For decades, the minimum general-use branch circuit was 15 amps, requiring 14 AWG copper or 12 AWG CCA or aluminum. But as lighting efficiency improved — especially with the widespread adoption of LED technology — the load on lighting circuits has dropped dramatically. Recognizing this, the NEC now allows smaller, more resource-efficient 10-amp circuits for dedicated lighting circuits.

That’s where 14 AWG CCA building wire comes in. It provides the performance and safety the NEC requires while conserving copper and stabilizing material costs. For electricians, it means more competitive installations without compromising quality. For builders and project managers, it means predictability and peace of mind.

The 10-amp lighting circuit isn’t just a code change — it’s a smarter circuit design that aligns with today’s energy-efficient lighting and sustainability goals. As jurisdictions begin adopting the 2026 NEC over the next few years, Copperweld’s expanding CCA product line ensures contractors have a code-compliant option ready when they are.
