Surge protection is now mandatory in accordance with NFPA 79 (2018 edition).
It should be obvious that Machine builders who export their products to North America are subject to the laws and regulations applicable there, and one of the most important technical standards relating to machines is the 2018 revision of the NFPA 79 standard.
What is NFPA 79?
The Electrical Standard for Industrial Machinery (NFPA 79) is a safety standard developed and published by the US-American organization National Fire Protection Association (NFPA). It contains requirements concerning electrical safety of industrial machinery. Every industrial machine which is produced in or imported into the USA, has to fulfil the requirements of the NFPA 79. If not, it is not allowed to be connected to the power supply network.
