Building Wire Cable THW 300 MCM Copper Conductor 37 Strands 600V

Building wire cable THW 300 MCM (Thousand Circular Mils) with a copper conductor consisting of 37 strands, rated for 600V, is suitable for high-current, heavy-duty electrical applications. The 300 MCM size provides a substantial ampacity, making it ideal for main service feeds, industrial machinery, and other demanding electrical loads. The stranded construction with 37 strands enhances flexibility, allowing easier installation around bends and in tight spaces compared to solid conductors. The THW insulation offers excellent heat resistance, moisture resistance, and durability, suitable for both indoor and outdoor use.

Cable THW 300 Application

The copper conductors type THW are used for power and lighting circuits in industrial, commercial and residential facilities where it is required of more security, just as it is specified in the National Electrical Code. This type of conductor can be used in dry and wet places; its maximum temperature of operation is of 75 ºC and its voltage of service for all the applications it is 600 V.

Cable THW 300 Standards

• ASTM B-3: Copper Annealed or Soft Wires.
• ASTM B-8: Copper Stranded Conductors in Concentric Layers, Hard, Semi-hard or Soft.
• UL - 83: Wires and Cables Insulated with Thermoplastic Material.
• NEMA WC-5: Wires and Cables Insulated with Thermoplastic Material (ICEA S-61-402) for Transmission and Distribution of Electric Power

CONSTRUCTION :

Cable THW 300 Construction

•Single conductor copper insulated with polyvinylchloride (PVC), solid or stranded, tinned or bare soft annealed copper per ASTM B-3, B-8, B-33, and complying with the physical and electrical requirements of UL standards 83 and 1851.
• Identified by surface marking indicate manufacturers identification, conductor size, voltage rating, and UL Type TW and THW designations.
