      I am curious about why the 2nd receptacle (load) was wired split? Neutral was connected on the neutral side, but it wasn't directly opposite of the hot?
      Is there a benefit? Or does this fall under the belief it doesn't matter?

      Modifying any standard equipment is a code violation, right?

      Much respect. I'm always looking for easier, faster and safer (better) ways to things I've been doing for years. Well, today is my lucky day... I found a couple of variations in your technique, that I really like!
      Question:
      What's the difference between wisdom and being knowledgeable?
      Answer:
      Wisdom is the application of that knowledge!
      I'm planning on doing the wise thing and incorporate those little tricks into my program. Cheers

    I'm 71 years old and have worked in construction since I was 15. I have never had as much information shared with me at one time as I have in this video. I love the fact that the most "minute information" isn't overlooked. I learned as much in 18 minutes as it took me several years to learn. Well done indeed. You sir are amazing at your ability to instruct.

      @Anthony Crots there is no doubt that it may be used somewhere that is not up to code since 95% or so of homes are not up to current code and may not have been up to code at the time they were built. The point is that it won’t hurt to use the GFCI it is just likely overkill and may lead to nuisance tripping. If you are truly concerned about using the cord in a wet area (the primary place you use a GFCI) then you probably wouldn’t build it out of a metal box that will easily take in water. You are correct that the wire size would likely not affect whether or not the GFCI would function. I misspoke in my first comment and was thinking about an actual breaker. The size of the wiring is everything. If you are using large tools such as table saws and air compressors then using a small cord will limit the current flow and your tools will not operate at capacity.

    • Anthony Crots
      Anthony Crots 23 gün önce +1

      @Darian Bethune I'm not an electrician so I'm just trying to understand how it wouldn't be useful and how the size of the wires would matter in regards to a device that measures a Delta in current. It may be completely useless and I am ready to concede that. I don't think the box is being made under the assumption it's always being used where something was built correctly and up to code.

    • Darian Bethune
      Darian Bethune 23 gün önce +1

      @Anthony Crots If the box is properly bonded back to the UFER or ground rod then the GFCI plug will do nothing for you unless you somehow drop your saw into a puddle of water or something like that. But as I said your garage or shop should already be GFCI protected so why spend the extra for the GFCI plug?

    • Anthony Crots
      Anthony Crots 23 gün önce

      @Darian Bethune Is a GFCI meant for overload protection? I thought it was meant to monitor for a difference in current.

      @Vernon Gilmore correct! OSHA doesn't like to see "fixtures" rigged onto extension cords. Ext. Cords are the most identified violations with all NOV's and "spot" inspections.

      Well since you are a "why" person.

      You should ask yourself WHY? Is this dude putting a grounding wire on each of the devices if the box is grounded and the yokes are grounded to the box .

      The reason we use metal boxes, is because they are our grounding.
      All you need is one wire to the box, everything else is grounded.

      I’m in the same boat man. I need to be broken down Barney style to understand what and why things are done this/that way and you don’t get that most of the time while OTJ because people act like you’re troubling them by asking them questions. I was green 10-11 months ago and while I have a better understanding it felt like a lot of picking and prodding to get to this point. Glad I’m not the only one, because it tends to feel like that at tjmes

    I've built several cords almost exactly like this and I've found that bolting a 2 hole conduit clamp to the box so you can hang the box from a nail, screw, etc is tremendously helpful.
    I always put the conduit clamp on the side of the box opposite where the cord goes in so that way they always hang cord down.

    Also something I do for safety on these, to keep from having a loose metal fastener inside the box, I bolt the clamp to the box using nylon locking nuts WITH red loctite thread lock to ensure the nuts never come unthreaded. It's a piece of mind thing for me.

    Nice, that strain relief is an amazing item! I used to make my own custom extension cords all the time. I had need for a lot of different 110 & 220 male plug configurations, so would also make short adapter cords. Also made a dual use 220 cord with a 220 & 110 outlet box on the end. Run the big compressor & have an outlet for the 110 power drill! Had an employee one time try to make one, he stripped the wires bare for a full 12", wired it up and was ready to plug it in! "Yee-ow"...

    Thanks for an awesome video! I learned a few things and I really appreciate all the explanations. I would suggest 2 tweaks...I like to use heat shrink tube on projects where wire needs to have a little extra strength. I've even put it on phone charger cords to help make them last longer. About 6 inches of shrink tube before the box (applied and shrunk before ordering the McMaster) could give it more protection. I'd also consider mounting the box to a scrap 1" X 4" piece of wood. Drill a hole in the wood so that it can be hung on a nail. Good choice on the non-GFCI outlet - made in the USA! Subscribed today.

