Conntek 50A Generator Power Cord NEMA 14-50P to SS2-50R, 15 ft, STW Jacket, 12,500W

Conntek 1450SS2-15 is a 15-foot, 50-amp generator power cord that connects a NEMA 14-50 straight-blade outlet to a locking NEMA SS2-50 inlet, rated for up to 12,500 watts with an extra-heavy-duty STW jacket.

If you need a reliable link between a portable generator and a locking inlet or transfer switch, this cord provides a straightforward, durable solution. Built for generator-only use, the cable blends a robust STW jacket, an elbow-style plug for strain relief, and matching 50-amp connectors so you can safely transfer up to 12,500 watts of power where needed. It ships with a limited 1-year warranty and is sized to fit common RV, workshop, and backup power setups.

How does this cord fit different generator and inlet types?

The Conntek 1450SS2-15 is designed specifically to mate a NEMA 14-50P (straight blade, 50A, 125/250V) plug to a NEMA SS2-50R (locking-style, CS6365-compatible) receptacle. That makes it suitable for generators that offer a 14-50 outlet and for inlet or transfer switch boxes that accept the SS2 locking plug.

• Plug: NEMA 14-50P, 50A, 125/250V (straight blade)
• Receptacle: NEMA SS2-50R locking style, 50A, 125/250V
• Compatible with SS2/CS6365-style inlets used in transfer switches and RV inlets
• Not for permanent hardwiring — for generator-to-inlet connection only

What performance and durability features matter for long-term use?

This cable uses an STW-rated jacket for extra-heavy-duty protection against abrasion, oil, and outdoor exposure during normal generator operation. The elbow-style plug reduces strain at the connection point, while robust copper conductors and a 50-amp capacity support loads up to 12,500 watts when the generator delivers full rated voltage.

• STW jacket resists abrasion, oil, and weather during typical use
• Maximum wattage: 12,500 W at 125/250 V, 50 A
• Elbow plug improves cord routing and reduces connector stress
• Designed for repeated generator connections and seasonal storage

Are there safety or usage limits I should know about?

This cord is intended for generator connections only and should not be used as a permanent household wiring substitute. Avoid exposing connection points to moisture, debris, or standing water, and disconnect when not in active use or if the cable shows damage.

• For generator-to-inlet connections only; not for permanent external wiring
• Keep plug and receptacle dry and clean; inspect before use
• Disconnect after normal operation; do not leave connected unattended outdoors
• Limited 1-year warranty covers manufacturing defects under normal use

Who is this for: The Conntek 1450SS2-15 is aimed at homeowners, RV owners, contractors, and small business operators who need a dependable 50-amp generator connection to a locking inlet or transfer switch. If you have a generator with a NEMA 14-50 outlet and require a secure, heavy-duty cable to feed an SS2-style inlet for temporary backup power, jobsite equipment, or RV power hookups, this cord offers the rated capacity and rugged jacket to do that job safely and repeatedly.
