Electrical Wire from AutomationDirect

NEW: Some insulation types and gauge sizes are also now available in 2,500 ft. spool and reel lengths due to popular demand.

Please note that our prices on wire are closely tied to the market price for copper. This allows us to offer the best savings possible if conditions are favorable; however, it also means that our prices may increase if market conditions warrant.

Wire - Insulation Type MTW

Wire - Insulation Type THHN

General Purpose Applications

Type THHN building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). It is appropriate for new construction or rewiring for 600 volt applications. When used as type THHN, the conductor is suitable for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C in oil or coolants. When used as type MTW, the conductor is suitable for use in dry locations at 90°C, or not to exceed 60°C in wet locations or where exposed to oils or coolants.

• Sizes - 4, 6, 8, 10, 12, 14 AWG
• Spool / Reel Length - 500 ft.
• Conductors - stranded, uncoated copper conductors per ASTM-B3, ASTM-B787 and ASTM-B8
