I use this cable to connect the Transfer Switch (in the shop in the basement) to the receptacle in the basement family room. I had measured the distance and it appeared that it needed the cable to be 50 feet long, so I ordered this cable, and it is perfect with about three feet to spare. I imagine the cable is exactly 50 feet. The male and female connectors are high quality, and the cable is as flexible as it can be expected for a 10/4 cable. It is heavy.
