Circuit Breakers and Plugs

The PDU plugs are appropriate for the power sources at the installation
sites:
• For installations within the U.S., the plugs are NEMA L6 30P, rated as
30A and 250V, and have two 16A circuit breakers with 20A trip values.
• For installations outside the U.S., the plugs are IEC 309, rated as 32A
and 250V, and have two 16A circuit breakers with 20A trip values.
