well. I now have dedicated circuits, two of them, one for my office and one for my family room where the larger production related stuff is set up. In the family room I have extension cords that are intended for studio professional use, worse case I could take one of them with me. Given amazon Canada has now rigged the site so one cannot refuse prime if using allot of adaptive technology I am likely going to need a store visit regardless..and the tp-links is now $26 laughs. If I get an apc serge protector with six feet, and a six or even 8 foot extension hopefully I will be fine. the problem with UPS units is, unless they talk, I cannot monitor activity at all.

14 is apparently not feet. to what does the /3 refer?
14 is the gauge (the diameter of each wire). The gauge number goes lower as the diameter increases. In house wiring the gauges usually used are:
14 for common 15 amp outlets. 12 for less common 20 amp outlets, normally found in kitchens. 10 for 30 amp electric clothes dryer outlets. 8 for 40 amp electric stove outlets. 6 for 50 amp electric stove outlets (not common) or electric vehicle charging outlets in the garage.
The above is great in theory but as soon as you start adding some length to those cables you better start using your wire size calculator. For a 100' cord off of a 15A plug you had better use larger than 14 ga if you want to limit your voltage drop to 1% the recommended wire size is 4 ga. Your chart says that should handle more than 50 A but your chart also does NOT include anything for length of run which becomes the more important the closer to the amperage rating of the circuit the load becomes. Ignore to your own cost and peril.
/3 is the number of wires in the cord:
A "hot" wire (the dangerous one if you were to touch it). A "neutral" wire that returns the current. It will be wired to "ground" at the electrical panel. A "ground" wire provided for a safe return path in case of an electrical fault.
/2 designates your standard 2 prong cord, which has a hot and neutral but no ground.
