Does anyone know specific cited code for strapping/supporting wiremold? I’ve attempted at locating manufacturers recommendations to be sourced to a pamphlet document. However, found the copies of the same document online from the manufacturer with different recommendations. The same document after the recommendations states to further refer to the manufacturers specs. THEN, clicking on the spec sheet link, forwards you to the same document. At the same time I’m being told different opinions by licensed journeyman from following metallic raceway code to a 30” rule. Is this an “inspector preference”, or is there legit information somewhere?
