How Much Do You Know About Power Cord Types?

Power cords are essential components for any electronic or electrical device, but they are far from universal. Depending on the country, voltage requirements, or application, power cords come in many types and configurations. Understanding the different power cord types can help ensure safety, compliance, and functionality—especially in global manufacturing, shipping, or product design.

 Why Understanding Power Cord Types Matters

  • Electrical Safety: Using the wrong cord can cause electrical hazards.

  • Voltage Compatibility: Not all cords support the same voltage levels.

  • Regional Compliance: Different countries have different plug standards and certifications.

  • Product Design: If you’re a manufacturer, choosing the right cord is part of product localization.

Common Global Power Cord Types (By Region)

Type A / B – North America & Japan

  • Flat blade plugs.

  • Voltage: 100–127V

  • Plugged into standard wall outlets in the U.S., Canada, Mexico, and Japan.

Type C – Europe, South America, Asia

  • Two round pins.

  • Common in EU countries (excluding UK), South Korea, Indonesia, etc.

  • Voltage: 220–240V

Type G – United Kingdom, Ireland, Hong Kong

  • Three rectangular blades.

  • Fused for added protection.

  • Voltage: 230V

Type I – Australia, New Zealand, China

  • Two flat pins in a V-shape and a grounding pin.

  • Voltage: 230V

Type D – India, Nepal, some African countries

  • Three large round pins.

  • Voltage: 230V

✅ Tip: When buying or shipping electronics internationally, make sure the power cord is certified (e.g., UL, VDE, SAA) for the destination region.

Types of Power Cord Connectors

Not only do wall plugs vary—so do the connectors that plug into devices:

  • C7/C8 ("Figure 8"): For small appliances, speakers, and radios.

  • C13/C14: Common for desktop computers and monitors.

  • C19/C20: High power applications (e.g., servers, data centers).

  • NEMA 5-15P: Standard U.S. plug.

Industrial & Specialty Power Cords

If you're dealing with medical equipment, servers, or industrial machinery, specialized cords are often required:

  • Locking connectors (IEC-Lock)

  • Twist-lock plugs (NEMA L series)

  • Weatherproof or oil-resistant jackets

  • Shielded cables for EMI/RFI protection

How to Choose the Right Power Cord

  1. Check Device Requirements: Voltage, current, connector type.

  2. Confirm Country Standard: Plug type and certification.

  3. Measure Length & Gauge: Ensure cord can handle the amperage.

  4. Consider Certifications: Look for UL, VDE, PSE, SAA, CCC, etc.

Summary Table of Power Cord Types by Region

Region Plug Type Voltage Certification
USA/Canada Type A/B 120V UL, CSA
EU Type C 230V VDE, CE
UK Type G 230V BSI, ASTA
Australia/China Type I 230V SAA, CCC
Japan Type A/B 100V PSE

Conclusion

Whether you're sourcing electronics, designing products, or just replacing a laptop charger, knowing your power cords ensures compatibility and safety. With globalization and international trade, being cord-conscious is more important than ever.
