Installing An Independent Electric Line For Your New UHD TV

Blog

Your new Ultra High Definition TV needs its own dedicated electric circuit. You cannot expect it to share a line with HD (HIgh Definition) or (gasp) SD (Standard Definition) components.

Adding a dedicated line will ensure that you are not overloading the existing line that is powering your decidedly lower tech TV and entertainment system. You can even add a surge protected outlet to allow your UHD TV to remain free of the communal power strip that supplies power to your current system.

What you will need

Surge protector outlet and open cover plate 

A 15 amp outlet will be sufficient for this task. You will need an open cover plate to protect the outlet instead of a traditional closed plate which only allows the two receptacles to be exposed.

An open plate will allow access to the center of the outlet, where an indicator light is installed to let you know it is working to protect your TV from power surges.

Single "old work" gang box

This is the box that holds the outlet inside the wall. An "old work " box is installed inside existing walls, while a "new work" outlet is attached to wall studs before walls are erected.

15 amp circuit breaker

Buy a breaker that is made by the manufacturer of your breaker box to ensure a proper fit.

Wire

You will need a three wire sheath of 14 gauge wire. The roll of wire will be marked "14-2". The length of wire needed will depend upon the distance from your proposed outlet to the breaker box. After measuring this distance, add several feet to the result for running the wire around obstructions and for connection purposes.

Tools

You'll need a wire cutter/stripper tool, a flashlight, screwdrivers (flat and Philips head), and a hole saw or utility knife to cut holes in the walls.

You will also need a drill with a 12 inch long (3/8") drill bit to drill through the floor and walls.

Preparing the outlet location

Hold the open side of the gang box against the wall and trace the outline with a pencil. Using a utility knife or hole saw (depending on the surface material), cut out the outline of the box in the wall.

Place the 12" drill bit inside the opening and drill down through the floor. Although you can't drill straight down, drill as upright as possible until you break through. 

Unless your breaker box is In the basement room directly under your new outlet, you will also need to drill through walls until you can access the breaker box.

Push out the knock out tab on the bottom of the gang box and wiggle it back and forth until it breaks free. Next, place  the gang box inside the wall and tighten the two diagonally placed screws until the box is secure inside the wall.

You will then begin to feed the sheath of wire through the knocked out hole and the floor until it clears the ceiling in the room below. Go downstairs and pull the wire sheath until it reaches the breaker box. You may need to pull it through holes made in the walls if the breaker box is in another room.

When you have reached the breaker box, get your flashlight ready, because you'll need to turn off the main breakers to your home. They will be located either at the top of the breaker panel or in a separate location.

When the house power is off, it's time to install the breaker.

Installing the breaker

Begin by removing the breaker box panel. When the panel is removed, pick an available slot inside the breaker box and punch out the tab that covers the slot. You will then punch out a round tab on the side of the breaker box that allows wiring to enter.

Remove 3/4" of insulation from each of the three wires inside the wire sheath, and push the wires through the round tab hole in the breaker box.

Insert the stripped ends of the white and green or copper wires into available slots in the white breaker bars inside the box, and tighten the screws to secure them.

Loop the black wire around the terminal screw of your new breaker and tighten the screw securely, then push the breaker into the empty slot until it clicks into place.

Restore the breaker box panel, but keep the power off.

Back at the outlet location 

Cut the wire sheath at a point that is 6 inches from the gang box, then strip the ends of the three wires as you did at the breaker box.

Connect the black wire to the brass terminal screw of the surge protector outlet, the white wire to the silver terminal, and the green or copper wire to the green terminal.

Place the sub-plate of your open cover plate around the outlet and push it into the gang box, securing it with the two screws provided.

Push the cover plate onto the sub-plate until it is secured, and turn on the main breakers and your newly installed breaker.

The indicator light on the surge protector outlet will light toinform you that you are ready for UHD TV. Contact a business, such as Alpine Electrical Construction LLC, for more information.

adding electric lights to your yard

How well is the outside of your home lighted? Do you have several areas around your home that become pitch black after the sun has fallen for the day? If you live in an area that does not get very much sunlight during the day, you probably have the same amount of success as I have had trying to use solar powered lights to light those dark areas. I finally broke down and contacted an electrician to help me run some power to the dark areas and install some much needed lights. He was able to give me a few suggestions that would not only brighten up my dark yard, but also look very nice from the street.