    Back in the 70s, my dad made these for job sites. He had several heavy duty extension cords with either 2 outlets or 4 at the ends. To make things even cooler he had these short corded ones. Same 4 outlets on the end but the cord was only about 12 inches long. This was much easier to unplug and then coil the extension cord. Great video. Great tutorial.

    Great idea! Really impressive and detailed walk through!

    If I ever to do this, I would use the industrial raised cover plate with two decora style device cutouts, instead of duplex one, one for gfci receptacle with a pilot light indicator for visible status, and one decora receptacle with two usb ports.
    Also, using insulated, stranded ground may be a debatable improvement.
    Last thing to note, I like to wrap electrical tape around terminal screws of devices just for two main reasons.
    One, when devices are side by side, neutral terminals of one face hot terminals of the other, regardless of a box being plastic.
    Two, potentially working on on a box with energized circuit, making it safer to remove the devices.

Wish I knew that years ago... been doing it the ape way for way too long. And little riddles on outlet tabs were very cool!! A good reminder to pay close attention to the details. Areas for improvement; some loctite on strain relief threads (at box junction) might be advised. And you used a digital caliper not a dial... :-) Thanks again!

    I've been making cords and temporary power taps like this for a long time. When I worked working as an electrician (many, many years ago) one of my coworkers turned me on to doing this. The only thing I do different is I love using "hospital grade" replacement plugs. They are a way better quality and a lot have built in indicator lights showing proper ground and correct polarity. I might spend a little more money for the better plugs, heavier wire, and exterior weather proof boxes but I trust my extension cords with my life and I know they will last a long time. 👍👍

      ​@Larry Coates Yes, but the problem is you have to use a 20 amp plug which will not go into a 15 amp receptacle otherwise you're just throwing money away on 20 amp receptacles. Or if you put a 15 amp plug on with 20 amp receptacles you run the risk of someone plugging in a device or tool rated for 20 amps. You'll either keep tripping the breaker, over heat the wire going to the breaker, or ruin whatever you have plugged in depending on amp draw. Or you can do what he just did and use 12 wire to make a 15 amp extension cord and call it a day.

    • Larry Coates
      Larry Coates Aylar önce +1

      @Luis Hernandez He stated that the cord is 12 guage and is therefore rated to 20 Amperes thus using 20 Amp GFCI & receptacle is appropriate. If plugged into a 15 Amp circuit, the panel breaker will protect the building wiring. If the extension is plugged into a 20 Amp circuit all 20 Amps would be available and protected by the panel breaker and for Ground fault conditions.

If YOU want to wear a helmet, or YOU want to force YOUR kids to wear helmets, fine, do that. It's not for government, that's my point. Sometimes you have to be the mean parent but it's easier for you to have the government do it rather than parenting yourself.

    I went a different way though, with 150ft of 12/3 (found at a local metal recycle yard), with 3 single gang utility boxes & duplex utility covers, put together in series with four (two between each box, for stability and cable wiring space) 1/2" compression connectors (not a compression coupler, although the nipple is similar for both, but the connector is just cheaper). I just used a 1/2" locknut on each side.

    This way I can add another box if needed (haven't seen the need for it in over 35+/- years, so far, but glad I went with the 6 plugs, less time spent having to unplug and plug-in equipment that does get the most usage), but for a chop saw, portable table, portable shop vacuum, and a couple of battery chargers, it's just fine.

    I have one plug left for what ever I need to use, drill, hand held planer, jig saw, reciprocal saw, palm sander, belt sander, hand held circular saw, etc, as well as another smaller extension cord for the afore mentioned non-battery hand held power tools. Plus it's just me, so I can only use one piece of equipment at a time anyway.

    On a side note, I could go all battery operated tools, but why, when the cabled versions I have work just fine and are only used as needed. If I was a contractor using them each day, that might be a different story. I do have a battery operated impact capable drill and impact driver, but those are still 18v ni-cads that work just fine. I am in the process of having the battery packs rebuilt right now, as it's cheaper than buying new tools. Most battery only stores do this kind of work.

    Back to the build, I have not seen the need to use anything but a LOOMEX threaded lock nut style connector to hold the cable, as I don't use it as a rodeo rope, if it does come loose, I just tighten it, but I used thread lock, so it hasn't really been an issue.

