Safety & Compliance :: Copperweld

Safety is our standard

Product Safety Listed, NRTL Performance Tested, and referenced by the NEC since 1971, Copperweld Copper-clad aluminum (Cu-clad) conductors have proven themselves. We are proud members of the International Association of Electrical Inspectors (IAEI) and The National Fire Protection Association (NFPA). Through these organizations, we take an active role in assuring electrical safety in society.

Safety without compromise

In Code since 1971

Cu-clad conductors have been referenced by the NEC for decades. This milestone was achieved due to extensive fact-finding studies by Underwriters Laboratories (UL) which proved CCA’s safety for use as a conductor material. UL's fact-finding studies established that CCA performs equivalently to copper for electrical connections with such devices as receptacles and snap switches.

Product safety listed by NRTLs

Copperweld building wire is listed for product safety by Nationally Recognized Test Laboratories (NRTLs) to industry standards. As a requirement of the NEC, all building wire must be listed for safety assurance.

Cooler points of termination

Due to its favorable ampacity rating within the NEC, Copperweld conductors have less heat rise at points of termination and splices than do equivalently rated copper and aluminum conductors. Less heat at points of electrical connection favors improved equipment performance, longer service life and safer installations in general.

Manufacturer’s identification for proper usage

Due to empirical data derived from 50 years of real-world usage of Cu-clad conductors, in addition to years of third-party fact-finding and performance testing, Copperweld identifies its building wire for use with standard terminals and splice connectors suitable for use with copper. In terms of electrical connections, CCA and copper are generally equivalent with few exceptions.
