Would it be a code violation to modify an 250watt explosionprooof lighting fixture to a 400watt. a new ballast and globe were installed to make it a 400. The argument is that it is still an explosionproof fixture and everything fit. I do not agree with this method, because this is not the watts designed for also the nameplate will no longer be accurate. I can not find it in the code but isn't there something about modifying equipment. Thank You for your time & help!
