UPDATE: I got a few valid criticisms of this video which I addressed in a followup: https://www.youtube.com/watch?v=eLUIK6IOw5Q
I had an exterior electrical outlet that was too small; in overall bad shape; and not very accessible. In this post, I describe how I extended the old single gang outlet a couple of feet with liquid-tight conduit to be more accessible and also upgrading it to double gang outlets.
