How to Add More Outlets to your Garage

Most garages only have one or two outlets at most. But let’s be serious now. Why would a builder only install one outlet ?. Simple, because he’s only doing what the minimum code requires.

We have a choice here. We could either open the walls up and start running wires and installing boxes. Or we could surface mount outlets with metal boxes and conduit. It’s way easier to surface mount. Hey, let’s face it, it’s a garage right. I don’t think anyone of us would like this inside our house.

Just remember, if the breaker was 15 amp, install 15 amp outlets. If it is a 20 amp breaker, use 20 amp outlets and the correct GFCI outlets.

How to Add more outlets in your garage.
Watch this video on YouTube.
Doing my best to bring you the best videos I know how.

Here is a list of items you’ll need.

  1. You’ll want something like this BOX

  2. How did you attach the box to the original outlet box? My holes don’t line up. Thanks in advance.

  3. Sorry for the delay. I was on vacation. You can use a drywall screw.

  4. Hi Dominick, thanks for the video. What kind of screws do you recommend for mounting the boxes to drywall or wood studs?

  5. Yes, you could but plastic is not cheap. However, you don’t always need to bend the conduit. In my video, I didn’t bend anything.

  6. Thanks for the list, it’s greatly appreciated, can you use pvc for electric instead of the metal conduit because I really don’t want to buy the pipe bender, thanks for all the information.

  7. Good day, first of all this is a great and informative video, my question is that you mentioned a shopping list posted somewhere and I just can’t find it anywhere. Can you post it or email it to me, it will greatly be appreciated.

  8. One GFCI is fine. And yes you could install a switch. wire mold is ok.

  9. Dom, great video. If I am turning one outlet into two on a covered lanai, do both outlets have to be GFCI or will the protection work all the way to the second? Also, can I put a switch in between the two outlets to control the new outlet?

    Lastly, is using wiremold metal raceways ok for a covered lanai? or would I need conduit? thanks!

  10. Your video is exactly what I am doing to my garage. Your video is informative and entertaining and very helpful. I am curious as to how you mounted the box to the original outlet. It looks like it is being held in place by one screw. Is there more to it?

  11. You are the best DIY expert out there! Ever since I got to watch the adding outlets in Garage, I’m looking for more in your channel/website! I love your humor!!

  12. Somehow I lost the receipt I had, sorry.

  13. Very helpful video, this is exactly what I am looking to do. Can I please get a list of items used on this project ? Thanks !

  14. Just add more outlets from the one you have in the shed. Watch my adding more outlets in a garage video.

  15. Thanks for your instructions. I have a question. My main power box is mounted on the outside of my mobile home approximately 25 feet from my work shed where I have only one outlet inside mounted which is ran from my main power box. . Can I run other outlets from that one inside or do I have to have a sub panel as well. Hope you understand what I’m asking. Thanks.

  16. Hi Jeff. Jeff for some reason or another I don’t have that list anymore. I’ll have to make a new one sometime.

  17. Hi Dominick,
    Great video on adding more outlets. I am just finishing a new workbench and need some power accessible and will likely do just as you described.

    You mentioned in the video a list of the parts you used, but I cant seem to find it. Do you still have that, or can you send me the link to where on your site that is listed.
    Thanks again.


  18. You always need the three wires. Yeah sure you can add one with USB ports anywhere. As far as moving that one outlet I would just use a cord being that you don’t own the house.

  19. 1 – Thank you. Your video is on point exactly what I was looking for.
    2 – You installed a duplex at the end of the line. Is wiring that the same as wiring a single?
    Why did you end up with 3 ground wires? Couldn’t you just the ground wire from one of the romex that you ran through the conduit? Would I have to use 3 as well?

    What if i wanted to use a singleoutlet with 2 USB ports?

    I want to move an outlet from behind my bed to an open area about 3-4 ft away. Can I use your method? Its an apartment so I can’t cut into the wall.

  20. Great Video! Can’t wait to get to work! Quick question. Due to some things I have already done to my garage, I’m thinking about running from my garage door opener outlet. I know code is that everything except ceiling outlets in a garage needs to be gfi. I don’t want to climb on a ladder every time the gfi trips… Would it work if I had my 1st outlet off of the ceiling outlet my gfi? Then run from that one to add the others? Would that fit code and work period? Sorry if this is confusing…

  21. Hello Dom,
    I’m really enjoying your videos. They are all right to the point. A question for you. I’m adding a 20 AMP circuit to my new garage. I want the power coming in from the new 20 AMP circuit 12/2 , that I ran from my breaker box to begin at a 3 way switch by the door for two over head lights. Can I run that 20 AMP power (always hot)off that 3 way switch to feed 2 quad duplex outlets over a new workbench and 3 single duplex outlets along the wall as well, from that 3 way switch? The other 3 way for the overhead lights will be on the other end by the roll up door.

  22. Well explained Dom,you know i love doing electrical works, Im sure i will learn a lot from you, thanks.
