I need a quick answer on what I hope is a simple question. I don't know Article 501 very well, and I didn't see my answer there.
My issue relates to a shipboard application, so the NEC does not apply. The rules that do apply do not distinguish between "Class I, Division 1," and "Class I, Division 2." All they say is that a specific area is classified as "hazardous," by virtue of flammable liquids and vapors.
Here's the question: The owner issued a spec said that a transformer must be "explosion proof." The supplier gave the owner a "Class I, Division 2" transformer. Did this transformer meet the spec?
I think not. But I would like to have an NEC citation to back up my response to the owner.
