Conntek 50 Amp Generator Power Cord 25-Foot Black — NEMA 14-50P to Locking CS6364, Heavy-Duty STW Jacket

The Conntek 1450SS2-25 is a 25-foot, 50-amp temporary generator power cord that connects NEMA 14-50P generators to locking CS6364 inlets, rated for up to 12,500 watts with an extra-heavy STW jacket.

This heavy-duty generator lead is built for temporary power transfer between portable generators and transfer switch boxes or inlet panels that accept a locking CS6364 (SS2-50P/CS6365 compatible). It uses 6/3 and 8/1 gauge pure copper conductors and an all-weather STW jacket to resist abrasion, moisture, and temperature extremes during emergency, jobsite, or recreational use. UL listing and a one-year limited warranty back the cord’s construction and performance.

What connections and ratings does this cord provide?

The cord terminates in a straight-blade NEMA 14-50P male plug and a locking CS6364 female receptacle, supporting 50 amps at 125/250 volts. That combination makes it suitable for most generators specifying a 14-50R and inlet/transfer boxes using the SS2-50P/CS6365-style locking plug.

• NEMA 14-50P male plug (straight blade) — connects to many generators’ 14-50R outlets
• CS6364 locking female receptacle — locks into compatible transfer switch inlets
• Electrical rating: 50 A, 125/250 V, maximum 12,500 W

How durable and safe is the cable for outdoor generator use?

The cord uses STW-rated thermoplastic rubber jacket over pure copper conductors to withstand heavy-duty, temporary outdoor use. STW jackets are designed to resist moisture, oil, and physical abrasion; the copper conductors minimize heat buildup during extended runs under load.

• 6/3 and 8/1 gauge pure copper conductors for reliable current handling
• STW heavy-duty jacket for water resistance and abrasion protection
• UL listed construction for recognized safety standards

Which situations and generator setups is this cord compatible with?

Use this cord when you need to connect a portable generator’s 14-50R outlet to a locking inlet or transfer switch that accepts the CS6364/SS2-50P style plug. It’s intended for temporary power events like outages, RV shore power from generators, jobsite tools, and outdoor events where a 50 A connection is required.

• Temporary home backup during power outages — feeds a transfer switch or inlet box
• Recreational or RV generator hookups that accept NEMA 14-50
• Construction or event power where a 50 A locking inlet is used

How should I use and maintain the cord for safe operation?

Only use the cord for generator connections and disconnect it when not in normal use. Keep all connection points clean and dry, avoid kinks or sharp bends, and store the cord coiled in a dry place when not required. Regularly inspect for damage before each use.

• Intended for generator-to-inlet/transfer switch connections only
• Do not leave connected to a power source outside intended temporary use
• Inspect plugs, receptacle, and jacket for moisture, debris, or damage before use

Who is this for: The Conntek 1450SS2-25 is aimed at homeowners, RV owners, contractors, and event organizers who need a reliable temporary 50-amp generator power cable. If you require a sturdy, UL-listed 25-foot lead to connect a generator’s NEMA 14-50 outlet to a locking inlet or transfer switch—and want an STW-jacketed cord that handles up to 12,500 watts—this cable fits those needs. Choose this cord when you want a purpose-built, weather-resistant connection for short-term power transfer backed by a limited one-year warranty.
