We are in a debate on what should, or should not be used. I was told that we must use a metal face plate for Garage GDO's, yet, another electrician told me that it doesn't matter. Which is correct. Note: It made logical since at one point to use the metal, to protect the wires in the GDO's recepticle-if a fire was to break loose. (located in the ceiling of the garage--does not need GFCI protection).
