2 Product Overview
The SOOW 10/3 heavy duty portable cord is a UL62-listed, industrial-grade rubber portable cable built for high-current power supply to heavy equipment, portable machinery, and temporary power distribution systems. Rated 600V and 30 Amps, it delivers reliable power where flexible rubber cabling is required.
This 10 AWG 3-conductor cable features fully annealed bare copper stranding (104 strands × 30 AWG, Class K per ASTM B-174), providing the flexibility to coil, bend, and route repeatedly in construction and industrial environments while maintaining full ampacity at 30 Amps per NEC Table 400.5(a).
The EPDM rubber insulation provides robust dielectric performance at 600V, while the thick CPE (Chlorinated Polyethylene) jacket delivers industry-leading resistance to oil, solvents, ozone, UV radiation, moisture, and physical abrasion. This cable is classified for extra-hard usage per NEC Article 400, making it the standard choice for the most demanding portable power applications in North America.
Each production batch is high-voltage tested at 2500V and meets UL 62 and CSA C22.2 No. 49 requirements. Manufactured under the quality management system of SORIVO. For detailed company information, please visit sorivocable.com/about-us/.

5 FAQ
Q: What is the ampacity of 10/3 SOOW cable?
A: 10 AWG SOOW cable has a rated ampacity of 30 Amps per NEC Table 400.5(a) for 3 current-carrying conductors at 60°C ambient. Derating factors apply for higher ambient temperatures or bundled conductors.
Q: What is the difference between 10/3 SOOW and 12/3 SOOW?
A: 10/3 SOOW uses 10 AWG conductors (104 strands, 30A rating) while 12/3 uses 12 AWG (65 strands, 25A rating). The 10/3 has a larger outer diameter (0.66 in vs 0.595 in) and higher weight, suitable for equipment drawing 25-30 Amps.
Q: Can SOOW 10/3 cable be used for welding leads?
A: Yes. SOOW cable is commonly used for welding lead extensions. For the welding circuit itself, dedicated welding cable (Class M stranding) offers higher flexibility. SOOW 10/3 is ideal for the power input supply to welding machines drawing up to 30A.
Q: Is SOOW 10/3 suitable for outdoor and wet locations?
A: Yes. The CPE jacket is weather, UV, ozone, and moisture-resistant. SOOW is rated for indoor/outdoor use in wet or dry locations per UL 62. However, it is not rated for direct burial — use Type W cable for underground installations.
Q: What is the bending radius for 10/3 SOOW cable?
A: The minimum bending radius is 6× outer diameter for fixed installations (~4 in / 100 mm) and 10× OD for flexible/flexing applications (~6.6 in / 168 mm). Avoid sharp bends to prevent conductor damage.
