US Power Cord

US Power Cords Built to North American Plug Standards

Ningbo Zhenjia Electric Appliances Co., Ltd. has manufactured electrical connection products since 2006, and the US power cord range is one of our core lines. We produce NEMA 5-15P, NEMA 5-20P, NEMA 6-15P and NEMA 6-20P assemblies with c(UL)us and ETL certified constructions, supplied as molded cords, open-end leads, extension cords and appliance harnesses for North American equipment.

Our position in this category is as a US Power Cord manufacturer working from customer drawings, samples or a defined working point: voltage, current, conductor gauge, jacket material, plug orientation and end termination. The range covers 18 AWG through heavy-duty constructions, two-pole and three-wire grounded versions, and both straight and angled plug bodies.

Molded Plug Assemblies

NEMA 5-15P and 5-20P plugs with PVC or rubber jackets, strain relief, optional fuse and open-end or connector termination.

Flat & Right-Angle Plugs

Low-profile 90-degree bodies for wall-hugging appliances, furniture, displays and equipment installed against a back panel.

Extension & Heavy Duty Cords

NEMA 5-15, 5-20, 6-15 and 6-20 extension assemblies for tools, shop equipment and outdoor-rated duty.

The Range We Supply

The models below represent the current US power cord program. Each one can be adjusted for cable length, conductor size, color, jacket compound and end termination within the certified construction.

How We Configure a US Power Cord

Configuration starts from the equipment interface, not from a stock list. We match the plug body to the outlet environment, then size the conductors and jacket to the load and routing conditions. The variables we work through with each customer are:

  • Plug type and orientation – NEMA 1-15P, 5-15P, 5-20P, 6-15P or 6-20P; straight, 90-degree flat or right-angle body.
  • Pole and wire count – 2-pole non-polarized, 2-pole polarized or 3-wire grounded with dedicated earth conductor.
  • Conductor gauge and material – 18 AWG through heavy-duty stranded copper, with gauge selected against current and voltage drop.
  • Jacket compound – PVC for general indoor use, rubber or waterproof compounds where abrasion or moisture is present.
  • End termination – molded female connector, IEC connector, stripped and tinned open end, ring terminal or fuse holder.
  • Length and color – cut to the routing requirement, with jacket color matched to the appliance or brand.

Electrical and Mechanical Limits

US power cords are rated by the plug and conductor combination, not by the appliance alone. A 15 A NEMA 5-15P assembly and a 20 A NEMA 5-20P assembly use different blade geometries and cannot be interchanged at the outlet. For 240 V equipment, NEMA 6-15 and 6-20 configurations carry the higher voltage without a neutral conductor. We confirm the working current, ambient temperature and flexing duty before fixing the conductor size.

Application Fit Across Equipment Types

Consumer Appliances

Flat and right-angle plugs keep the cord close to the wall behind refrigerators, microwaves, air conditioners and countertop appliances. Molded strain relief protects the conductor-to-plug transition during repeated handling.

IT and Office Equipment

Standard 3-prong NEMA 5-15P cords with IEC or molded female ends serve laptops, projectors, monitors and desktop systems where a grounded connection is required.

Tools and Commercial Loads

Heavy-duty 5-20, 6-15 and 6-20 assemblies support compressors, welders, shop tools and commercial equipment drawing higher current or 240 V supply.

Outdoor and Moisture-Exposed

Waterproof PVC and rubber-jacketed constructions with fused open ends suit lighting, pumps and equipment installed in damp or exposed locations.

Manufacturing and Quality Control

Our production base covers granulation, conductor processing, molding and assembly, which lets us control jacket compound and plug body quality from the raw material stage. The overseas manufacturing base operates under the ISO 9001 Quality Management System, and our US power cord models carry c(UL)us and ETL certification supported by compliance certificates E529560, E325763 and E321611.

Inspection covers conductor continuity, polarity, insulation resistance, high-potential withstand and dimensional checks on the plug body. Every production stage is subject to documented quality control protocols, and our in-house testing laboratory verifies finished assemblies before packing.

Related Product Families

US power cords sit inside a broader electrical connection program. Customers developing a complete accessory set often combine them with the following ranges:

  • Connector Type power cord – IEC and appliance coupler terminations for equipment inlets.
  • US Extension Cord – longer runs and multi-outlet configurations for North American supply.
  • Range And Dryer Cord – 3-wire and 4-wire high-current cords for major household appliances.
  • Generator Power Cords & Accessories – twist-lock plugs, inlet boxes and generator wiring cable.

Information We Use to Configure Your Solution

A precise quotation depends on the equipment interface and the production target. We prepare the configuration and price from the following inputs:

Input What We Need Why It Matters
Electrical rating Voltage, current, frequency, single or dual voltage Fixes plug type, conductor gauge and insulation class
Equipment interface Inlet type, panel opening, mating connector or open end Determines termination and strain relief design
Routing and environment Cable length, bend radius, indoor or outdoor, temperature Selects jacket compound and flex rating
Compliance target Required certification and marking Confirms the construction against the certified file
Commercial scope Order quantity, packaging, labeling, delivery destination Defines packing method and shipment scope

Drawings or physical samples are the fastest route to an accurate configuration. Where a customer supplies a sample, we reverse-engineer the plug geometry, conductor construction and jacket hardness, then produce to the same working point.

Customization, Packaging and Delivery Scope

Our R&D team develops and produces US power cords according to customer drawings or samples, covering non-standard lengths, custom jacket colors, branded plug bodies and specific termination requirements. Because we operate our own granulation and processing facilities, jacket compound formulation can be adjusted for hardness, flexibility and color without relying on an outside compounder.

Finished cords are packed to the agreed method, with PE foam or bag protection and strong cartons for export handling. Labeling, barcode and carton marking are produced to the customer specification, and shipment scope is confirmed against the order before dispatch.

Frequently Asked Questions

Which NEMA plug types do you manufacture for the US market?

We produce NEMA 1-15P, 5-15P, 5-20P, 6-15P and 6-20P configurations, in both straight and angled body styles. The 5-15 and 5-20 ranges cover most 120 V equipment, while 6-15 and 6-20 serve 240 V loads without a neutral conductor.

Can you supply cords with a fused plug or open end?

Yes. Fused plug versions such as ZJ-2F and fused open-end constructions such as ZJ-2FB are part of the range. Open ends can be stripped, tinned or fitted with ring terminals depending on how the cord terminates inside the equipment.

What certifications apply to your US power cords?

Our US power cord models carry c(UL)us and ETL certification, supported by compliance certificates E529560, E325763 and E321611. The manufacturing base operates under the ISO 9001 Quality Management System, and finished assemblies are tested before packing.

Can you produce a cord from our drawing or sample?

We develop and produce according to customer drawings or samples. Send the drawing, sample or a defined working point with voltage, current, length and termination, and we will confirm the construction and prepare the configuration.

What conductor sizes are available?

The range covers 18 AWG through heavy-duty stranded copper constructions. Conductor size is selected against the working current, cable length and allowable voltage drop, and is confirmed together with the plug rating.

How are the cords packaged for export?

Cords are packed to the agreed method with PE foam or bag protection inside strong cartons. Carton marking, labeling and barcode requirements are produced to the customer specification, and the delivery scope is confirmed with the order.
