In 2023, NFPA70B makes mandatory for Commercial and Industrial sites the inspection of ALL electrical equipment at least every 12 months, with equipment that meets the Equipment Physical Condition 3 requiring thermographic inspection at least every 6 months. Condition 3 includes equipment where urgent actions were identified in previous scans along with certain other circumstances.
NFPA 70B is a key document that drives electrical safety choices in the USA, including methods of electrical inspection, what kinds of equipment should or must be inspected, and who is qualified to inspect. It is important for companies in the USA to review this document and to incorporate the updated standards into their work practices.
