The National Electrical Code (NEC) has officially included 14 AWG Copper-Clad Aluminum (CCA) as an approved conductor for 10-amp branch circuits in its 2026 edition. This significant update expands the acceptance of bimetallic wire, presenting new opportunities for builders, inspectors, and electricians across various construction sectors.
Historically, the minimum general-use branch circuit has been set at 15 amps, necessitating the use of 14 AWG copper or 12 AWG CCA or aluminum. As lighting efficiency has improved, particularly with the increasing adoption of LED technology, the demand on lighting circuits has decreased notably. In response to this shift, the NEC now allows the implementation of smaller, more resource-efficient 10-amp circuits specifically designed for dedicated lighting applications.
Using 14 AWG CCA wire addresses both performance and safety requirements while also conserving copper and stabilizing material costs. For electricians, this change translates into more competitive installation options without sacrificing quality. Builders and project managers can also expect greater predictability and peace of mind with these new circuits.
Enhancing Sustainability in Construction
The introduction of the 10-amp lighting circuit is more than just a code modification; it represents a strategic evolution in circuit design that aligns with contemporary energy-efficient lighting practices and sustainability objectives. As various jurisdictions begin to implement the 2026 NEC over the next few years, Copperweld is poised to support contractors with a robust line of CCA products that meet the latest code requirements.
