If you use SS cord you don't need that large a wire.
SS? I'm talking a 15 amp saw on a 100 foot extension cord.
What are the specs for "super service"?
Didn't really want to turn my preference into yet another argument. I have a long SS cord I use for things like a saw. Don't remember the specs. I've sure someone will now make me look up the specs...
I just searched for "super service cords" and got nowhere, apparently the technology has changed and I'm not sure what the rolls of yellow or black cords with two or three wires are called these days. Didn't see any amperage ratings on Grainger's website for the various choices available today. If anybody's really interested you might try Grainger's site. The terminology is not what it used to be.
Let me explain. When I was working as an electrician, we had access to rolls of yellow or black SS cord. They came in several sizes based on the AWG of the internal wires. The amperage ratings for the cords was higher than what you'd expect, for instance a yellow roll with 14AWG internal wires was rated higher than 15 amps. A roll with 12AWG internal wires was rated above the normal 20 amps. The insulation of the cords allowed for the higher ratings. I managed to acquire a roll of yellow and one of black before I put down the tools and have slowly used them at home. I ran out of the yellow a few years ago. The black cord is used for oily environments and can be used as underground wiring. That's a PITA to work with and I still have some. I'll look later and see if the cords have the rating imprinted on the outer insulation.
I looked before I asked and it appeared to be a marketing ploy. "Super Service" could be the 12/3 cord that inkahauts wanted for his saw. I saw one reference on a 14/3 cord. The closest definition I could guess was "super flexible service cable" ... but I didn't want to guess. (It isn't my ship to dock.)
I did check the black cord, all it says is it's Type SJ, so that wasn't "super service" cord either. I don't know where else to look. I do have an old Electrician's Handbook, the ratings might be in there, if I can find the book. I'll look later.
I would just measure the wire to estimate max current, it would be hard task to get get data about an insulation (max temp and max voltage) though ...
I just haven't heard the term ss like that before off the top of my head. Didn't know if that meant something specific.
Sounds like industrial power cord. I think I've seen it just never called it ss before.
I'm a believer in go bigger so everything gets to work easier and have less stress. ( why work at the upper edge of its abilities vs 70%)
Granted I'm sure everything can handle more than it's rated for anyway.
I've always felt using 12 over 14 is better for several reasons, heat being one of them. This extra insulation jacket is an interesting twist. I'm guessing it's a rating as you say for the cable. I'll try and remember to look at the ratings for one older giant cable I have and see what it says.
I just spent some time with my Electrician's Handbook, it is easier to read than the code books but I can't find SS cords in it. And I'm done looking, I'm sorry I'm mentioned SS cord.
Oh don't be. I was just curios what it was. Never heard of it that way.
I don't like to write about things I can't back up.
Rich I believe you on stuff like this for sure. I've just never heard of it. I am sure that's true with things from all of us!

Try this ALL NEW HD HIGH LOSSLESS Extension cord! Gold plated contacts! Cleanes line interference! BETTER HD SIGNAL! LOL Sorry I had to do that
I'm using 12 GA SJ for my 1.5 HP pool pump (240V , load is usually about 5.5-6 amps) .
I'm also using it in my backup poolpump (3/4 HP) - 120V max load 11amps.
