Most garages don’t come with a 220v or 240v outlet. But modern handy tools and garage equipment need 220 volts to operate and that’s why many people hire electricians to redo the wiring on their garage.

Whether you are wiring your new garage or just redoing the electrical wiring, hiring a professional is always advised.

But in case you are planning to DIY it, you might come across questions like how to run a 220 line to my garage, where I should bring the line from, what wire I should use, or how do I install the outlets.

To help you run the line and outlet, here’s a complete guide on installing a 220v outlet in your garage.

How To Run Wire & Instal A New 220v Outlet in the garage

Step 1 Choose the source which you’re going to draw the line from.

The basement is the best and easiest place to draw the line.

If you don’t have a basement or have a detached garage, you might need to drill additional holes into the walls or do some digging under the ground to link the garage outlet point and the breaker box panel.

Step 2Pick a Location to put the outlet.

You need to choose an easy access point from all corners of the garage, ideally, in the middle of the back wall or on the ceiling. Wall is the safer option between the two.

Step 3Drill a hole into the separating wall or floor.

Make sure to decide on the two endpoints before you start drilling. Additionally, be sure to remove any insulation if there is any.

Step 4Measure the distance from the breaker box to the hole where you are going to install the outlet.

This is how much wire you are going to need. But make sure to buy a foot or two extra.

Step 5Make sure the breaker box panel has space for a new circuit breaker.

If it doesn’t, you need to call for an actual electrician to swap the breaker box and redo the wiring on the panel. This is an intricate process and a professional electrician’s help is advised.

Step 6 – Purchase a circuit breaker, 220-240v outlet, and wire.

For the breaker, wire, and 220v outlet, Home Depot is a good option. You can get these from local hardware stores. For the wire, if you don’t know what type of wire to buy, ask someone in the store for help.

The same goes for the outlet and circuit breaker. The outlet will depend on what equipment you’ll be plugging in and its prongs on the plug. For the breaker, a 30 amp 2-Pole circuit breaker should be enough for most people.

Step 7 Run the wire through the hole.

Now take the wire to the breaker box panel using existing holes on the basement ceiling or wall. If there are no existing holes, drill some new ones carefully.

Step 8 Use wire staples every couple of feet to make sure they don’t move.

Step 9 – Install the double pole circuit breaker on the breaker box panel.

See if the breaker box has an opening in the bottom or top for the wire to go. If not, make a place to insert the wire through the side knockout.

Step 10 It’s time to put the wires in, so strip the end.

If you don’t know where the hot and ground wire goes, see a 220v wiring diagram online. If one of the wires inside the wire jacket is white, make sure to put black electrical tape on the hot white wire so that others can know it is not a neutral but an actual hot wire.

Otherwise, people might think of it as a neutral wire as white wires are neutrals on 110-120v. Don’t flip the breaker on once you are done with the wiring because you’ll have to handle the wires on the other end in the garage.

Step 11 install the outlet.

Now that you are done with the breaker panel and everything inside the basement or the power source, move on to the garage to install the outlet. If you are not sure about the process, look for instructions on how to install a 240v outlet on the outlet packaging box.

A quick note, 220v, and 240v are basically the same. More on that in our FAQ section. In most cases, simple wall installation with screws would be enough.

Step 12 – After you’ve screwed down the inside of the outlet, put the wires in.

Make sure to install the wires before you install the outlet cover. To do so, strip the ends of the wire that’ll go in the outlet and put the wires in accordingly. Cover the outlet once you are done.

Step 13 – Flip the breaker on and test if everything is working or not.

If you’ve wired everything correctly, it should work fine. If not, open the outlet cover and make sure everything was wired correctly. Do the same for the dual pole circuit breaker you installed.
