Connector types
Local and national electrical codes specify the types of connectors that should be used when
interfacing with facility AC feeds. The location of the facility and the level, amount, and phase of the
AC power available determine the type of connector to use. PDUs are designed to distribute power at
a specific range and current. PDUs are provided with power cords of appropriate sizes and plug
types for the geographic region where they will be used. Table 1 shows profiles of the most common
connectors for different regions. Some regions may require connectors not shown in Table 1. Some
facilities may require PDU power cords without connectors for hard-wired (terminal) installations.
