When I worked construction, I always assumed it was so we could plug 3 items into it at the same time. Or use the heaviest duty cord from the temporary pole to the worksite and then plug several smaller extension cords into that.Yes, the Female end is always the problem. You should use AWG 12 for 15amp but even if you have the biggest wire size, female end on most extension cords will fail if used for a long time at that current. If you look at 10AWG construction cords you will commonly see a tripple plug on the female end because the female end is the week spot.
