Copper Where It Counts

Upgrade your building wire

Copperweld® Building Wire is a Copper-Clad Aluminum (CCA) bimetallic conductor that, when installed to NEC requirements, offers greater current-carrying capacity than its alternatives.

Considering its specific rating in Code, testing has shown that Copperweld CCA is the most energy-efficient conductor with the lowest voltage drop on the market. This offers energy savings to owners of homes and buildings, performance enhancements, and energy conservation for the good of society.

Copperweld Building Wire Benefits

Copper is a valuable resource. When sized appropriately, Copperweld CCA conductors utilize 1/6th the amount of copper of traditional copper conductors for the same-sized circuit while delivering lower voltage drop and improved energy efficiency.

Reduces Theft Incentive

CCA offers a fraction of the scrap value of copper building wire.

Energy Efficient

When sized per Code, CCA delivers improved energy efficiency over alternatives.

Easy to Install

CCA is lightweight, flexible, and terminates to standard torquing values.

Code Compliant

NEC compliant for 600 Volt residential branch circuit conductors since 1971.

Safety Tested

Listed for safety for use in general electrical wiring and branch circuits.

Proven Performance

CCA has 50 years of safe performance history in standard circuits.
