How To Run Overhead Electrical Wire To Garage

How To Run Overhead Electrical Wire To Garage

Due to barriers such as patios or roads, running underground electrical connections to a detached garage can be a pain. Running overhead wire is a frequent and effective solution to this problem. Most residences will have an attached garage with power and electricity already installed.

You’ll have to run power to a detached garage or shed separately if your home has one. Running an overhead electrical cable from your house to your garage is a common option.

The overhead wire is a viable option for powering detached garages for homes where underground wiring is problematic. We’ll show you how to run overhead electrical wire to a garage today, as well as the procedures you’ll need to take to power a shed or detached garage.

Needed Tools And Materials

  • Drill bit set
  • Screwdriver
  • Hacksaw
  • Duct seal
  • Electric tape
  • Fish tape
  • Electric wires
  • Two conduit strips
  • Switch
  • Pipe bender
  • Electric boxes
  • Spade
  • Pliers

Seek For Legal Permit

Any type of modification or new electrical connection in residence necessitates inspection and clearance from local government utility services and compliance with applicable codes. As a result, before you begin wiring your detached garage, you should check with the local office to see what codes and laws apply to overhead wiring.

Furthermore, many localities prohibit or have unique standards for overhead wiring. As a result, you’ll need to have your home inspected and obtain authorization to install overhead wiring.

1) Use Metal Conduit

Wiring inside rigid metal conduit costs more than burying underground feeder cable (UF), but it saves time. This is because the top edge of the RMC must be just six inches below the ground’s surface.

It may not seem like the extra six inches of trench depth is a huge concern. However, having rocky soil, hard clay, or many tree roots will add hours of backbreaking effort.

2) Clear The Surroundings Before Installing Wires

The overhead wires should be kept far from the house’s public spaces, such as the entryway, patio, and garden. Overhead conductors should be away from porches and windows in the open state.

Trees and electrical poles should be kept safe from overhead cables. Water sources, such as swimming pools, and spas, must be kept away from the overhead wires. According to utility standards, they should keep a safe distance horizontally and vertically.

3) Dig A Trench

To dig the trench, use a mattock. Because the head is narrow, there is less dirt to remove and less dirt to replace. With a spade, cut out strips of sod so you may properly patch the lawn afterward.

When planning the route from the home to the shed, various aspects are to consider. Begin by identifying a power source, which could be your main panel, a ceiling box, an outlet, or another electrical box.

It’s a good idea to drill the hole into the house before you start digging, just in case you run into a problem and need to move. Dig a trench from the home to the shed once you’ve determined the exit point. So, you don’t have to scrape the dirt out of the lawn later; pile it up on plastic tarps.

4) Run The Wires Through The Electric Boxes

The most challenging phase is running the conduit through the wall to an inside box. Then, one by one, thread the pipes together until you reach the other end, where you’ll cut and bend the final piece of conduit to fit, then join it to the LB using a compression connector.

After that, run a guy-wire to bolster the power cable because it can’t sustain its weight. To connect the guy wire, remember to set up additional supports. Because wire length varies with temperature, run the guy-wire with some slack.

5) Add A guy Wire

Install a guy-wire between two independent supports, such as your home’s and garage’s conduits. Because electrical cabling and wires can’t hold their weight, you’ll need to employ a guy-wire to provide some mechanical support.

Make sure the guy-wire is adequately insulated and sturdy enough to sustain the weight of the cabling. Allow for slack in the guy-wire, as it will shrink and expand depending on the weather outside. When it gets too cold, the wire will rip itself out if you’re not careful.

6) Use Fish Tape To Tie The Wires

Remove the fitting’s covers and secure the conduit with a piece of fish tape. Fill the conduit with fish tape and feed it through. After threading the wires through the fish tape, wrap them in electrical tape. To protect the hook from snagging, wrap it around the fish tape. Use stranded wire instead of solid wire.

Grasp the wires and pull them through the conduit. You’ll need two wires for one circuit, one white and one black, or more if you want to wire a three-way switch from the house or add extra circuits.

7) Install A Switch For To Turn On And Off The Power Supply

The wires require disconnecting the electricity as it enters the shed, such as a single-pole switch. Connect a switch to the cables inside the shed. Run cables from the switch to the receptacle, then to the rest of your shed’s outlets and lights.

That’s everything you need to know about running an electrical wire above ground outside. You’ll be able to run outside lighting and power tools with your new direct aerial cable to the garage.


You now know how to install overhead cabling in a detached shed or garage. Remember to verify with your local building codes to confirm that you have the authorization to run overhead cabling – the rules and restrictions vary by neighborhood.

Finally, remember to call professionals if you require assistance with the conduits. Finally, don’t run cables over water features, such as swimming pools, to save yourself from any risk and damage.
