In and, ANSI Device Numbers can be used to identify equipment and devices in a system such as, or. Many of these devices protect electrical systems and individual system components from damage whe. These numbers are based on a system that is adopted by a standard for automatic switchgear by Institute of Electrical and Electronics Engineers (IEEE), and incorporated in American Standard C37. This system is used with diagrams that are found in instruction books and in specifications.
