NEC 2023 Changes: Multioutlet Assemblies and Flexible Power Distribution

NEC adoption varies by jurisdiction, so always verify what your AHJ has adopted and whether local amendments apply. This guide focuses on the field-level impact electricians care about most.

What changed in NEC 2023

NEC 2023 includes refinements that affect modern flexible distribution systems used in offices, labs, and reconfigurable spaces.

Why it matters for electricians

Frequent space reconfiguration increases risk of field modifications that drift from listing and installation instructions.

Before vs. after (quick comparison)

Field view Before After

Inspection risk Moderate inconsistency between crews and inspectors Tighter expectation for documentation and consistent application
Jobsite impact Corrections often found late at trim/final Better outcomes when code path is planned at design and rough-in
