Building and Fixture Wire is part of Allied Wire and Cable's extensive stock of Hook-Up and Lead Wire. Our Building Wire is ideal for use in a wide variety of applications in accordance with the National Electric Code. These fixture wires are suitable for use as general-purpose wiring in machine tools, appliances, and control circuits. They may also be installed in conduit and other raceways.
Our catalog of building wire includes TFFN & TFN Wire, THHN Wire, and RoHS Compliant THHN Wire. All of our building wires feature PVC insulation and a Nylon jacket. They also have bare copper conductors and meet multiple UL Styles. All three wires have a voltage rating of 600V and a maximum temperature of 90°C. The main difference between these wires is their conductor stranding.
Our TFFN wire is available with both solid and stranded conductors. This copper wire has the thinnest PVC insulation of our building wires. It meets UL Style 1316, UL 1408, UL 1452, and UL MTW. It is also CSA type TWEN approved and available in 16 AWG and 18 AWG. Both our THHN and RoHS Compliant THHN building wires feature finely stranded copper conductors. These building wires are available with a wide variety of insulation thicknesses that vary depending on gauge size. Both meet varying UL Styles, including UL 83, UL 1063, UL 758, UL 1581, UL 1063, and UL MTW. Our THHN Wire is available from 1000MCM to 14 AWG and our RoHS Compliant THHN wire is available from 250 AWG to 14 AWG.
Along with our large catalog of building wire, we also offer an extensive stock of XHHW wire, RHH/RHW/USE-2 specialty wire, and MTW (Machine Tool Wire) Wire that meet the National Electric Code standards. Our XHHW-2 wire is available as both aluminum and copper wire. These wires all share similar voltage and temperature ratings.
