About the Guide

Scope, Purpose and Cautions

This Guide was developed to convey the primary changes to the 2023 NEC when compared to the 2020 NEC. This enables electrical and low-voltage professionals to keep informed and stay in Code compliance from one Code cycle to the next. Articles covered primarily relate to Wiring Devices and Communications Systems with limited discussion of Over-Current Protection, Raceways, Wires, Luminaries, Emerging Markets and other mainstream requirements.
