Prime Wire & Cable Contractor Tough Outdoor Extension Cord, 25ft., 12/3 Gauge, 15 Amps, Yellow, Model# EC511825

These 25' cords made of 12/3 wire can be plugged together to service inside home from generator outside.Its nice to use just enough cord to reach what I'm powering. Also I straighten the cords by removing them from packaging, smoothing out the kinks, and stretching them across my garage trusses with bungees on each end. Now when I bring cords into house they lay flat on floor, minimizing trip hazard!

I use this cord to connect my Reliance EasyTran furnace transfer box to a 4400 watt generator outside. Since I handle the transfer separately from the other circuits, it's nice to have a separate cord for that purpose. This is a very heavy duty cord, probably in excess of what I need. It's a 15-amp breaker inside the transfer switch, so it's well within the rating for the cord. The one I got had lighted connections, as well. I'm very satisfied, this thing is industrial tough. In a heavy storm, with the generators going, a 14/3 cord just isn't going to do it. Spend a couple more dollars, and buy this 10/3 unit.
