I needed this to get out of the house onto the covered patio. I used to use straight buried outdoor cable for wiring this patio, but this cable is very difficult to work with and the connectors become quite brittle due to the stiffness of the sheath. I'm sure it will be needed for direct burial, but for attachment to the patio roof like I needed I simply used this internal cable. I had to cut a connector to run the cord through a hole in the wall and found that changing the connector on these wires was very easy and worked the first time. I would definitely buy more of these high quality cables.
