The front face was designed to extend downward and upward from the top and bottom of the painting chamber by two inches. The overhang on the sides would be one inch from the left wall and one inch from the right wall. In addition the front face was extended upward over the painting chamber to cover the box housing the light fixtures and wiring. This would provide a smooth, seamless appearance to the front of the paint booth.
This box houses three switches and one outlet. One switch is the on/off for the lights. The second switch is the on/off for the fan motor. And the third switch is the on/off for the female outlet directly under it. This outlet could be used to power an additional light source or other power tool needed for painting.
I plan to draw a more detailed electrical diagram to publish in a future update on this project. As with all electrical projects, do not perform tasks that you are not trained or otherwise qualified to do!
