Step 1: Match the Current Rating to the Wire Gauge
The most important rule in power cord selection: the wire gauge must support the current draw. A cord that is too thin will overheat.
| AWG | mm² | Typical Rating (US) |
|---|---|---|
| 18 | 0.82 | 10 A |
| 16 | 1.31 | 13 A |
| 14 | 2.08 | 15 A |
| 12 | 3.31 | 20 A |
For European harmonized cords, common equivalents are H03VV-F 0.75 mm² (10 A) and H05VV-F 1.0–1.5 mm² (10–16 A). Always confirm the final rating against the specific standard.
Step 2: Match Voltage and Plug to the Market
North America runs 120 V / 60 Hz; most of Europe, Asia, and Oceania run 220–240 V / 50 Hz. Check the plug types by country guide to select the correct plug and certification for your market.
Step 3: Match the Certification
Every market has its own safety mark: UL/cUL (North America), CE/VDE (Europe), SAA/RCM (Australia), KC (Korea), PSE (Japan), BIS (India). Using a non-certified cord can block customs and create liability.
Step 4: Choose Jacket and Application
Use PVC (H03VV-F / H05VV-F) for indoor general use, and rubber (H05RN-F / H07RN-F) for outdoor, industrial, or cold environments. For medical and data center use, specify high-temperature and shielded options where required.
Browse power cords by standard to find a certified cord that fits your specification.
