How to Run Overhead Electrical Wire to Garage: Learn Here Best Ideas


If you’re remodeling an existing garage or making a brand new one, you have to decide whether you would like to keep the walls open or seal them using a Gypsum board. So, following the guidelines we’ve provided here is essential if you’d like to keep the ceiling and walls unfinished. In this article, I will go over the best way to run overhead electrical wire to the garage. In a fully-constructed garage or home, you will need the wall covered with a solid covering like sheetrock. Drywall or even wooden panels can shield the wiring from harm. The best way to ensure secure and legal exterior wiring is to frame the wiring to support and protect the cables.

That means lines must not be able to pass through joists or studs. Ensure that all wires are secured to walls, ceiling panels, studs, and posts to stop the misuse of cables. This article will look at the best way to run overhead electrical wire to garage.

How to run overhead electrical wire to garage

Underground electrical lines running to detached garages due to obstructions like driveways or patios could be a nightmare. A common and effective solution to this problem is installing overhead wires. The process of transferring electricity through the central panel in your home to your garage detached by wires that run above a certain level above the floor is known as are referred to as the overhead wire. Now we will show you how to run overhead electrical wire to garage.

Step 1

The running wires that run through the rigid conduit (RMC) are slightly more costly than burying underground feeder cables (UF); however, they will save labor. It is because the top of the RMC must be six inches from the level of the ground, and UF is required to be buried at least 12 inches (deeper in certain circumstances). Six inches more trench depth might not be a huge difference. However, it can be exhausting a long time work, especially when you’re dealing with rocky soil and hard clay or lots of roots.

Step 2

Utilize a mattock to dig the trench. A narrower head means less dirt to be removed and less work to put back. Cut out sections of sod with spades to quickly patch the lawn. There are various things to think about when designing the path from home up to your shed. The smaller the trench is, it’s less excavation you’ll need to complete. However, you should figure out where you’ll connect to the power within the home and how easy it is to connect it. In certain situations, it’s possible to do a bit more digging may prevent the need to cut into the basement ceiling. Begin by finding an electrical source, such as the main panel, a wall box or outlet or any other electrical box.

Step 3

After you’ve mapped out the route, you can measure the amount of conduit and wire you’ll need, then go towards the local hardware shop or the home center. Then add another 10 feet on top of the wire or pipe to ensure you have enough. It’s recommended to drill a hole into the structure before beginning digging if you encounter obstacles and need to find a new spot. If you’re sure of the location of the exit, make an excavation from home towards the shed. If you’re digging across the lawn, take some sodas wide as a spade from the area and save it to use again after burying the pipe. Use a mattock or narrow spade to create the trench. Put the dirt in plastic tarps to ensure you don’t have to pull it off the lawn later.

Step 4

The flexible conduit will rise out of the ground into a fitting referred to as”LB. “LB.” The LB comes with a cover that can be removed, making it easier to pull the wire by removing an abrupt right-angle turn. The most challenging aspect of this project is fixing these LBs and connecting them with the metal boxes in the shed and in the house. Generally, you need to select a location for the box and then determine the distance of electric metallic tubing (EMT) that will be required to go from the rear of the LB to the chest. If you’re installing the crawl space or basement and the length of the conduit is not usually a concern.

Step 5

Begin by drilling a small hole using an extended bit to ensure you’re in the right place. After that, prepare a 1-inch hole to accommodate the conduit, the LB, and the line. Install a 1/2-in. Conduit connector to the back of the LB and connect a piece of 1/2-in. EMT that is large enough to easily fit into the box located in the crawl space or basement. Once you’ve attached your LB onto the wall, enter and secure the conduit connector and metal electrical box at the opposite end that connects to the EMT. This is where you’ll connect from the wiring in your home to the wiring of the shed. Inside the hut, screw an 8 x 4 in. square metal box on the inside is the end of the screw.

Step 6

The conduit’s passage through the wall and into one of the inside boxes is perhaps the most challenging step. The 10 feet lengths of RMC are threaded at both ends and have a coupling at the other end. Begin by bending the pipe and then threading an LB onto the other end. Then, incorporate the lines until you reach the opposite end. You’ll then be able to cut the final piece of conduit and join it with the LB by using a compression connector.

Step 7

Attach the LB temporarily onto the building. Take measurements across the entire trench from bottom to top of the LB fitting. Add 3/4-in for the threads inserted into the LB and subtract the bend allowance on the bender (usually six inches) from this measurement to calculate the bend. Make a note of the distance on your piece conduit and measure it from the end using threads that aren’t bare.

Step 8

Retract the conduit bender until the conduit is straight up. A magnetic level lets one know when they’ve achieved an ideal 90-degree bend. Bring the bent pipe back to the trench, and then screw it onto the LB onto the top. The mark should be aligned on the conduit to the bender’s arrow.
Install the conduit above ground to enable tightening the connections more easily. The pipe should be supported by 2x4s until you’ve connected every except the final section. Conduit lengths until you get to the house.

Step 9

Bend the final piece of conduit upwards and then cut it down to fit inside the connector for compression. Begin by measuring the distance from the end piece of pipe to the home wall. If the LB is kept from the border with siding, subtract that distance from your measurement. Then add 3/4-in. to the threading and remove it for the bend. Make adjustments to the size based on how far the LB extends beyond the wall. The last piece of conduit begins with the bare threads.

Step 10

Place the bent conduit to mark it to cut, starting with the bearing threads. Because there aren’t any threads on the other end of the pipe, you can screw a compression fitting into LB and connect your conduit. The threaded part of the conduit is not the other end of the coupling as you bend it. Cut the tube, marking it and cutting it using a hacksaw. Get rid of burrs on the inside pipes by smoothing the surface with an emery board or inserting the handleless metal of pliers in the tube and then twisting.

Finish the conduit run by threading the final section of the tube. It is necessary to raise the last piece of line to make clearance while you turn and bend the pipe. After that, insert the other pipe’s end into the connector, and put the compression nut in place using an adjustable wrench. Then, wrap a conduit strap around the conduit and screw it onto the house to secure the pipe. Make sure to press a rope of “duct seal” around the top of the LB to ensure that water is kept out.

Step 11

Take off the covers of the LBs, and then push a fishing tape into the pipe. The fish tape is fed across the conduit. The wires should be looped through the fish tape before wrapping them in electrical tape. Wrap the hook around the video to ensure it doesn’t get caught. Make sure you use stranded wire, not wire that is solid wire. Pull these wires across the conduit. There will be two white and black wires to make one circuit or more if you are planning to wire a three-way switch to the house or add multiple courses. Choose THWN-2, 14 gauge Stranded wire if you are getting the power of a circuit with 15 amps or THWN-2, 12 gauge wire that is stranded to pull a 20 amp circuit. You should leave enough wire on each end to extend to the metal box, plus 12 inches.


We have all the details required to unravel the mystery of how to run overhead electrical wire to garage. Ensure you check the local building codes to ensure you can place electrical outlets above. Regulations and conditions differ from one municipality to another. If you need assistance installing poles, pipes, or cables, engage an expert.
