02 — Same for Same
What Same for Same Looks Like Behind the Cabinet
A replacement row is only approved when the new appliance fits the existing connection, and the installation sheet determines that. Section E4101.2 of the 2021 Virginia Residential Code says appliances are installed according to the manufacturer’s instructions, so a requirement printed in the sheet becomes part of passing inspection.
One GE dishwasher guide calls for its own grounded 15- or 20-amp circuit and says to call a licensed electrician if the supply falls short.
When a swap turns into wiring work
The old dishwasher was hardwired and the new one ships for a cord kit, or the reverse. The existing outlet sits where the new sheet will not accept it. A range hood comes down, and an over-the-range microwave goes up, with its outlet somewhere the kitchen has never had one.
03 — Dishwashers & Disposals
Dishwashers and Disposals: Cord Length, Outlet Location, GFCI
Virginia’s code allows a flexible cord only where the appliance is listed for one and the manufacturer’s instructions identify the cord as suitable. Receptacles for corded appliances must be accessible and located so that the cord is not damaged.
Cord lengths in Table E4101.3
A built-in dishwasher cord runs 36 to 78 inches, measured from the face of the plug to the plane of the appliance’s back. An in-sink waste disposal cord runs 18 to 36 inches. An outlet placed for either appliance has to work within that window.
Where the dishwasher outlet goes
A built-in dishwasher’s receptacle belongs in the space adjacent to the dishwasher, often the sink base cabinet. Where the cord passes through an opening, the code calls for a bushing, grommet, or other approved protection.
GFCI on the dishwasher circuit
Section E3902.11 requires ground-fault protection for outlets on branch circuits rated 150 volts or less to ground that supply dishwashers in homes. The wording covers the outlet supplying the dishwasher, so hardwired units count along with corded ones.
04 — Hoods & Microwaves
Range Hoods and Over-the-Range Microwaves
A receptacle for a cord-and-plug-connected range hood must be supplied by an individual branch circuit, and the hood’s cord falls between 18 and 48 inches. When a replacement hood arrives with a cord, and the old one was wired in, the outlet and its circuit are planned together.
Over-the-range microwaves follow their own sheets. A Whirlpool microwave hood guide requires a 120-volt, 15- or 20-amp supply and recommends a time-delay breaker or fuse and a separate circuit serving only the microwave. It also says the grounded three-prong outlet must be inside the upper cabinet, with the cord threaded through the bottom of the cabinet. We wire the cabinet outlet to match.

How We Take a Kitchen Appliance Job
Share the installation sheet
Model number or installation sheet, plus pictures of the cabinet and panel label, for a written installation estimate.
Scope check
Install or replacement under Chesapeake’s guide, and what the code and sheet call for.
Permit and scheduling
We file any electrical permit and time the work with your appliance installer.
Wiring
Circuit run, breaker sized to the nameplate, supply set where the sheet and code place it, GFCI where required.
Ready before the installer arrives
City inspection is completed after a permit is filed; the connection is then tested and left live.
06 — Disconnects
The Shutoff: Plug, Lockable Breaker, or Switch in Sight
Table E4101.5 of Virginia’s code sets out how appliances are disconnected, and the right answer depends on how the appliance connects. For a corded appliance, the plug is the disconnect, so its receptacle has to stay accessible.
For a hardwired dishwasher, that usually means a lockable breaker in the panel or a disconnect within sight, unless the unit’s own switch qualifies under the table.
07 — Breaker Sizing
Matching the Breaker to the New Appliance
The breaker follows the appliance’s rating and listing. What fed the old unit tells you nothing about what the new one needs. One over-the-range microwave guide lists a rating of 120 volts and 15 amps and calls for a 15- to 20-amp circuit. We read the nameplate and the installation sheet, then match the breaker and wire. In an older kitchen, an electrical safety inspection can show whether rewiring should come first.

How Castles Handles Chesapeake Kitchen Circuits
The appliance’s own sheet is part of the code here
Virginia’s code makes the manufacturer’s installation instructions part of what the inspector checks.
The permit question is answered before the appliance lands
A same-for-same swap and a new circuit sit on opposite sides of Chesapeake’s guide, and we say which one you have.
