2020 National Electrical Code requires cellular metal floor raceways to be listed

As building ownership changes over time or as new technology emerges, the wiring or cabling required for use may also change. However, the cable distribution systems used to house the wiring or cabling need to remain safe for all types of applications.

To help ensure safety, the 2020 National Electrical Code (NEC) now requires cellular metal floor raceways toSource: UL be listed, per 374.6. Independently verifying a product’s compliance to meet and exceed new industry demands will provide manufacturers and suppliers with the confidence to enter and expand into new markets.

For U.S. certifications, the standard used to investigate products in this category is ANSI/UL 209, the Standard for Cellular Metal Floor Raceways and Fittings. These requirements cover cellular metal floor raceway systems intended to be installed as an integral part of the building structure and constructed for the installation of wires and cables in accordance with the NEC, NFPA 70. For Canadian certification, the standard used to investigate products in this category is CSA-C22.2 No. 79, Cellular Metal and Cellular Concrete Floor Raceways and Fittings.

UL certification services bolstered by a global network of technical experts and state-of-the-art facilities can help ensure the safety and quality of cellular metal floor raceway systems.
