You mounted your TV on the wall. It looks amazing — except for that ugly power cord dangling down to the nearest outlet. The obvious solution? Put an outlet right behind the TV. But before you grab a YouTube tutorial and start cutting drywall, there are serious electrical code requirements you need to understand.
Running standard power cables inside walls is a fire code violation in every state. Yes, even if "it worked fine for your neighbor." This guide covers the legal, safe ways to power a wall-mounted TV — and why cutting corners on electrical work is never worth the risk.
The #1 Rule: You Cannot Run Standard Power Cords Inside Walls
Let's get this out of the way immediately. The National Electrical Code (NEC) — adopted by Georgia and every other state — strictly prohibits running standard power cords (the cord that came with your TV) inside walls. This includes:
- ❌ Running the TV's power cord through a hole in the drywall
- ❌ Feeding an extension cord through the wall cavity
- ❌ Using a standard power strip inside the wall
- ❌ Running any non-rated cable through a wall cavity
⚠️ Why This Matters
Standard power cords are not rated for in-wall use. Inside a wall cavity, they can:
- Overheat — Wall insulation traps heat around the cable, potentially reaching ignition temperatures
- Be damaged by nails or screws — Future picture hanging or shelf installation could puncture the cable
- Create an undetectable fire — A smoldering cable inside a wall can burn for minutes before flames are visible
- Void your homeowner's insurance — If a fire starts from non-code-compliant wiring, your claim can be denied
What IS Code-Legal: Your Three Options
There are three code-compliant ways to get power behind your wall-mounted TV. Each has different costs, complexity, and results:
Option 1: In-Wall Power Kit (Most Popular)
An in-wall power kit (also called a power bridge or cable management kit) is the most common solution. It consists of two wall plates — one behind the TV and one near your existing outlet — connected by NEC-rated Romex (NM-B) cable run inside the wall.
| Component | Description |
|---|---|
| Upper plate (behind TV) | Recessed outlet with power receptacle + low-voltage pass-through for HDMI/coax |
| Lower plate (near existing outlet) | Power inlet that plugs into your existing wall outlet + low-voltage pass-through |
| In-wall cable | NM-B rated Romex wire (code-compliant for in-wall use) |
| Low-voltage cables | HDMI, coax, Ethernet pass-through (these CAN legally run inside walls) |
Cost: $50–$120 for the kit + $150–$300 for professional installation
Difficulty: Moderate DIY (requires cutting drywall and fishing cable)
Result: Clean, code-compliant, fully concealed power and signal cables
💡 Important Distinction
In-wall power kits use pre-wired NM-B rated cable that meets NEC requirements. This is fundamentally different from running your TV's power cord through the wall. The rated cable is designed for in-wall temperatures and won't create fire hazards. Look for kits that are UL-listed — this is your guarantee of code compliance.
Option 2: New Dedicated Outlet (Best Solution)
The gold standard: have a licensed electrician install a brand-new outlet directly behind where your TV will hang. This involves:
- Running new NM-B Romex from your electrical panel or an existing nearby circuit
- Installing a recessed outlet box (sits flush or behind the wall surface so the TV can mount flat)
- Adding a separate low-voltage bracket for HDMI/signal cables
Cost: $200–$500 depending on distance from panel and wall type
Difficulty: Requires licensed electrician (not DIY)
Result: Permanent, dedicated circuit — the cleanest and most reliable solution
Option 3: Surface-Mounted Raceway (No Wall Cutting)
If you can't or don't want to cut into walls (renters, brick walls, concrete), a paintable cable raceway runs along the wall surface from your outlet to the TV.
Cost: $15–$40 for the raceway kit
Difficulty: Easy DIY
Result: Visible but tidy — not as clean as in-wall solutions, but code-compliant and non-destructive
Low-Voltage vs. High-Voltage: Know the Difference
This distinction is critical for understanding what you can and can't run inside walls:
| Cable Type | Voltage | Can Run Inside Walls? | Examples |
|---|---|---|---|
| Low-voltage signal cables | Under 50V | ✅ Yes — no restrictions | HDMI, coax, Ethernet, speaker wire, USB |
| NM-B rated Romex | 120V | ✅ Yes — designed for in-wall use | Dedicated outlet wiring, in-wall power kits |
| Standard power cords | 120V | ❌ NO — NEC violation | TV power cord, extension cords, power strips |
Key takeaway: You can freely run HDMI, Ethernet, and coax cables inside walls. It's only the power cable that requires code-rated solutions. This is why many wire concealment installations combine a surface or in-wall power solution with fully concealed low-voltage signal cables.

Georgia-Specific Electrical Code Requirements
Georgia follows the National Electrical Code (NEC) with state-specific amendments. Here's what matters for TV outlet installation:
- Permit requirements: Adding a new electrical circuit typically requires a permit in most Georgia counties. In-wall power kits that connect to existing outlets generally don't require permits, but check with your local building department.
