whether existing wall finishes can be preserved. Fairfax County, Arlington, Alexandria, or Loudoun permit included.
Signs you need a dedicated circuit
- The kitchen breaker trips when the microwave runs while another appliance is on
- You're remodeling the kitchen and need to bring it up to current code
- The refrigerator is sharing a circuit with countertop outlets — modern code requires its own dedicated 15A circuit
- You're adding an electric range, induction cooktop, or wall oven to a kitchen previously set up for gas
- Garbage disposal cycles trip the breaker because it's sharing with the dishwasher
- Your countertop outlets are wired in series with only one 20A circuit — code requires at least two separate circuits
Our installation process
- 1
In-home assessment
We map your existing kitchen wiring, identify which appliances are sharing circuits, calculate the load against NEC 210.52(B) requirements, and provide a written quote with each circuit itemized.
- 2
Permit pull
Fairfax County, Arlington, Alexandria, Loudoun, Prince William, or wherever you are. We file under our master electrician license; no homeowner paperwork.
- 3
Wire runs from panel to kitchen
New circuits home-run from the main panel to each appliance location. Wherever possible we fish through existing walls; in finished spaces we coordinate with the homeowner on access points.
- 4
Receptacles and terminations
GFCI-protected NEMA 5-20R receptacles on countertop circuits per NEC 210.8(A). Tamper-resistant outlets per current code. Properly grounded and bonded to the panel.

Panel work
Install AFCI/GFCI breakers per current code requirements. AFCI is required on most new kitchen circuits in homes under recent NEC adoption.

Inspection
We schedule the local jurisdiction's electrical inspector and meet them on-site. First-visit pass rate is essentially 100% — kitchen circuits are well-defined code work.
Frequently asked questions
Why do I need TWO 20-amp small-appliance circuits in the kitchen?
NEC 210.52(B) requires it. The reasoning: kitchen countertops host high-current devices (toasters, coffee makers, mixers, instant pots) that frequently run simultaneously. One 20A circuit can't handle two ~12-amp devices running at the same time without nuisance tripping. Two circuits gives you 40 amps of countertop capacity split across multiple receptacles.
Does the refrigerator need its own dedicated circuit?
Best practice yes — current code recommends a dedicated 15A or 20A circuit for the refrigerator. The refrigerator's compressor cycling can cause voltage drops on a shared circuit that affect other appliances. Older kitchens (pre-1990s) often share the refrigerator with countertop outlets; this is grandfathered but not ideal.
What about the dishwasher and garbage disposal?
Modern code requires each to have its own dedicated 15A or 20A circuit. They often share a circuit in older kitchens, which leads to nuisance tripping when both run simultaneously. We split them as part of any kitchen circuit refresh.
Do I need to upgrade my panel to add kitchen dedicated circuits?
Depends on your existing panel capacity. If you have a 200-amp panel with spare breaker slots, we add the new circuits without upgrading. If you have a 100-amp panel that's already near capacity (common in 1960s–1970s NoVA homes), a panel upgrade is the right move first. We run the NEC 220 load calculation as part of the assessment.
How long does the work take?
Most kitchen dedicated-circuit projects complete in 1 day (3–6 circuits added). A full kitchen remodel with all NEC-compliant circuits is usually a 2-day job. The amount of wall access is the biggest variable — open construction (during remodel) is fastest; fishing through existing finished walls takes longer.
