ECN Forum Forums Code Related Discussion NEC & other Code issues Difference between "Electrical Room" and "Clothes Closet"?

If you have an existing house with a panel in a "closet", what if you made them enclose the electrical panel inside of another "closet"? This way if there are sparks from the panel, the "smaller closet" around the panel will catch the sparks from falling onth "junk". Another way to look at it might be, having an electrical closet within a closet. Wouldn't that be safer? (Just a thought.)
