Effective Jan. 1, 2023, NEC 230.46 requires wire connectors used for splicing or tapping conductors on the line side of the service to be tested as suitable for this use.
NSI is pleased to announce that we are the first company to have UL-listed wire connectors for this new requirement. NSI is working to qualify all relevant connectors to meet the new NEC 230.46 requirement. Additional items will be added to this list as products are UL listed.
