12/18/2007


The national Electrical Contractors Assn. recently published NECA 420-2007, Standard for Fuse Applications (ANSI). The ANSI-approved standard describes installation and maintenance practices and procedures for low-, medium-, and high-voltage fuses.
The standard includes details about application data for fuses; sizing and selection; design considerations; installation; inspection; and maintenance. Installation guidance is complemented by troubleshooting information, fuse requirement summaries, and useful industry references.
“This Standard is the ideal complement to the other Power Distribution standards NECA has published this year,” said Caity Byrne, NECA’s associate director of standards. “From ampacity to welder protection, this new NEIS covers everything related to fuses used for overcurrent protection.” NEIS refers to the National Electrical Installation Standards published by NECA.
