Has anyone had to provide washdown/hosedown rated device covers in commercial kitchens? Just wondering what IP/NEMA rating that would fall under, 3R is not sufficient, so standard WP or in-use covers need not apply. 4X seems to be an overkill. Something marine grade is probably what I need, I just can't find a decent looking cover for duplex and/or GFI receptacles, and toggle switches. Anybody had experience with this?
