Wiremold Garage Ceiling Outlet

Dear Mr. Electrician:  How do I install Wiremold surface metal raceway for an electrical receptacle outlet on the ceiling of my garage?    Answer:  In a few garages where there was already an electrical receptacle installed on the wall, I was able to add Wiremold 500 surface metal raceway to bring power to a ceiling outlet.  Below are some photos of a Wiremold metal surface raceway installation that was used to replace an extra long power cord that was tacked to the garage ceiling and wall for the garage door opener.  NOTE: Text links below go to applicable products on Ebay.com. One of the switches below was a 3-way for the garage light, the other a single pole for an outside light.  The existing outlet was not GFCI protected. Below is the "After" photo of the same switch and outlet location after installing Wiremold 500 for a ceiling outlet above the garage door opener. A Wiremold V5751-3 three gang extension box was used to attach onto the existing electrical box. In the above photo you can see the extra long power cord is tacked across the ceiling to an outlet on the inside front wall of the garage.

The existing wiring consisted of a three way switch for the garage light, a single pole switch for an outside light, and the electrical outlet that was not GFCI protected.  The LINE for the new GFCI outlet gets connected to the same wires from the outlet.  The wires from the new ceiling outlet get connected to the LOAD terminals on the GFCI.  The new switches get wired just like the old switches. I surmise that the rust on the screws was a result of these devices being mounted inside of an un-insulated outside wall.  There didn't appear to be any water infiltration. The three gang extension box base ring is attached to the existing wall box using 6/32 screws.  After installing the base plate it is possible to begin the wiremold installation.  The Wiremold 500 slips onto the short tongue on the base plate. Note the ground wire pigtail under the green screw.  It is not easy to see, but it is connected to the bunch of ground wires first, then wraps around the green screw and has enough left over to connect to the GFCI. A big blue wire connector was needed to tightly connect all of the ground wires together. The internal elbow is added to one end of the metal raceway and put into place.  After the elbow is secured a piece of raceway can be inserted at the other end. The short tongues on the back plate...
