Insulation type MTW machine tool wire is now available in 22-gauge from AutomationDirect. Existing MTW wire sizes are 20 AWG to 10 AWG. The 22 AWG wire offers an 8% smaller diameter with a 3 A 600-V rating which is needed for many types of terminal block connections that cannot accept larger wire. MTW wire is designed and approved for use in industrial and commercial equipment.
Type MTW conductors are primarily used in control cabinets, in machine tool applications and in appliance wiring applications at temperatures from -25° to 105°C. MTW wire complies with the National Electrical Code (NEC) and NFPA Standard 79. Voltage rating for all applications is 600 V. MTW wire is sold in 500-ft spools and certain sizes are also available in 2500-ft reels.
Conductors are bare, annealed copper and the wire outer jacket is color-coded, Polyvinyl Chloride (PVC) that is flame-retardant and heat and moisture-resistant. Up to 10 solid and four spiral-striped wire colors are available depending on wire size and length.
MTW wire is UL approved, RoHS and CSA compliant and has a one-year warranty. 500-ft reels of MTW 22 AWG wire are $18.00.
