Hello again: Thanks for your comments on the PE Grounding!
This brings up amother question on protective coatings. I have been promoting painted and masked conductive coatings for the enclosures/chassis enclosures for both EMC reasons and Class I safety reasons. Typical enclosures employed are required to be NEMA 12 in our industrial applications. The mechanical engineers have been using clear iridited aluminum with paint masking or clear zinc cromate on the steel enclosures. The cost of masking and the zinc is questioned. Does anyone have some recommendations as to finishes that are good conductive protective coatings, durable, aesthetically pleasing and economical? It would be nice to become something other then a pain in future design reviews. Thanks again for your time? Best regards, Terry J.
