What constitutes a weatherproof box both indoors & outdoors? NEMA 3R & 4 & 4X are different. NEMA 3R doesn't seem to be fully weatherproof but 4 & 4x does.
How about indoor? If you needed to use a 4" ceiling junction box with blank cover what would be considered weatherproof? A cast FD or FS box I assume?
