The clean look of a wall-mounted TV with no visible cord comes from one thing: a real electrical outlet installed in the wall behind the screen, wired with materials rated for use inside walls. That outlet is fed either from a nearby existing circuit or from a new circuit, and it sits in a recessed box so the plug stays flat against the wall. What it does not come from is pushing the TV’s power cord, or an extension cord, through a hole in the drywall. Ordinary cords are not rated to be concealed in walls, and doing it creates a fire risk that no inspector will accept.
For homeowners across Gwinnett and metro Atlanta, this project usually comes up when a new TV goes over a fireplace, onto a living room feature wall, or into a bedroom or finished basement. The work is not complicated for a licensed electrician, but it involves planning a few details before anyone cuts into drywall: exactly where the outlet goes, how power will reach it, whether the circuit can take the extra load, and what else will be installed behind the screen. Getting those decisions right the first time is what keeps the finished wall looking clean.
Why an Ordinary Power Cord Cannot Go Inside the Wall
The TV’s cord, a power strip cord, and extension cords are flexible cords designed to be out in the open where heat can escape and damage can be seen. The National Electrical Code, published by the NFPA as NFPA 70, the National Electrical Code, does not allow flexible cords to be run through walls or concealed behind wall surfaces as a substitute for permanent wiring. Inside a wall, a cord can be pinched by framing or fasteners, can overheat with no airflow, and sits right next to wood framing and insulation where a failure would go unnoticed.
Permanent wiring is different. The cable used inside walls is rated for concealed installation, sized to the breaker protecting it, and terminated in secured electrical boxes where every connection stays accessible. That is the path to a hidden cord that is actually safe. The NFPA’s guidance on electrical safety in the home is a good reminder of why extension cords and improvised wiring are among the habits worth retiring.
Planning the Outlet Location Before the TV Goes Up
Place the outlet inside the TV’s footprint
The outlet needs to sit where the screen will fully cover it, usually a little above the center of the TV, so the short power cord reaches without a loop hanging down. Before scheduling, it helps to know the TV’s size, the mount you plan to use, and the height of the screen’s center. Many mounts have a large plate that covers the middle of the wall, so the outlet is often placed just above or beside that plate. Measuring and marking the TV outline on the wall with painter’s tape is a simple way to show the electrician exactly where the screen will land.
Choose a recessed outlet box
A standard outlet pushes the plug straight out from the wall, which can hold a slim TV away from the mount or bend the cord. A recessed box sets the receptacle back into the wall so the plug sits flush or below the wall surface. For most flat-panel TVs, this is the detail that makes the difference between a flush install and a screen that tilts forward.
Account for what else lives behind the screen
Sound bars, streaming devices, and cable boxes often need power too. Some homeowners add a second outlet lower on the wall, near a console or shelf, and keep all components off the wall entirely. Think through the full setup now, because adding another outlet later means opening the wall again. The HDMI, speaker, and network cables for that equipment are low-voltage cabling, which is separate work. Kalahari installs the electrical outlet; the TV mounting and any low-voltage cabling should be handled by the homeowner or an AV installer. Power and low-voltage cables should not share the same box unless it is designed with a divider, so your electrician will keep them apart.
Check the wall itself
The wall construction shapes the job. Standard drywall over wood studs is the easiest. Plaster and lath, brick, stone veneer, and walls above fireplaces take more planning, since the space above a fireplace can include framing, a chimney chase, or a flue that limits where wiring can go. Insulated exterior walls and firestops between studs can also require extra access holes.
The Wiring Options an Electrician Will Consider
Extending an existing circuit
The most common approach is to extend power from an existing outlet on the same wall, often the one directly below the TV. The electrician confirms the circuit has enough capacity for the TV and whatever else it already serves, then runs rated cable up inside the wall cavity to the new recessed box. How much a circuit can safely carry depends on what is already connected to it, which our guide on how many outlets can be on one circuit explains in more detail.
Running a new circuit
If the nearby circuits are already loaded, as they often are in family rooms with a lot of electronics, a new circuit from the panel may make more sense. That involves a longer wiring route through an attic, basement, or crawl space, plus a new breaker. Our electrical wiring services cover that kind of new circuit work. In some older Gwinnett homes, the panel may be full or undersized for new circuits, which is covered in our article on whether you can add breakers to an electrical panel.
