Looks like this is the same one at HD. $61 today.

I've also grabbed Made in US 12/3 cords at Costco for a decent price, and their 2 x 50' cords are $50 right now. This is a solid deal.

It's not just the gauge, but also the length that matters with voltage drop.

Yes, 12 gauge normally can do 20 amps, but not at this distance.

Why do extension cords use 12/3 when romex this would be 12/2? This extension cord only has 3 wires correct?

It's rated at 15a because of the plug, not the wire gauge.

Voltage drop at 100' is 4.76V vs 6.35V for 15 and 20 amp loads respectively.

Regardless, great deal on a 100' cord.

Don't know why the nomenclature is different, but yes- this has 3 wires.

Great deal. In stock for me.
Bought one last year for $45 so I don't need one, but if you need a 100ft cord that can power anything a normal house outlet can power, this is it. I use it on my 15amp snow blower without any issues.
