IEC C19 and C20 are high-current AC power connection standards in the IEC 60320 series. C19 is a robust female connector typically used for power cords. C20 is its mating male connector, used for mounting on equipment. Together, they form a reliable power coupling suitable for devices requiring higher currents than standard IEC connectors.
Designed to meet high power demands, C19/C20 connectors support currents up to 16A/250VAC, making them larger and more powerful than C13/C14 connectors. They are widely used in enterprise servers, data center PDUs (Power Distribution Units), UPS systems, network racks, and other high-power equipment with extremely high requirements for reliable AC power supply.

C19 C20 Outlet Inlet FAQ
C19 is a high‑current female connector (often on power cables), and C20 is the matching male equipment inlet. They are part of the IEC 60320 standard for AC power couplers used in higher‑power applications.
Under IEC standards, C19/C20 connectors are rated for about 16 A at 250 VAC. With North American UL/CSA ratings, they can be certified up to 20 A at typical mains voltages.
You’ll find them on data center servers, high‑power UPS and PDU units, large networking chassis, and heavy‑duty industrial electronics where a standard C13/C14 wouldn’t support the needed current.
C19/C20 connectors are physically larger and designed to safely deliver more current for power‑intensive systems, whereas C13/C14 are for lower‑power devices.
Yes, C19 and C20 connectors include a grounding pin as part of their three‑pole design for safety and proper earth connection.
Yes, because they follow the international IEC 60320 standard, equipment with C20 inlets can use region‑specific cord sets with C19 connectors on the cable end.
