Great Stuff Expansion Foam
 

Our electrical panel is located in our attached one car garage. Above the panel where the coated wires enter the top of the panel alnog with the ground is a gap. Can Great Stuff expansion foam be safety used in this location to fill the gap to reduce any draft. My concern is if it is save to use around the wires and above the main panel.

Um
 

Look at their can, and visit the site for the expansion foam you bought, some ar fire retardent, others are flammable.
