Welding cable ampacity.

Wire and cable your way po box 603 highland park il 60035. In actual service the load factor may be much higher than indicated without overheating the cable as the ambient temperature will generally be substantially lower than 40 c. The sizes of cables generally used range from 2 awg to 3 0 awg. All of our welding wire options feature superior flexibility and durability performing as professionally as the people who use them.

Allowable ampacities of insulated conductors rated 0 2000 volts as excerpted from the 2002 national electrical code ampacities of not more than three current carrying conductors in raceway cable or earth. Southwire excelene welding cable extra flexible rated for 50 c to 105 c temperatures. This cable used for secondary voltage resistance welding cable leads national electrical code article 630 electric welders and for temporary power industrial applications. Suggested ampacities for 600 volt in line applications.

West coast sales office. In actual service the load factor may be much higher than indicated without overheating the cable as the ambient temperature will generally be substantially lower than 40 c. In actually service the load factor may be much higher than indicated without overheating the cable as the ambient temperature will generally be substantially lower than 40c. These cables are used by professional welders for secondary voltage resistance welding leads and as a power supply for welding tools and applications that do not require over 600 volts ac.

Welding cable ampacity is a common source of confusion because it is calculated differently than other types of wire and therefore appears to have a higher ampacity than products such as building wire or tray cable but these ampacities are for welding applications only.
