Single-Conductor Wire and Cable
Single-conductor wires and cables carry electrical signals between devices in industrial or commercial applications. Wires consist of one single electrical conductor, whereas a cable typically contains a group of two or more separate electrical conductors. However, these definitions vary based on the organization that regulates them such as IEEE, NFPA, IEC and UL. The two cables offered here, large gauge MTW cable and DLO cable, are single conductor but are not considered wires since they are defined as cables under their UL ratings.
Several insulation types of single-conductor wire and cable are available, including MTW, TFFN, THHN and AWM, to meet a wide range of application requirements.

Type MTW Wire
Machine Tool Wire (MTW) from Atlas Wire features a highly stranded conductor for more flexibility than other building wire and provides increased protection from moisture and corrosion. This 600V rated wire is typically used in control cabinets.
- Conductor sizes from 22 to 10 AWG
- Bare, annealed copper conductor per ASTM-B3, -B8 and -B787
- Color-coded, Polyvinyl Chloride (PVC) insulation that is heat-, moisture-, and flame-resistant
- Available in 500, 1,000, or 2,500 ft. spools (depending on wire size)
- Made in the USA
Starting at
(500 ft.)

Large Gauge MTW Cable
Direct Wire's ALL-FLEX MTW / THHW heavy-duty flexible power cable is ideal for industrial applications such as control panel power distribution, power feeds for variable frequency drives (VFDs), servo systems and motor leads in non-drive related applications. Other non-traditional applications include marine board applications and uninterruptible power supplies (UPS), transformer wiring, battery chargers, and more.
- Single conductor, in sizes from 8 AWG to 500MCM
- Various color options to fit your application
- Extremely flexible with a tight bend radius, allows easy installations in limited spaces
- Cut to length in 1-foot increments (10 or 20 ft. minimum depending on cable size)
- Made in USA
Starting at
/ ft. (20 ft. min.)
(MTW8BK-1)
Type THHN Wire
Thermoplastic High Heat Nylon (THHN) building wire from Atlas offers a PVC insulated nylon sheath for easy pulling and is intended for general purpose applications as defined by the National Electrical Code (NEC). This wire is appropriate for new construction or rewiring for 600V rated applications.
- Conductor sizes from 14 to 4 AWG
- Stranded, uncoated copper conductors per ASTM-B3, ASTM-B787 and ASTM-B8
- Color-coded, Polyvinyl Chloride (PVC) insulation that is heat, moisture, and flame resistant
