Installing custom-made equipment correctly: before you install these systems, you better understand OSHA requirements

摘要

So you want to install a custom-made piece of equipment. But you don't know if you should-or if it's legal. Let's look at what requirements your equipment must meet. OSHA requires that all available electrical equipment be listed and labeled by a nationally recognized testing laboratory (NRTL). If such electrical equipment is not listed, labeled, and available, you can install custom-made equipment under certain conditions. However, the equipment must comply with requirements set forth by the assistant secretary of labor. It must meet the rules in OSHA 1910.399.
