The Power Cord Is Part of Your Design, Not an Afterthought: A King Cord Technical Guide
A power cord may be one of the last components considered in a product design. It should be one of the first.
The cord set affects safety approvals, enclosure geometry, serviceability, regional market access, and system reliability. A late change can force redesign work across the product. It may also require new agency reviews or re-certification.
That is why CTM Marketing, Inc. is pleased to introduce KING-CORD Co., Ltd. as the newest addition to our principal line card in the Rocky Mountain region.
King Cord manufactures and distributes A/C power cords, connectors, plugs, adapters, wires, and cable assemblies. Its product range supports IT equipment, office equipment, appliances, lighting, industrial equipment, medical applications, and other electrical products.
For engineers, the value is clear: specify the cord set during the design-in phase, not after the enclosure and compliance strategy are already fixed.
Why the Power Cord Is a Design Decision
A power cord is not simply a cable between a wall outlet and a product.
It is part of the product’s electrical and mechanical interface. Its selection can influence:
Input connector and inlet geometry
Clearance inside the enclosure
Current and voltage requirements
Grounding and polarity
Strain relief and cable routing
Environmental and material requirements
Country-specific safety approvals
Manufacturing and service processes
Final product certification
The correct cord set must match the equipment, the target market, and the intended operating conditions. A cord that is suitable for one configuration may not be suitable for another.
Engineers should confirm the connector family, plug configuration, cordage, current, voltage, approvals, and mechanical requirements before the design is released.
The Cost of Getting It Wrong Late
Late-stage cord changes often create more work than expected.
A different connector may require a new panel cutout. A different bend direction may affect the enclosure or cable routing. A regional approval requirement may force a change to the plug, cable type, or marking. A higher-current design may require a different connector family or cordage construction.
These changes can affect:
Early supplier and component review reduces these risks. It also gives the engineering team more options before the design is constrained.
King Cord’s Technical USP
King Cord brings broad product coverage and international approval experience to cord set selection.
The company was established in Taiwan in 1982. Its main production plant is located in Shenzhen, China, with sales presence in the United States, Europe, Taiwan, Japan, and the Middle East.
King Cord reports safety approvals from 29 countries. The company is certified to ISO 9001 and ISO 14001. It is also fully compliant with the latest editions of RoHS and REACH and is a certified Green Partner of Sony.
Its product categories include:
92 plug types
38 connector types
2 locking types
10 adapters
11 non-halogen types
17 wire and cable categories
2 charging gun products
This range helps engineers evaluate a complete cord set rather than selecting a cable in isolation.
IEC 60320 and NEMA Families
King Cord supports common IEC 60320 connector families used across electronic and industrial equipment.
C7
C7 connectors support 2.5A and 7A configurations, depending on the applicable regional version. Available voltage configurations include 250V and 125V.
C13
C13 connectors are available in 10A, 13A, and 15A configurations at 125V and 250V, depending on the specific product and approval requirements.
C14
C14 connector options support 10A through 15A configurations. Straight and right-angled versions are available for enclosure and cable-routing considerations.
C19
C19 connector options support 13A, 15A, and 20A configurations at 250V. These products are useful for equipment requiring higher current than a standard C13 configuration.
King Cord also supplies NEMA configurations such as:
NEMA 5-15P American plugs
NEMA 1-15P two-pin plugs
Japanese JIS C8303 configurations
Taiwanese CNS 10917 configurations
European EN 50075 configurations
Saudi SASO 2204 configurations

Application-Specific Cord Set Options
Medical and Hospital-Grade Cords
King Cord provides full UL-rated hospital-grade medical cords built to customer design.
Medical equipment manufacturers should define the required cord construction, connector configuration, approval markings, and end-equipment requirements early. The exact approval status depends on the specified part number and its integration into the finished product.
CTM can help engineering and procurement teams connect the application requirements with the appropriate King Cord configuration. Request the applicable datasheet and supporting documentation before final selection.
High-Amperage and Industrial Cords
Industrial equipment may require a cord set designed for higher power levels, demanding environments, or specialized connector interfaces.
King Cord supports high-amperage cord applications, including high-amperage IEC309 configurations. The correct selection depends on the equipment requirements, operating environment, regional standards, and installation conditions.
Do not select a high-amperage cord based on current alone. Review the full cord set, connector, cable construction, approval coverage, and mechanical interface.
EV Charging Products
King Cord’s charging gun line supports EV charging applications. The product range includes:
Up to 80A maximum
110–250V
Up to 20kW maximum power
J1772-to-Tesla adapter options
UL and CCC approved products
Confirm the exact product rating and approval documentation for the intended charging system. For current product details, review King Cord’s product listings.
Cordage and Material Selection
Connector selection is only part of the design. Cordage and material selection also affect the product’s performance, compliance, and production fit.
King Cord offers cordage families including:
SVT and SVTO
SJT, SJTW, SJTO, and SJTOO
ST and STW
H03VV-F and H03VVH2-F
H05VV-F and H05VVH2-F
VCTF and HVCTF
Non-halogen options include SPE, SVE, SJE, SJEO, and related SJEOOW families.
When evaluating cordage, engineers should consider:
Required current and voltage
Number of conductors
Conductor size
Flexibility and routing
Shielded or unshielded construction
Environmental conditions
Regional approval requirements
Halogen restrictions
Equipment inlet and strain relief
Assembly and service requirements
The King Cord wires and cables category provides a starting point for reviewing available construction families. Request full datasheets for final design decisions.
Plan for Global Approval Coverage
Products shipping to multiple regions need a clear approval strategy.
King Cord’s approval coverage includes agencies and standards associated with CCC, VDE, Australia/SAA, UL, CSA, Japan/PSE, SEMKO, FIMKO, DEMKO, NEMKO, KEMA, OVE, SEV, TUV, BSMI, and SASO.
The company’s international product coverage can help manufacturers reduce unnecessary cord set variation across markets. However, approval coverage is product-specific. Engineers should verify the applicable approvals for the exact cord, plug, connector, and cable construction.
Do not assume that one approval applies to every configuration in a product family.
Engineer’s Design-In Checklist
Use this checklist before releasing a cord set specification:
Define the target countries and regions.
Identify the required plug configuration.
Select the equipment-side connector or inlet.
Confirm current and voltage requirements.
Review grounding and polarity requirements.
Check enclosure space and cable exit direction.
Select straight or right-angled options where appropriate.
Confirm cordage and conductor construction.
Review halogen-free or non-halogen requirements.
Confirm medical, hospital-grade, industrial, or EV application needs.
Verify all required agency approvals.
Request the specific datasheet and approval documentation.
Confirm customer design and customization requirements.
Review samples before production release.
Request reliability test information when needed.
King Cord notes that its reliability test machine list is available upon request. This can support a more complete supplier review during qualification.
