I have the below cable in my garage and I am not clear if it is a two or a three wire cable. I was convinced it is a two wire but after researching I am now seeing it could be a three.

The most common type of cable used in houses is technically known as NMD 90 (Non-Metallic Dry service cable rated at maximum of 90 degrees Celsius). It is usually a plastic white covered cable. This cable comes with two or more conductors and includes a ground wire (bare wire). Your cable has 2 conductors and a ground.
