10ft NEMA 5-15P to 5-15R Heavy Duty Power Extension Cord, 14AWG SJT 15A/125V, Black

The CableLeader PW167-12XX is a NEMA 5-15P to NEMA 5-15R heavy-duty power extension cord built around 14 AWG SJT cable. One end carries a standard three-prong NEMA 5-15P male plug, and the opposite end exposes a NEMA 5-15R female receptacle, wired line-to-line, neutral-to-neutral, and ground-to-ground for a direct one-to-one passthrough. Rated 15A / 125V / 1875W, it extends a grounded wall outlet to refrigerators, air conditioners, washing machines, and corded power tools that need a heavier conductor than a thin general-purpose cord provides.

The NEMA 5-15P plug is the familiar US three-prong connector found on nearly all 120-volt household and commercial equipment. Its two flat blades carry line and neutral while the round pin maintains protective earth, so any standard 15-amp grounded outlet accepts the cord without an adapter. The molded plug body resists pull-out during repeated insertion and keeps the blade spacing aligned with NEMA 5-15 dedicated and shared branch circuits.

At the load end, the NEMA 5-15R receptacle accepts any device fitted with a standard 5-15P plug, turning the cord into a true single-outlet extension rather than a connector adapter. Between the two ends runs 14 AWG (2.08 mm²) SJT cable with a 9.3 mm outer diameter. The 14-gauge conductor carries the full 15 amps with lower voltage drop than 16 AWG, an advantage that matters most on longer runs and high-inrush appliance motors.

Safety certifications cover both the cordage and the molded ends. UL file E204978 applies to the SJT conductor, UL file E210037 covers the molded plug, and the assembly carries cUL recognition for Canadian installation codes. RoHS compliance confirms the assembly is free of restricted hazardous substances, and the SJT jacket is rated VW-1 flame retardant at 300 volts and 75°C. The continuous ground path from plug pin to receptacle preserves equipment grounding for downstream loads.

Construction favors durability for demanding indoor service. The SJT thermoplastic jacket resists abrasion and flexing behind appliances and inside cabinets, and the molded strain-relief terminations lock the conductors and jacket into a single body with no screws or exposed wire. Because SJT is an indoor-rated jacket, the cord is intended for kitchens, laundry rooms, garages, workshops, offices, and equipment rooms rather than permanent outdoor exposure.

The black jacket offers a clean, professional appearance and hides scuffs and dust behind appliances, inside cabinets, and across garage or workshop floors.

Compatibility & Ordering Information — PW167-12XX works with any standard NEMA 5-15 grounded outlet and any device carrying a NEMA 5-15P plug, including refrigerators, freezers, air conditioners, washers, dryers, microwaves, power tools, and UPS or PDU units with standard US input plugs. The cord is available in multiple standard lengths to match in-room and across-room runs; select the length that fits your layout. Custom lengths, bulk packaging, and OEM kitting are available on request — contact CableLeader for quotations or private labeling.

FAQ

Q1. What is the difference between this SJT indoor extension cord and an SJTW outdoor cord?

This cord uses an SJT jacket, which is rated for indoor use and is not weather-resistant, while SJTW cords add a “W” rating for outdoor exposure to sun, rain, and cold. Both can use 14 AWG copper and carry 15A/125V, but only SJTW is suitable for permanent outdoor or wet locations. Use this SJT cord indoors — kitchens, garages, workshops, and equipment rooms.

Q2. What appliances can I run on a 14 AWG NEMA 5-15P to 5-15R extension cord?

It powers any grounded 120V device within 15 amps and 1,875 watts, including refrigerators, freezers, window air conditioners, washing machines, microwaves, and corded power tools. The 14-gauge copper handles high-inrush appliance motors better than 16 AWG. Always confirm the appliance’s nameplate amperage stays at or below 15A before connecting.

Q3. What gauge extension cord do I need, and how is 14 AWG different from 16 AWG?

For refrigerators, air conditioners, and power tools, choose 14 AWG: it carries the full 15 amps with less voltage drop and heat than 16 AWG, which is typically limited to 13 amps or lighter loads. The 14 AWG conductor in this cord supports 1,875 watts continuous, making it the standard choice for major appliances on standard 120V circuits.

Q4. Can I plug another extension cord or power strip into this one?

It is best to connect a single appliance or power strip directly to the NEMA 5-15R outlet rather than daisy-chaining multiple extension cords, which can exceed the 15-amp rating and create heat. Plug the NEMA 5-15P end into a grounded wall outlet, then connect one device or one surge strip to the receptacle, keeping total load at or below 1,875 watts.

Q5. Which length should I choose for my appliance setup?

Choose the shortest length that comfortably reaches the outlet, because shorter cords have less voltage drop under load. Short 1 ft to 6 ft runs suit refrigerators, microwaves, and bench tools near an outlet, while 10 ft and 15 ft handle across-room placement for air conditioners and washers. All lengths share the same 14 AWG, 15A/125V/1875W rating.