    I have yet to see the need to use a USB style receptacle, as I don't want my phone laying on (or near) the ground, in the dirt, grass and or what ever else construction trash is around. I leave the phone where it won't get damaged. Plus with using hearing protection I wouldn't hear the phone ring, or be able to carry on a conversation. I just check my phone when I take a break, get more work done that way.

    At the time I built it, I went with a simple 125v 15amp Leviton duplex receptacles, this year I just replaced them with their tamper resistant versions, but still used the side lugs, the back side inserts make it harder to deal with the limited depth of the box itself. They were wired accordingly with braided wire taken from cut-offs from the cord itself. Plus using the lugs is better for repairs and or additions.

    When I first built them I also drilled an "x" sized hole (cannot recall the size) in each corner of the cover to put in a neon bulb, which just this year I replaced with a green LED (which one can find anywhere). I have only had to replace the Leviton 125v 15amp python style male plug once (when it broke in -45+ degree celsius weather), as the 12/3 fits just tight enough not to have to worry about the wire coming out of the plug itself. I should replace it one day with their LED version. Model # 515PV-R50, because why not.

    I haven't really had to worry with using it in the rain, as I wouldn't, and we have GFCI by code for outdoor wall plugs anyway, as I am sure it is just about all over. I would clean it with compressed air each day after use, as I am cleaning the tools anyway.

    It has served me well these past 35+/- years, only having just recently done an upgrade, not really a repair.

    Like with anything, if one treats it like it costs money, it'll last that much longer.

    Peace. 😎

    One thing I always do after building an extension cord is plug in a tester before I plug in anything else. While I know I’ve been careful, it confirms the fact that the polarity is correct, and that the cord is safe to use.

    I keep the ears as washers. I'd tork them a little and use'm with self tapers or whenever I needed a little space or compression. I've made a ton of 4-square boxes but started using spray rubber in and outside the boxes when I'm especially working outside off a dedicated circuit. If you can locate a GFI with a pilot switch combination or attach two 4 Squares you could put on 3 receptacles plus the lit switch. It's handy when lights are not bright on the job finding power or when I'm working outside at night.

    I have made these with an addition. I mounted the metal box on a 10"-12"square of plywood so that when I pull my tool cord out I can use just one hand and step on the box. Without it I either have to step on the box, which may have 3 other cords plugged in, or hold the box down with one hand and pull out the cord with another. It also keeps the box facing up no matter how I pull the cord around. I also spray painted it NASA orange to let it be easily seen on a busy jobsite.

    Doing these I've also added a piece of flat stock with holes across the back exterior. This allowed me to screw it temporarily to the floor or wall. If some other person on the job somehow dragged my cord moving something or even tripping on it, this would prevent my plugged in tools from going for a ride, especially a saw or drill that was in use.

      @Rexx Seven Wrong box for multiple reasons, multi outlets serve no purpose except to overload it, jumpers too short, wrong jacket strip technique.
      With all my training and experience it's easy to spot these people who think they know how to work with electrical but don't, based on their language and attitudes. They think because they managed to replace a switch without burning down the house once or read a basic how-to that they know everything, but there is so much more to it of which the average layman is unaware.
      Most experienced electricians I've worked with knew how to properly do the work and adhere to codes but still had no idea how electricity actually works.

      Be sure to check the wires with an amp meter for resistance.
      Old extension cords are dangerous for the simple fact that the same characteristics that make them flexible, cause them to lose ampacity over time.

      @Scott Satterthwaite Exactly right. 99% of the time you have to reset a GFCI is because it tripped due to overload, not ground fault. Maybe not 99%, but probably 90% minimum.

      @Jim Michaels I get the idea. It just isn't necessary. In the first place, the voltage loss difference between 10 awg and 12 awg isn't enough to worry about. Second, as someone else pointed out, we don't use all four outlets at the same time (usually). As for a GFCI; You are incorrect. Although a GFCI is not intended to be an overload device like a breaker. Two main conditions will cause a GFCI to pop: 1. current differential through the load of .005 A. (ground fault) 2. Current greater than the load limit of the GFCI. So no, you cannot run 50 A through a 15 A GFCI without it popping.

    • Jim Michaels
      Jim Michaels Aylar önce +1

      @Scott Satterthwaite The upgrade to 10 AWG is to reduce loss in a long cord, not to increase the capacity. GFCI Outlets do NOT provide overload protection! you could put a 15 amp GFCI on a 50 amp circuit and load it to 50 amps and it would just get very hot but would not trip from the overload. Exactly the same as a 15 amp standard outlet, it is RATED for use at a maximum of 15 amps but does not contain any mechanism to enforce that rating, that is the job of the circuit breaker feeding it.

