Created to provide a cleaner way to wire my custom 3 phase outlet boxes. The holders can be scaled a bit for exact fit to the connectors, I had to use 100% on 1 printer and 101% on another. They can then be slide into the backplate.
The boxes I used were 71695K41 from McMaster but should fit with most 2 gang electrical boxes from what I've seen.
The author marked this model as their own original creation.
