This article covers 50' 8.

Overview

The Nassau Electrical Supply 50ft 8/4 SOOW power cable is a heavy-duty portable cord designed for demanding environments such as construction sites, event staging, and backup power distribution. With four 8 AWG conductors and a 600V rating, this cable can handle substantial loads while maintaining flexibility and durability. The SOOW (Service Oil-resistant Weather-resistant) rubber jacket provides excellent resistance to oil, moisture, and abrasion, making it suitable for both indoor and outdoor use. At 50 feet (approximately 15.2 meters), this cable offers plenty of reach for connecting generators to distribution panels or powering large tools and equipment. The 8-gauge thickness ensures low voltage drop over long runs, which is critical for high-draw devices like welders, compressors, and industrial machinery.

Connectivity & Compatibility

The 8/4 SOOW cable contains four color-coded conductors (black, white, red, green) that can be configured for various wiring schemes, including single-phase 120V/240V and three-phase 208V/480V systems. However, the cable comes without pre-attached connectors, so you will need to purchase compatible plugs and receptacles separately and terminate them properly. Common compatible connector types include: NEMA 5-15P / 5-15R (standard household 15A plug) NEMA L14-30P / L14-30R (30A twist-lock) NEMA L6-30P / L6-30R (30A 250V twist-lock) CS6364 / CS6365 (50A campsite connectors) The cable's outer diameter is approximately 13.5mm, so verify that your chosen cord grips and connectors are sized for this thickness. Because 8 AWG wire is thick, you will need appropriately sized crimp terminals and a heavy-duty crimping tool.

Product Info

This cable is sold by Nassau Electrical Supply and is available through . The price is around ¥56,000 as of September 2026, which offers good value compared to Japanese domestic cables of similar length and gauge. Market positioning is mid-range portable power cable, bridging the gap between consumer-grade extension cords and industrial permanent wiring. The SOOW rubber jacket is more flexible and durable than standard PVC, and it remains pliable even in cold weather. Warranty typically covers one year against manufacturing defects. The package includes only the bare cable; connectors and tools must be purchased separately.

Best Use Cases

Electricians and construction workers: The 50-foot length and 8-gauge thickness are ideal for temporary power distribution on job sites. The oil-resistant jacket withstands harsh conditions. However, you need the skills to terminate connectors yourself. Event production staff: Run power to outdoor stages, booths, and lighting rigs with a single long cable. Weather resistance allows use in rain. The cable is heavy, so it is not ideal for frequent repositioning. * Camping and RV enthusiasts: Connect a generator to your RV or campsite from a distance to reduce noise. 50 feet gives you flexibility in generator placement. You will need to install appropriate connectors for your specific setup.

Things to Consider

This cable is sold as bare wire without connectors. Unless you have electrical wiring experience, hire a qualified electrician to terminate it. Incorrect connections can cause fire or electric shock. The 8 AWG conductors are overkill for standard household 15A outlets. Use appropriate overcurrent protection (breaker/fuse) rated for your actual load. The 50-foot length may be excessive for small-scale wiring projects. In Japan, this cable does not carry the PSE mark, so its use may be restricted under the Electrical Appliance and Material Safety Law. Verify local regulations before using it for commercial or industrial applications. ## FAQ
Q: Can I plug this cable directly into a household outlet? A: No. The cable comes without connectors. You must install a compatible plug (e.g., NEMA 5-15P) using proper crimping or soldering techniques. Q: Is it safe to use outdoors? A: Yes. The SOOW rubber jacket is weather-resistant and oil-resistant, making it suitable for outdoor use. However, prolonged direct sunlight exposure may cause UV degradation; consider using a protective cover. Q: Can I use this cable for three-phase 200V equipment? A: Yes. The four conductors support three-phase four-wire systems (three power lines plus ground). Always verify that your equipment's current draw does not exceed the cable's ampacity (approximately 40A for 8 AWG).
