Example of PDU Usage Calculation
shows how to use the information from
to calculate the required
rack space and the current when the PDU is connected to a NEMA L6-20R receptacle
in the United States, with a voltage of 208V.
and the explanation that follows show how to use the information from
to determine when you need to buy an additional pair of PDUs or calculate