Using a listed in-wall power kit
Some products are designed specifically for this situation. They pair a recessed receptacle behind the TV with a power inlet near the floor, connected by cable rated for in-wall use. When a kit is listed by a recognized testing lab and installed according to its instructions, it can provide a code-compliant path for power without tapping directly into the existing circuit. An electrician can tell you whether a kit or permanent wiring is the better fit for your wall and your equipment.
Whichever option fits, the outlet itself is the heart of the job. Kalahari’s outlet installation and replacement services include the recessed box, the receptacle, the connections, and testing at the end.
Code, Permits, and Protection to Expect
New or extended circuits serving living rooms, family rooms, bedrooms, and most other living areas generally require arc-fault protection, or AFCI, which detects dangerous arcing in wiring and shuts the circuit off. Depending on what already protects the circuit, that may mean a combination AFCI breaker in the panel or an AFCI receptacle at the first outlet on the run. New receptacles in homes also generally need to be tamper-resistant, with internal shutters that block objects other than a plug.
In Georgia, extending a circuit or adding a new one is typically work that calls for a permit from the county or city building department, such as Gwinnett County or your city, followed by an inspection. A licensed electrician will confirm what your jurisdiction requires and pull the permit when one is needed. Homeowners throughout eastern Gwinnett looking for an electrician in Dacula can count on Kalahari to handle the permit side as part of the electrical scope.
Surge protection is worth a thought too. A recessed box behind a TV usually leaves no room for a bulky plug-in surge strip. Georgia’s thunderstorm season makes surge protection a real consideration for expensive electronics, and a whole-home surge protector installed at the panel covers the TV along with everything else in the house. Our guide to whole-home surge protectors explains how that works.
What Drives Cost and Timing
Pricing varies, and the main factors are clear. The simplest job is extending an existing, lightly loaded circuit on the same wall, through standard drywall, with an open stud bay above the outlet below. Costs rise with a new circuit from the panel, long wiring routes, limited attic or crawl space access, plaster, masonry, or fireplace walls, horizontal runs that cross multiple studs, extra outlets for components, and permit fees. If the panel needs work to accept a new breaker, that is a larger project on its own.
Timing follows the same pattern. A straightforward extension on an accessible wall is often completed in part of a day, while a new circuit or a difficult wall takes longer. Permit and inspection scheduling add calendar time. Electricians keep wall openings as small as practical, but some patching is normal, and drywall finishing and painting are usually handled afterward by the homeowner or a painter.
When you request an estimate, have a few details ready: the TV size and mount type, the planned height, the wall construction if you know it, what is on the other side of the wall, where your electrical panel is, and whether there is attic or basement access above or below that wall. Photos of the wall and the nearest outlet help as well. ENERGY STAR’s page on certified televisions is also useful if you are still choosing a TV and want to compare efficiency before the outlet goes in.
A Clean Wall Starts With the Right Outlet
The finished look you want, with the TV on the wall and no cord in sight, depends on a properly installed outlet behind the screen, not on hiding a cord in the drywall. Plan the location with the TV’s footprint in mind, choose a recessed box, think through the components you will add, and let a licensed electrician confirm the circuit and the permit before the mount goes up. Scheduling the electrical work first also makes the mounting step easier for whoever handles it.

Frequently Asked Questions
Can I run my TV’s power cord inside the wall to hide it?
No. Ordinary power cords and extension cords are not rated for concealed installation, and the National Electrical Code does not allow them to be run through walls in place of permanent wiring. The safe option is a new outlet behind the TV, wired with in-wall rated cable, or a listed in-wall power kit installed according to its instructions.
Do I need a permit to add an outlet behind my TV in Georgia?
Extending an existing circuit or adding a new one typically requires a permit and inspection from your county or city building department. A licensed electrician will confirm the requirement for your address and pull the permit when needed.
What kind of outlet works best behind a wall-mounted TV?
A tamper-resistant receptacle in a recessed box is the usual choice, because it lets the plug sit flush so the TV can hang tight to the wall. The circuit also generally needs AFCI protection in living areas and bedrooms.
Who handles the TV mounting and HDMI cables?
Kalahari handles only the electrical work: the outlet, the wiring to it, and any circuit or permit needs. TV mounting and low-voltage cables such as HDMI are handled separately by the homeowner or an AV installer.
How long does it take to install an outlet behind a TV?
A simple extension from an existing outlet on an accessible drywall wall is often part of a day. New circuits, difficult walls, or limited attic and crawl space access take longer, and permits add scheduling time.
