The 2023 National Electrical Code (NEC) introduced several updates aimed at improving safety during service equipment installation and maintenance. One important addition is found in Section 230.62(C), which requires barriers inside service equipment.
The intent of this rule is straightforward: when technicians service load terminations with the service disconnect in the open position, they should not be at risk of coming into contact with uninsulated, energized busbars or service terminals. By requiring barriers, the NEC ensures that inadvertent contact with live conductors is prevented, reducing the risk of electrical accidents and making the work environment safer.
NEC 230.62(C): Barriers
"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 with the service disconnect in the open position."
In simple terms, this means service equipment must now include physical protective barriers that separate live parts from the areas technicians need to access during maintenance.
