Eaton NEC 2020 Code Changes Reference Guide
This document details the significant changes to the 2020 National Electrical Code (NEC) for residential and commercial electrical installations. It covers updates to Arc-Fault Circuit-Interrupter (AFCI) and Ground-Fault Circuit-Interrupter (GFCI) requirements based on dwelling unit area and specific locations, as well as changes to terminal connection torque specifications.
The guide provides a reference chart comparing AFCI and GFCI requirements across different room types and appliances for various NEC editions, culminating in the 2020 updates. It also explains the rationale behind the new terminal torque rules and lists specific Eaton circuit breakers and wiring devices designed to aid in compliant installation and inspection processes.
