| Jul 17, 2021 at 4:05 | comment | added | onlettinggo | Thank y'all for the input into this. The more I think about it the more I just want to replace the double 25 with a single 15 GFCI breaker to duplex 15 outlet and just run 2 extension cords to the shed and call it a day. That way I'll have 2 circuits, dedicate one to tool use and the other to accessory use. Won't be a big deal plugging and unplugging 2 cords. I already have 95% of the things I need and won't have to spend additional $. It will hold me over until I can pony up the thousands of dollars to run proper electric | |

| Jul 16, 2021 at 22:50 | comment | added | manassehkatz-Moving 2 Codidact | @MonkeyZeus That is a good cord, but really much more of a 1-to-3 expander, since it is only 2 feet long. I'd typically see that as "long extension cord into the yard, add this to allow multiple devices at the same time". Presumably the shed is more than 2' away from the house. | |
| Jul 16, 2021 at 22:28 | comment | added | NoSparksPlease | See NEC Table 400.5(A)(1) i.sstatic.net/AcCV2.png , it shows cord amperage. #14 cords are good for 18A, a #12 is good for 21A. So you could ask why they call a #14 a 15A cord? A very least is would require 20A plug cord end cdn.shopify.com/s/files/1/0166/0070/products/… then you couldn't plug it into a standard 15A receptacle. Also notice( nearly) all 20A receptacles accept 15A cords. This is considered reasonably safe or the NEC wouldn't allow it. Go with Ed Beal's answer. | |

| Jul 16, 2021 at 20:03 | comment | added | onlettinggo | @MonkeyZeus thank you! How would you handle the 20 amps once inside she's? I'm assuming just plugging in a regular ole power strip would bring up the same fire hazard issue because the power strip won't be rated at 20 | |
| Jul 16, 2021 at 20:01 | comment | added | MonkeyZeus | @onlettinggo I'm glad I could help you avoid a fire hazard =) | |
| Jul 16, 2021 at 19:58 | comment | added | onlettinggo | @MonkeyZeus I think you've settled it in my mind. I was planning to do two runs with 2 15 amp extension cords but I'm leaning toward getting another power inlet rated at 20 amp, 20 amp ext cord, 20 amp outlet, with 20 p breaker and be able to run everything off of one cord.... | |
| Jul 16, 2021 at 19:53 | comment | added | onlettinggo | @manassehkatz-Moving2Codidact clarifying, I will be plugging and unplugging the extension cord as i have no problem doing that. We hire a lawn mowing company and the last thing I want is to leave this cord strewn across the lawn when I'm not around lol | |
| Jul 16, 2021 at 19:52 | comment | added | MonkeyZeus | Like I said, "The dangers of electricity are all about amperage pulled over a given distance for a given amount of time." You'd probably be fine running the shop vac and miter saw at the same time for brief (15 second periods); I assume you're using the vacuum for dust collection. But if there is nothing stopping you from exceeding the rating of the cord then you have a fire hazard. The right answer is to use a 20 amp extension cord; not two fifteens because nothing is stopping you from abusing the undersized extension cord. | |
| Jul 16, 2021 at 19:50 | comment | added | manassehkatz-Moving 2 Codidact | What you really want is 2 circuits. That way you can have the lights & vac on one and the saw (or other tools) on the other. Which can be done with either 2 separate runs or what is called a MWBC - using two hots + neutral to get two x 15A or two x 20A (depending on the breaker). The catch is that using extension cord/inlet/etc. (in this case, it would be 2 extension cords, etc.) is OK temporarily but not as a permanent installation - and what you describe is, in reality, a permanent installation. | |
| Jul 16, 2021 at 19:49 | comment | added | onlettinggo | @MonkeyZeus very good point! Don't trust the human lol. Oh and I will be plugging and unplugging the extension cord and not leaving it plugged in 24/7 | |
| Jul 16, 2021 at 19:48 | comment | added | onlettinggo | @manassehkatz-Moving2Codidact ahhhh ok, that makes complete sense. Thank you. Really I'm trying to run a miter saw (15 amp) along with 1 led light, shop vac and possibly a fan at the same time. Right now I have a 15 amp outlet going through a 15 amp power inlet and I know that won't be enough. Soo, I'm thinking I could have a double cord setup with two inlets with one decorated to only the miter saw. I've been trying to think through this with what I have available. I suppose I could get a 20 amp inlet and a 20 amp extension cord to do with a 20 amp outlet and 20 amp breaker..... | |
| Jul 16, 2021 at 19:44 | comment | added | MonkeyZeus | In a nutshell, it sounds like your extension cord is a planned "permanary" extension of your electrical system so you need to size the breaker for the lowest common denominator; 15 amp extension cord. The dangers of electricity are all about amperage pulled over a given distance for a given amount of time. The 15 amp cord is fine if you NEVER pull more than 15 amps or 80% of 15 for 24/7. Your thought process is based on human trust, the 15 amp breaker is based on safety. | |
| Jul 16, 2021 at 19:42 | comment | added | manassehkatz-Moving 2 Codidact | That's exactly the problem. If you plug in a multi-outlet strip in the shed and overload it with 20A for a while (e.g., 12A heater plus some tools), the breaker will not trip because it is OK with 20A. And the wiring inside the wall will be fine. But the extension cord is likely to have a meltdown. | |
| Jul 16, 2021 at 19:36 | comment | added | onlettinggo | @MonkeyZeus can you explain the reasoning? I'm not trying to be combative, just still learning. My current thought pattern is still doing a 20 amp with a 20amp outlet would be able to supply the cord just fine and the problem would come if I were to try to draw more than 15 amp through the cord.... | |
| Jul 16, 2021 at 19:31 | comment | added | MonkeyZeus | I see. Then it's important for your breaker to be 15 amp since the extension cord is only rated for 15 amps. | |
| Jul 16, 2021 at 19:28 | comment | added | onlettinggo | @MonkeyZeus thank you, please see my comment below | |
| Jul 16, 2021 at 19:24 | comment | added | MonkeyZeus | Why not do a 20 amp outlet? Assuming the wire is 10 AWG you should have no issue using the screw on the side of the outlet. Don't you dare try to use the backstabs!! | |
