Guide to the 2023 National Electrical Safety Codes

by | Nov 3, 2022 | 0 comments |

The National Electrical Safety Code (NESC) has been creating standards for electric and telecom utility companies since 1914. Every five years the code is updated, and the 2023 edition goes into effect on February 1st, 2023.

The goal of the updates is to protect workers, facilities, and the public during the installation, operation, and maintenance of communication and power supplies. It is edited and published by the IEEE Standards Association after receiving approval from the American National Standards Institute.

NESC codes are not the same as the National Electric Code. NESC codes focus on outdoor and below-ground equipment and structures. The National Electric Code applies to indoor wiring.

Here’s a brief look at the National Electrical Safety Codes for 2023 and who is affected.
