What year was the first national electrical code document printed?

The first national electrical code document was printed in 1897. This document was significant as it established safety standards for electrical installations and aimed to reduce the incidence of electrical fires and accidents. The creation of the code was a response to the increasing use of electrical systems and the necessity for standard practices in installation and safety. The National Fire Protection Association (NFPA) developed this code, and it has since evolved into what is now known as the National Electrical Code (NEC), which is updated regularly to accommodate advancements in technology and changes in safety practices.
