Here is an example of one of the changes that are not GFCI or AFCI:
2017 NEC Requirement:
Previous requirements located in article 408.3(A)(2) – Service Panelboards, Switchboards, and Switchgear – Barriers shall be placed in all service panelboards, switchboards, and switchgear such that no uninsulated, ungrounded service busbar or service terminal is exposed to inadvertent contact by persons or maintenance equipment while servicing load terminations.
Exception: This requirement shall not apply to service panelboards with provisions for more than one service disconnect within a single enclosure as permitted in 408.36, Exceptions 1, 2, and 3.
2020 NEC Change:
Barriers shall be placed in service equipment such that no uninsulated, ungrounded service busbar or service terminal is exposed to inadvertent contact by persons or maintenance equipment while servicing load terminations.
RATIONALE OF CHANGE:
Article 230.62(C) pertaining to barriers was original language from Article 408.3(A)(2) for barriers on service panelboards, switchboards, and switchgear installations now moved to article 230 for Services. This requirement for prohibiting possible inadvertent contact of service busbars and service terminals while conducting maintenance load terminations is now under Article 230 in order to umbrella across all service equipment.