      Back in the early 70's I was working as a carpenter at a Mall addition. I took some scraps to the dumpster and when I looked, there was a BIG extension cord in it. I am no fool so started pulling it out. Two hundred-foot heavy-duty cord with the male plug and the other end cut off. I took it home and made a box just like yours except that there is no strain relief. Used it later on in my jobs and it now provides power to my wife's SheShed.

    I've made a bunch of these with molded NEMA enclosures and weatherproof covers. I recommend two upgrades: (1) Use two GFCIs wired in parallel, so if you trip one, it doesn't knock out the other at the same time. The power cord enters the enclosure, you split it (by adding wires), then feed each GFCI. (2) Use nylon insert lock nuts, which is helpful if the assembly is exposed to vibration. When I used to work as an engineer designing intrinsically safe equipment for use in explosive environments, we would fill the enclosures with a special type of fine sand and compact it on a vibratory table, hence the experience using the nylon lock nuts. No plugs in those environments though. It all had to be hard wired because arcs make wonderful ignition sources.

    Someone asked "what happens if you plug a GFCI extension cord into another GFCI and there is a ground fault?" Answer: One of them is going to (hopefully) trip. Which one? It depends, but probably the one that makes you walk the longest distance to reset it.

      @Darryl Kinslow it would be better to make two extension cords and plug them in two different circuits. I don't really see a need to even use one GFI on an extension cord unless the outdoor outlet is not protected by a GFI.

    • Darryl Kinslow
      Darryl Kinslow Aylar önce

      If you trip one, you want both to trip, you actually want anything connected on the same outlets from the wall to trip, otherwise you risk damaging the electronics that suddenly get a surge of electricity because the one side isn't being fed anything anymore. Never should only part of a set of outlets not trip when there is a power issue. Hence surge protectors connect to all of the outlets on the power bar, not just half of them. If the power trips on one side, there is going to be a difference in grounding on the other side too all of a sudden, and the other side should trip too because it should detect a fault when the other one goes out. If there's a ground fault, why would you only want half of the stuff connected to be disconnected when all of it should be?

    • Ron B
      Ron B Aylar önce

      I would skip the GFI. I never would use them outdoors the outdoor outlets are already GFI. But I would use my sealed extension cords outside. Now we have ACFI breakers to deal with. All these safety devices and still people get shocked or start electrical fires. I remember the days there were no grounded outlets. The grounds were the metal boxes when EMT was used..Fuses were the circuit killers

      When will it ever end? Use cordless tools then you have a new can of worms to deal with.

    That drawn box has knockouts that can be hit as the box is banged around on the jobsite and knocked into the connections on the devices causing a short that is not protected by your GFCI. I use a metal weatherproof box with screw in fittings to avoid this problem and keep the OSHA inspectors at bay. Costs a little more, but it is durable and much safer as the crew bangs it around.

      I'm an electrician and I have done this life hack many times. However, I was told by an electrical inspector that it's better to use two regular receptacles rather than that GFCI receptacle. First of all, that particular GFCI receptacle is not UL listed for rough service... (being dragged around on the end of a cord). Second, on a construction site and all new homes, anywhere you will grab power for that cord, including most generators, will most likely have GFCI protection. Most people don't understand that you don't want to have redundant GFCI protection. In other words, it's redundant to plug a GFI cord into a circuit that is already protected by a GFCI. It's not necessary and occasionally they can cause one or the other to malfunction. I do love the video and I thought it was clear and concise.

I have a couple wrinkles, one is to reverse the direction of the recepticles, just have found it handy. Second is mount the box on a piece of plywood or plank keeping it off the ground as protection as well as a bit of extra length having a hole one end and u-clip on the wire end. Can hang it and fix a lanyard for tie off coiled cord as when hung for storage.

I have an old, heavy gauged one mounted to the side of a small wooden spool with about 30 ft of cord wrapped around it. Plug it in, roll it out and lay it on its side. Outlet is up off the ground and you have a little table to boot. Two things I would have done differently from your video though: one, I would add lock washers against the outlet mounting nuts and two, I would have wrung it out with an ohm meter before plugging it in.

    I remember years ago walking through construction sites and seeing extension cords made of Romex. Sometimes they didn't even have proper cord ends attached, instead they would use a wall outlet in a blue wall box for the female side and the male side was just the wires stripped and pushed into the holes of the outlet. I think it's hilarious that some people think the extension cord built in this video is a safety hazard.
