ABA member Copperweld is pleased to announce the inclusion of CCA in the UL-13 Standard for HVAC and thermostat cable applications.
In June 2020, Copperweld submitted a proposal to Standards Technical Panel STP-0013 with the intention of adding Copper-Clad Aluminum (CCA) to UL 13 — the standard for power-limited circuit cables. This would define CCA as a viable conductor option for Class 2, 150V-rated HVAC/Thermostat cable applications.
To achieve acceptance from the STP-0013, Copperweld conducted extensive electrical and mechanical testing, comparing the performance of 16 AWG CCA to 18 AWG copper conductors. With consensus from STP-0013 members, it was concluded that the results of this testing clearly demonstrated that Copperweld 16 AWG CCA 10% conductors perform equivalently or better than an 18 AWG solid copper conductor.
As a result of this work, Copperweld is pleased to announce the revision of UL 13, 4th Edition Standard with the inclusion of 16 AWG CCA for Class 2 HVAC/thermostat applications on March 18, 2022.
Later this year, Copperweld will be introducing a portfolio of UL 13-listed CCA thermostat cables.
