From what i can tell with the National Electrical Code the smallest wire listed is 18 AWG that is listed at 7 amps and 5.6 for continuous loads which is running for more then 3 hours at a time so i would rate a 20 AWG at about 5 amps MAX and 2.5 for continuous but good luck with that
depends on the wire gauge and strand type sold strand 12 AWG wire is 50.57 feet per pound. most extension cords however are not solid strand, they are multistrand line which allows for flexibility and breakage. standard size is 28 AWG, 2067 feet per pound. 7 strand 12-3 line gives you 1050 feet of 28 AWG or ~$2 worth of copper if its clean and bare, less if it still in its insulator or if the insulator is burned off.
120 15 amp service ? 210 7 amp service ?
Wire maker Pro Power rates their 7/0.1 at just 250mA when in a cable of 9, with screen around.
It's going to take a whopper of a wire to run a 20 amps 650 feet. I'd feel more comfortable if a journeyman electrician would come by to access my answer. But, my calculations show it would take 4 AWG wire to do it. If you want you could run two 7 AWG wires in parallel.
7 strands of 29 gauge (AWG) wire
The description you show seems to match the description for 16AWG wire made up of 259 strands of 40AWG, Rope construction with bunch stranded groups. Similar to concentric for the groups of strands. The wire is made up of 7 Bunches of 37 strands of 40AWG strands to make a 16AWG wire. The description should be 16AWG(259/40) construction is 7x37/40. The SWG more than likely stands for Standard Wire Gauge. This construction is a high strand count which would make it flexible. You can learn more about stranding and view a wire gauge chart on the link below.

there are seven (7) strands
No, it must be on a dedicated circuit of it's own. It must be on AWG 12/2 wire with 20 amp breaker. It also must be protected with a GFCI outlet.
A No. 18 AWG wire can handle up to 7 amps safely. Therefore, a 7-amp fuse should be used to protect the circuit when using a No. 18 AWG extension cord with only two conductors carrying current.
There is no defined AWG for 350 MCM. The American Wire Gauge stops at 0000 (4/0), and 350 MCM is bigger than this. An approximate conversion would be 6/0, if there were such a thing. Extrapolating out from 4/0, 6/0 is 334.8 MCM, and 7/0 is 422.2 MCM. These wire sizes don't exist of course, and don't exactly match 350 MCM anyway.
33% of 7= 33% * 7= 0.33 * 7= 2.31