- Licensed electrician: Georgia requires a licensed electrician for new circuit installation. In-wall power kit installation falls in a gray area — it's technically connecting to an existing circuit, but many jurisdictions recommend professional installation.
- Inspection: New circuits added during permitted work will be inspected. This protects you — an inspector verifies everything is safe and code-compliant.
- Home sale implications: Non-code-compliant electrical work discovered during a home inspection can delay or kill a sale. Buyers (and their inspectors) will flag power cords running through walls.
In-Wall Power Kit Installation: Step by Step
Here's what professional installation of an in-wall power kit involves:
- Location planning — Mark the upper plate position (behind TV) and lower plate position (near existing outlet). Verify no fire blocks, plumbing, or electrical wiring in the wall cavity between them.
- Stud detection — Ensure both plate locations are between studs (not on a stud). The wall cavity must be clear for cable routing.
- Cut openings — Use a drywall saw to cut precise openings for both old-work boxes.
- Fish cable — Route the NM-B power cable and low-voltage cables from the upper opening down to the lower opening through the wall cavity.
- Install plates — Mount both wall plates, connect the wiring, and secure the old-work boxes.
- Test — Verify power delivery, test GFCI protection if applicable, and confirm all connections are secure.
Common Installation Challenges
- Fire blocks: Horizontal 2x4s between studs (required in many homes) block cable routing. They must be drilled through — which requires knowing their exact location.
- Insulated walls: Exterior walls with insulation make cable fishing significantly harder.
- Brick or concrete walls: In-wall kits don't work on solid masonry. Surface raceways or conduit are the alternatives.
- Multiple stories: Running cable between floors adds complexity and may require opening additional access points.
Why Professional Installation Matters for Electrical Work
We're not just saying this because we offer outlet installation services. Electrical work is the one area where DIY mistakes have the most severe consequences:
- Fire risk: Improper wiring connections are a leading cause of residential fires. A loose wire nut or incorrect gauge cable can smolder for weeks before igniting.
- Insurance: Non-permitted electrical work can void your homeowner's insurance coverage for fire damage. If an adjuster finds non-code wiring, your claim may be denied.
- Resale impact: Home inspectors flag improper electrical work. Buyers will demand remediation or reduce their offer.
- Code compliance: Professional installers know current NEC requirements and local Georgia amendments. What was acceptable 10 years ago may not meet current code.
- Warranty: Our outlet installations include a 5-year workmanship warranty. DIY electrical work has zero safety net.
Cost Comparison: DIY vs. Professional Outlet Installation
| Factor | DIY In-Wall Kit | Professional In-Wall Kit | New Dedicated Outlet |
|---|---|---|---|
| Materials | $50–$120 | Included | Included |
| Labor | Your time (2–4 hrs) | $150–$300 | $200–$500 |
| Tools needed | $30–$80 | $0 | $0 |
| Permit (if required) | $50–$100 | Handled by installer | Handled by electrician |
| Code compliance | ⚠️ Uncertain | ✅ Guaranteed | ✅ Guaranteed |
| Warranty | ❌ None | ✅ 5 years | ✅ Electrician's warranty |
| Total | $130–$300 | $199–$349 | $250–$550 |
The price difference between DIY and professional installation is minimal — and professional installation includes code compliance, warranty, and the peace of mind that your home's electrical system is safe.

Frequently Asked Questions
Can you run a TV power cord through the wall?
No. Running a standard TV power cord inside a wall cavity violates the National Electrical Code (NEC) and is a fire hazard. Standard power cords are not rated for in-wall temperatures and can overheat when surrounded by insulation. Use a UL-listed in-wall power kit with NM-B rated cable, or have a licensed electrician install a dedicated outlet behind the TV.
How much does it cost to add an outlet behind a TV?
An in-wall power kit with professional installation costs $199–$349. A new dedicated outlet installed by a licensed electrician costs $250–$550 depending on distance from the electrical panel and wall type. Bundling outlet installation with TV mounting service typically reduces overall cost compared to separate appointments.
Do I need an electrician to install an outlet behind my TV?
For a new dedicated circuit, yes — Georgia requires a licensed electrician. For in-wall power kits that connect to existing outlets, professional installation is strongly recommended but may not legally require an electrician in all jurisdictions. However, given the fire safety implications of improper electrical work, professional installation is always the smart choice.
Can I use an extension cord behind a wall-mounted TV?
You should never run an extension cord inside a wall. For surface use, a short extension cord from a nearby outlet is technically functional but creates visible cable clutter that defeats the purpose of wall mounting. The better solutions are an in-wall power kit, a new dedicated outlet, or a paintable surface raceway.
What is the best in-wall power kit for a TV?
Look for UL-listed kits that include both power (NM-B rated cable) and low-voltage pass-throughs for HDMI and coax. Popular options include the PowerBridge TWO-CK and the Echogear EGAV-WMPK1. The key features are recessed outlet design (so the TV sits flat), sufficient cable pass-through space, and code-compliant power wiring.
