C19 to C20 Power Cords
These heavy duty 20amp IEC C19 – C20 power cords are built to last in your server rack. They are available in a variety of colors so that you can easily identify critical equipment within the rack itself. UL listed and RoHS compliant, they are fully tested and guaranteed for a lifetime.

When to use C19 to C20 Power cords
The C20 configuration is the male version of the C19 configuration. They fit like together like two peas in a pod, like spic and span, like white on rice – you get the picture. Switches, servers requiring 15-20amps to operate properly utilize the C20 inlet in their power supply. In order to attach a power cord to this power supply, you will need a power cord with the C19 connector. Since this type of equipment is used within a data center rack, the power source is generally a PDU (Power Distribution Unit). The PDU can have C19 inlets, in which case you would need a C20 connector to plug into the PDU. Thus, the C19 to C20 power cord was born.
