A PowerBridge is a UL-listed in-wall cable management kit that safely routes both power and low-voltage cables from an existing outlet to a wall-mounted TV, ensuring compliance with NEC Article 400.7 and preventing fire hazards.
What's the deal with those messy TV cables?
A PowerBridge kit solves the common problem of messy TV cables by providing a code-compliant way to route both power and low-voltage cables through the wall.
Mounting a TV flush to the wall looks sleek, but those dangling power and AV cables? They ruin everything. Standard power cords aren't built for in-wall use—they violate NFPA 70 (NEC Article 400.8) and create serious fire risks. A PowerBridge kit fixes this by swapping out the factory power cord for a UL-listed, in-wall-rated power module and adding a separate sleeve for HDMI and other low-voltage cables. The kit links a new outlet behind the TV to a nearby power source using NM-B cable (Romex) or THHN conductors in conduit—all while keeping things fully code-compliant. Fun fact: most kits now bundle both the power module and low-voltage sleeve together. Handy, right?
How do I actually install one?
Installing a PowerBridge involves cutting two drywall openings, running a UL-listed power module between them, and using a separate sleeve for low-voltage cables.
This isn’t a beginner project—you’ll need basic electrical know-how, drywall repair skills, and a willingness to follow local codes. Always flip the breaker off first. Here’s how it usually goes down:
- Map out the route: Grab a stud finder and check for studs, plumbing, and wiring between where you’ll mount the TV and your nearest outlet. Mark a vertical path at least 1.5 inches wide to dodge studs. If you hit a stud, drill a 1-inch hole to thread the cables through.
- Cut the openings: At the TV spot, cut a single-gang opening (4" x 4") for the power outlet box. Near the source outlet, cut another single-gang opening for the power feed box. Most kits come with templates to make this easier.
- Thread the power module: Feed the pre-wired, flexible power module (UL-listed) from the source box to the TV box. Hook it up to the existing outlet with a UL-listed twist-on or push-in connector. Pop the module into the TV box—it’s designed to take a standard single-gang outlet cover.
- Add the low-voltage sleeve: Run the hollow sleeve alongside the power module between the two boxes. Later, use a fish tape to pull HDMI, Ethernet, or optical cables through it.
- Finish it up: Secure both boxes with screws, slap on the included wall plates, and turn the power back on. Tuck any extra cable length into a cable management box behind the TV to keep things tidy.
Watch out for rookie mistakes: using non-rated cables, cramming too much into the sleeve, or forgetting to anchor boxes to studs. If electrical work makes you nervous, OSHA suggests calling a licensed electrician—safety first!
What if my wall’s too tricky for a PowerBridge?
For complex installations, alternatives include using a surface-mount raceway or hiring an electrician to install a new in-wall outlet.
Got a wall full of obstructions or zero drywall repair experience? Try these instead:
- Surface-mount raceway: Run a paintable PVC or aluminum raceway from the TV to the outlet. Use 1/2-inch or 3/4-inch raceways to keep power and low-voltage cables separate. No drywall cutting needed—just follow the manufacturer’s instructions to stay code-compliant. Paint it to blend in, and boom, no one will notice.
- Call in a pro: Hire an electrician to install a new dedicated outlet behind the TV. They’ll run NM-B cable from the circuit panel or a nearby junction box (permits and inspections required in most areas). They’ll use an in-wall-rated single-gang box like a Carlon B117. Expect to pay between $250 and $600, depending on how far they have to go.
What if a PowerBridge just won’t work in my space?
If a PowerBridge isn’t feasible, use a surface-mount raceway or hire an electrician to install a new outlet behind the TV.
Some homes have walls packed with insulation, plumbing, or studs that block a clean cable path. In cases like this, skip sketchy hacks like shoving factory cords into the wall or using extension cords. Instead, try these safer options:
- Surface-mount cord management: Grab a Leviton CordMate II or similar kit. These use adhesive-backed channels and covers to hide cords while keeping them accessible. Perfect for renters or places where drilling isn’t an option. Paint the channel to match your wall—no one will know it’s there.
- PowerBridge with an external power supply: Some TVs (like VESA-compliant mounts with power input ports) let you use an external power supply. Run a short, UL-listed power cord from the TV to an outlet, then only thread low-voltage cables through the sleeve. You cut down on in-wall electrical components without sacrificing safety.
Still unsure? Call a licensed electrician. They’ll inspect your wall and point you to a solution that meets NEC standards.
How can I keep cables under control long-term?
Prevent cable clutter and safety hazards by planning cable routes before mounting your TV and using code-compliant products.
Don’t wait until after the TV’s up to deal with cables. Nip problems in the bud during installation:
- Never stuff factory cords into walls: Those cords aren’t rated for in-wall use and violate OSHA electrical safety guidelines. The fire risk is real, especially in tight wall cavities where heat can build up.
- Stick to UL-listed kits: Look for labels like “UL 2449” or “NEC 400.7 compliant.” Solid choices include Monoprice PowerBridge, Wiremold PowerBridge, or similar products from home centers.
- Keep power and data cables apart: Even in a sleeve, give power cables at least 2 inches of space from HDMI or other low-voltage cables to avoid interference. A divider or separate sleeves can help.
- Think ahead: Install a deeper outlet box (like a 2.75" deep one) to make room for future gadgets like soundbars or streaming boxes. If you’re planning to expand, run a second sleeve now to save hassle later.
