California Electrical Code Update: Servicing Receptacle Requirements in Group R-2 Occupancies

Recent revisions to the California Electrical Code (CEC) and the National Electrical Code (NEC) are streamlining requirements for servicing receptacles in multi-dwelling unit buildings, specifically Group R-2 occupancies. These changes, effective March 4, 2026, aim to simplify compliance and address impracticalities found in previous code versions.

Background: Previous Code Requirements

The 2022 and 2025 California Electrical Codes, referencing Article 210.8(E), mandated that equipment requiring servicing be equipped with Ground Fault Circuit Interrupter (GFCI) type receptacles. Article 210.63 specified requirements for servicing receptacles in areas with mechanical or dedicated electrical equipment, excluding residential Group R-3 occupancies. However, a provision within 210.63(B)(2) prohibited connecting the servicing receptacle circuit to the load side of the served equipment, a requirement deemed infeasible and impractical by industry professionals.

The 2026 NEC Revision and its Impact

The 2026 National Electrical Code (NEC) addresses these concerns with a revised Article 210.63(B), which now reads:

“Within other than dwelling units, a receptacle outlet shall be required for wiring systems that include a solidly grounded system operating at less than 150 volts to ground. The receptacle outlet shall be located within the same room or area as indoor switchboards, switchgear, panelboards, motor control centers, and service equipment.”

This updated language eliminates the requirement for servicing receptacles in residential units. The California Electrical Code will now allow the use of Article 210.63(B) of the 2026 NEC as a basis for simplifying compliance, replacing the more restrictive provisions of the 2022 and 2025 CEC.

Key Takeaways

• The 2026 NEC simplifies servicing receptacle requirements in Group R-2 occupancies.
• The previous prohibition on connecting servicing receptacle circuits to the load side of served equipment has been removed.
• California will adopt the 2026 NEC’s Article 210.63(B) for compliance purposes.

Looking Ahead

These changes represent a move towards more practical and achievable electrical code compliance in multi-dwelling unit buildings. Electrical contractors and building inspectors can now utilize the clarified guidelines of the 2026 NEC to ensure safe and efficient electrical installations.
