Does Your Kitchen Remodel Need an Electrical Panel Upgrade?
Keystone Extreme
Keystone Extreme Guide
A kitchen remodel asks more of your electrical system than any other room in the house. New circuits for the countertop receptacles, a dedicated line for the dishwasher, another for the disposal, often one for the microwave and one for the range. In a house built before the late nineteen nineties, that list frequently runs out of panel before it runs out of wall.
This is the part of a renovation homeowners find out about late, usually when the electrician opens the panel on day two. Knowing what a modern kitchen requires, and what your panel can actually carry, turns a mid project surprise into a line on the estimate.

Why Older Marietta Homes Run Out of Panel
The electrical requirements for a kitchen have grown steadily for thirty years. A kitchen wired in 1975 might have one general circuit feeding the counter outlets, the lights and the refrigerator together. A kitchen wired to current code has two twenty amp circuits serving the countertop receptacles alone, before you add anything else.
Add a dishwasher, a disposal, a built in microwave and an electric range, and most of those want a circuit of their own. The panel does not care how nice your new cabinets are. It cares how many breaker spaces are left and how much capacity the service has, and in a hundred amp panel that is already feeding a heat pump and a water heater, the honest answer is often not enough.
Dedicated circuits
Dishwasher, disposal, microwave and range each generally want their own circuit. Manufacturers specify it, and sharing one is the usual cause of a breaker that trips every time two appliances run together.
Panel capacity
A full panel is not the same as an undersized service. Sometimes the fix is a subpanel for the kitchen. Sometimes the service itself has to go from one hundred to two hundred amps.
GFCI and AFCI protection
Countertop receptacles need ground fault protection, and kitchen circuits generally need arc fault protection as well. Both are handled at the panel or at the device, and both get checked at inspection.
Signs Your Panel Will Come Up in the Permit Review
You do not need to open the panel yourself to have a strong idea of where this is heading. These are the things we look for on a first visit.
- The service is one hundred amps and the house has electric heat or an electric range
- Every breaker space is occupied, or tandem breakers have been added to make room
- The panel is a brand with a known recall history, which an inspector will flag
- Two prong outlets anywhere in the kitchen, meaning no equipment ground on that run
- A single breaker that trips when the microwave and the toaster run together
- Aluminum branch wiring, common in homes built in the late sixties and early seventies
- No ground fault protection at the counter receptacles today
- A disposal or dishwasher sharing a circuit with the countertop outlets
- Knob and tube or cloth sheathed wiring visible in the basement or crawl space
- You are adding an island, which needs at least one receptacle of its own
Georgia adopts the National Electrical Code with state amendments, and the version in force is the one that applies when you pull the permit. That matters because the requirements have tightened over several cycles. Work done legally in 1998 can still be entirely legal to leave alone, and at the same time cannot be extended as it is. This is why a remodel sometimes triggers an upgrade that a repair would not.
What an Upgrade Actually Costs You in Time
The money is a conversation for your estimate, because it depends on the service, the meter location and the utility. The schedule is more predictable, and it is usually the part people have not planned for.
A subpanel added for the kitchen is typically a day of work and fits inside the rough in week with no effect on the finish date. A full service upgrade from one hundred to two hundred amps is different: it involves the utility, a separate inspection, and a planned power outage for part of a day. Booked at the start of the project it costs you nothing in schedule. Discovered in week three, it can stall tile and cabinets for a week while everyone waits on a utility appointment.
Note: Ask for the panel to be opened and photographed during the estimate, not on the first day of work. It takes ten minutes, it is the cheapest information in the whole project, and it is the difference between a number on your estimate and a change order in week three.

Not Sure What Your Panel Can Carry?
We look at the panel, count the circuits your new kitchen will need, and tell you before the work starts whether a subpanel or a service upgrade is in the plan. Licensed general contractor, Marietta and Metro Atlanta.
Frequently Asked Questions About Kitchen Remodels and Electrical Panels
No. Plenty of kitchens get new circuits without touching the service, especially where the panel has spare spaces and the house is already on two hundred amps. The upgrade comes up when the panel is full or the service is too small for what the new kitchen adds.
A subpanel adds breaker spaces that are fed from your existing service, so it solves a space problem but not a capacity problem. A service upgrade raises the capacity itself, usually from one hundred to two hundred amps, and involves the utility and a separate inspection.
For a subpanel, briefly. For a full service upgrade, expect part of a day without power while the meter and service entrance are changed out. We schedule that for a day you have been told about in advance rather than whenever the crew gets to it.
Often yes for the parts you are not touching. Existing work that was legal when it was installed can usually stay. What you generally cannot do is extend old wiring to serve the new kitchen, which is where the new circuits and the panel question come from.
During the estimate, before anything is demolished. Opening the panel takes ten minutes and tells us whether an upgrade belongs in your number from the start. Finding out in week three is what turns a planned cost into a change order and a delay.
