Cerro Electrical®’s building wire is known for its outstanding quality and attractive combination of features. Building wire carries electrical current for external uses of power used in the construction of commercial, industrial, and residential properties. It is also used in power distribution applications, service entrance, and branch circuit applications for lasting installations. It is available in a variety of types, such as THHN/THWN, NM-B, and TFFN, and in different conductors, such as aluminum and copper.
Aluminum is as safe and reliable as copper. Listed connectors are evaluated and manufactured specifically for aluminum connections. AA-8000 conductors now have over 30 years of field installation proving their reliability. They have been recognized in the NEC for nearly 20 years.
AA-8000 series aluminum alloy conductors provide a safe and reliable method of designing and installing electrical systems. They are available as single conductors, in cable assemblies, and a variety of other configurations to meet the needs of different installations.
Copper wiring complies with every code, ordinance and regulation for electrical conductors throughout the United States. Copper provides more current carrying capacity for a given diameter of wire than any other engineering metal.
Because of its strength, copper resists stretching, neck-down, creep, nicks and breaks. All your connections will be solid with sturdy, copper and its flexibility makes it easy to join, while its hardness helps keep connections securely in place. The pure copper used in building wire will resist corrosion from moisture, humidity, industrial pollution and other atmospheric influences – to insure safe, trouble-free performance for the life of your system.
