IEC Power Connector Chart: What C13, C14, C15, C19 & C20 Mean and How to Choose

June 08, 2026
Quick Answer

IEC 60320 connectors follow one rule: odd numbers (C13, C15, C19) are female connectors on the cord; the next even number (C14, C16, C20) is the male inlet on the equipment.

  • C13 / C14 — 10A (15A in North America), 250V, 70°C. Standard for PCs, monitors, switches, PDU outlets.
  • C15 / C16 — same 10A/250V but rated 120°C for heat. A C15 cord fits C16 and standard C14; a C13 will not fit C16.
  • C19 / C20 — 16A internationally, commonly 20A in North America (depends on certification). For servers, UPS and rack PDUs.

Most IEC cord mistakes do not show up at the bench. The cord seats, the device powers on, and everything looks fine—until a C13 cord
