To prevent cords from being stolen, put some tape around some sections of the cord. Thick enough to look like a repair.

People have left my "repaired" cords alone. Even found one sitting in a parking lot after it fell off my truck.

I grew up in a town with a Southwire factory. It's most definitely made in America! It's a family owned company as well.

You also need to factor in resistance over distance.

The longer the cord, the lower the peak.

For the longest time, I've been wondering: What's the purpose of using 12 awg cable if the rated limit is 15 amps for these extension cables?
Normally, 14 awg wire is capable of 15 amps and 12 awg is capable of 20 amps.
It looks like the reason is continuous use vs peak:
12 AWG copper wire is suitable for a 20-amp circuit, and it's a common practice in residential wiring. However, for continuous loads exceeding 3 hours, it's recommended to limit the load to 80% of the breaker rating (16 amps). - Google AI
Not an accurate comparison because residential wiring has a solid copper conductor for each leg (hot-neutral-ground), while extension cords use stranded conductors to make the cord flexible, but stranded wire has a lower capacity than solid wire of the same gauge.

Picked up a 2 pk of 50 ' 12/3 cord from Costco yesterday instead for $59.99. I'm sure it'll go on sale sooner or later for less, I'll price adjust if it is within 30 days.

Quote from CrimsonClass2402 :
That doesn't seem correct. Somebody tested the draw on the Partybox 710 from the wall @346 watts with everything on (the 710 is rated 800 watts from the manufacturer).

The Partybox Ultimate is a MUCH larger speaker and rated at 1100 watts. It's definitely going to draw more power than the 710.
If the 710 draws 346 watts, that is basically 3amps (346/120volts). If we err on the side of caution and assume the Ultimate draws twice as much power, that is still only 6amps. So if you have two Ultimates, that would only be 12amps total, which is well within this cords rating.

Came here to chime in exactly what killerrabit1961 said. He's 100% correct. Residential wiring is solid copper conductors, not stranded copper wiring. Solid conductors are able to carry more current comparitively versus same gauge counterpart stranded conductors in flexible extension cords. Your amperage figures are for solid copper wire residential runs, not stranded conductors at 100' distance.
Google AI is negligent in omitting the most important aspects of the wiring/amperage info.... stranded vs solid and the distance of the run.
Google AI also omits that the main reason for their stated 80% figure is because of max amp load on the breaker, far more so than the wire.

Google and Google AI (yet another 'tool' in the agenda of dumbing down the population). It gets ppl to just blindly believe whatever it pumps out instead of having ppl receive the 'big picture' (full & accurate info).
For the permanently misguided Google lovers, I'm sure you'll be downvoting, which also proves the agenda a success and true. 😁

As for the other poster who says he prefers buying multiple shorter length cords (say,, four 25' cords) versus buying a 100' cord and apparently doesn't see the drawbacks in using multiples, each shorter cords plug-in connection is the drawback. It inserts a point of potential mid-high resistance in the current which is not there in the continuous cord. The most common example of this resistance is when the plug burns & melts on higher amperage devices like portable space heaters, and that's just from the wall receptacle to plug connection. The 'friction' connection between any plug's blades and any receptacle's blades can sometimes/often be a point of significant increase in current resistance, which doesn't exist in a continuous conductor/wire and it's a weak link that need not exist.

What you really want if cold weather use is expected, is the US Wire 99050 12/3 50-Foot SJEOW TPE cords, unreal flexibility. SJEOW is elastopolymer jacket, weather rated and oil resistant. Much much more flexible than the SJTW of this cord, which is weather rated but has a much less flexible plastic jacket that is more durable.
agree, in cold weather sjtw is unmanageable if you want to frequently coil and uncoil them. SJEOW or SJOOW are better

I've been getting these SJTW 100' and 50' lighted-end 12gauge cords at Menards lately for 100' $45 and 50' $25 less 11% instore rebate: https://www.menards.com/main/elec...c-6410.htm These have a 1 year warranty.

I also get these all rubber SJOOW cords but they are more than double the price: https://www.menards.com/main/elec...c-6410.htm. I've got 1x100', 1x50' and 1x25'. I use these in cord reels as they are more manageable than the SJTW's

Great Project Farm review of extension cords and things to think about: https://www.youtube.com/watch?v=-j6sC_8Z4_w
for a few dollars more consider the PF TOP RATED: https://www.amazon.com/US-Wire-Ca...ast_sto_dp

Here's a great article, in plain English, on how to choose an extension cord. In short:
Settle for the 14 Gauge Or 12 choice of extension cordGauge - What you Must Know






Now that you have a general idea of what to expect or look out for when choosing extension cords, you need to decide which of the most popular gauges would work in different situations. The 14 and 12 gauge extension cords are among the most popular used types of cords. While there are different gauges, including the 16 and 10 gages, 12 and 14 are the most common. However, they carry different power amounts depending on the length of the cord in question. For instance, for a length of 25 - 50 feet, a 14 gauge cord will be great for 14-15 Amps, whereas the 12 gauge will work for 16-20 Amps.

For 100 feet, the 14 gauge cord works for 11-13 Amps, while the 12 gauge cord is best suited for 14-15 amps. If your cord is 150 feet long, the 14 gauge is best suited for 1-7 Amps, whereas the 12 gauge will support 8-10 Amps. This shows that the extension cord's length also plays a part in the power it helps safely.

Whenever you purchase an extension cord, make sure to understand the load it carries depending on the length of the cord. This will help you avoid overloading the extension cord and causing any harm to your appliances or yourself. The last thing anyone needs is to generate an electrical fault that can be more dangerous than good.

Quote from Souka :
People in reviews claim it's stranded copper... but odd nowhere on product page it's listed.

Also, is it "Made in America"?
Notice the packaging and cord say:
"We've got it
MADE IN AMERICA tm"
This is a trademark slogan... I'm willing to bet it's NOT made in America.
Deceptive how the "made in america" is bold also....

Also, the proper labeling is "Made in USA", so this is not that... so likely made in elsewhere (China?)

According to the Federal Trade Commission, "Made in USA" means that "all or virtually all" the product has been made in America. That is, all significant parts, processing and labor that go into the product must be of U.S. origin

I'm sure it's a fine 12/3 cord, just don't expect too much.

Quote from MacBroeden :
Someone with more knowledge should weigh in, but I remember being told chaining cords together is not a good idea.

My understanding, for example, was that a 25' cord was rated to be used by itself only... and that same 25' section is not designed or intended to be part of a longer length and could potentially be bad as it wasn't made to be carrying a current at that length.

But like I said, someone with more knowledge should probably say for sure...?
It seems diameter goes with inverse of gauge. That means a gauge 6 is twice thicker as gauge 12 and the available area for current 4 times higher. That also means you can daisy-chain 4 gauge 6 25' cords for something that a 12 gauge 25' cord is designed for.

But I would not recommend this calculation as mistakes could be made. One good rule is that if the cord is even slightly warm to the touch you are overloading it.

Would something like this be enough to use with a JBL Partybox Ultimate powered speaker? According to JBL, the speaker is 1100 watts.
Yes, this extension cord would work fine. It says it supports up to 15 amps, 125 volts, and 1875 watts.

I prefer shorter lengths i can chain together. Easier to deal with and coil, especially since most of the time you don't need a 100 ft length.
This adds all the resistance back in.

I have an old swing set that I need to power wash about 100 feet from an outlet in my yard. My current extension cord does not power the power washer so I'm hoping g this one will since it's a 12guage?
