*The total circuit length includes both welding and grounds leads (based on 4-volt drop) 60% duty cycle. | ||||||||
These values for current-carrying capacity are based on a copper temperature of 60°C (140°F), an ambient temperature of 40°C (104°F) and yield load factors from approximately 32% for the 2 AWG cable to approximately 23% for the 3/0 AWG cable. 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. | ||||||||
- Our copper cable is rated to 100% conductivity vs 61% for Copper Clad Aluminum (CCA) meaning you need 2 sizes larger for a CCA cable than you would if you used real copper.
- Copper is flexible and doesn't break easily but Copper Clad Aluminum (CCA) expands and contracts nearly 1/3 more than copper from heat. Add to that the fact that aluminum has around 37% of the tensile strength of copper and you have the potential for breaking strands and loosening connections...something you shouldn't mess with in high amperage DC Voltage applications!
- Copper Clad Aluminum was designed for AC voltage use especially in high frequencies like those found in signalling and telecommunications as AC current travels on the outside of the conductor so aluminum inside and copper outside meant an overall lighter weight and lower cost wire...but there is not a single benefit in DC voltage! It's a sad abuse by manufacturers to sell low quality cable dressed up as copper to unsuspecting buyers.
