The particular label shown here identifies that each outlet is
rated at 10 amps. This means that any installed device using
that outlet can not draw more than 10 amps of current. This
label also identifies that the PDU is split up into two 16-amp
zones protected by a circuit breaker. If the PDU was to have
one 10 amp device and three 2 amp devices plugged in, the
other outlets in the zone must remain vacant. Another example
might be six 2.2 amp devices plugged into this zone. This
would result in 13.2 amps of total current draw, which is under
the 16 amps per zone requirement.
Total current draw should not exceed 80% of the rated (30
amps) current draw for the PDU. The label (on the right)
identifies that the entire PDU has already been derated to 24
amps to meet this requirement.
