Type UF-B
CCA Building Wire

Identification, applications and usage

Copperweld^® Copper-Clad Aluminum Type UF-B (non-metallic sheathed cable) is referenced by Article 334 of the National Electrical Code. OSHA safety listed: UL E539738. ETL listing: 5021266.

Wiring Methods: Per Article 340 of the NEC, Copperweld® Type UF-B may be used for underground locations and directly buried without the use of conduit.  It may be used as single-conductor cables. Where installed as single-conductor cables, all conductors of the feeder or branch circuit, including the grounded conductor and equipment grounding conductor, if any, shall be installed in accordance with 300.3.  It may be used for wiring in wet, dry, or corrosive locations as a nonmetallic-sheathed cable. Where so installed, the installation and conductor requirements shall comply with Parts II and III of Article 334, except for 334.12(B), and shall be of the multiconductor type.  UF-B cables may be used as single-conductor cables as the non-heating leads for heating cables as provided in 424.43.  UF-B cables may be supported by cable trays. Type UF-B cable supported by cable trays shall be of the multiconductor type.  Consult Section 340.12 of the NEC for uses not permitted for Type UF-B cable.

Copperweld^® UF-B cable is identified for use with wiring devices, splice connectors and equipment terminals rated for Cu, Cu/Al and CO/ALR. When terminating with twist-on splice connectors, pre-twisting is not recommended. Torque until the wires are tight under the cap and visibly twisted together two times outside of the cap to ensure electrical contact. Do not over-torque or under-torque. Ensure secure connection limiting wire deformation. Copperweld^® UF-B cable is made with ASTM B-566 CCA bare wire, which carries its own component listing, RU DVVV2. Copperweld UF-B conductors are suitable to terminate on 15 and 20 ampere rated wiring devices (receptacles and snap switches) marked ‘copper only’ or ‘CO/ALR’. For termination on devices rated 30 amperes or greater, the termination must be marked ‘CU/AL’ or equivalent. Please consult UL Product IQ guide information RTRT and WJQR if further confirmation is required. Copperweld^® CCA conductor satisfies Article 110.14 Electrical Connections as being a similar metal to copper for the purposes of electrical connections. Copperweld^® UF-B may be pigtailed to single-metal copper wire in dry locations. Copperweld^® UF-B cable should not be terminated with single-metal aluminum wire without the application of an oxide inhibitor and a terminal or connector specifically listed for the intermixing of dissimilar conductor metals. Copperweld^® ASTM B-566 CCA wire is not dissimilar to copper, brass or zinc plated steel.
