Can you purchase a duplex receptacle orange in color that is not an IG receptacle. I have a client who wants to utilize orange receptacle for as a visual indicator from a specific system not necessarly isolated ground. however someone indicated it is a code violation to have an orange receptacle that is not isolated ground. Is this accurate I have been looking but cannont find any such code article orange tape for a high leg but thats it. so does such code exist? can you purchase an orange non-ig receptacle?
