Optima 520 Series
For units with 5-20R outlets, any one outlet can carry a continuous load up to 16 Amps (with no draw on other outlets), or
a combination of outlets can draw a total of up to 16 Amps.
For units with C13 outlets, any one outlet can carry a continuous load up to 10 Amps (with no draw on other outlets), or a
combination of outlets can draw a total of up to 16 Amps.
24/30 A Rated Units (Groups 6, 7, 8)
All models with a 24/30 A inlet rating use the two breaker poles to power the line of two branches. Outlets are divided
between the two branches to provide greater total capacity. The total continuous load for all these models is 24 amps for
the whole PDU.
The two branches are mapped as follows:
•
Branch 1 — outlet Group B, plus the front outlets of Group A
•
Branch 2 — outlet Group C, plus the rear outlets of Group A

For Group 6 units with 5-15R outlets, each breaker branch is rated for 12/15 A. Any one outlet can carry a continuous
load up to 12 Amps (with no draw on other outlets), or a combination of outlets on one branch can draw a total of up to
12 Amps. The total for the whole PDU is 24 amps (the rating of the inlet connector, which happens to coincide withe the
sum of the branches).
For Group 7 units with 5-20R outlets, each breaker branch is rated for 16/20 A. Any one outlet can carry a continuous
load up to 16 Amps (with no draw on other outlets), or a combination of outlets on one branch can draw a total of up to 16
Amps. The total for the whole PDU is 24 amps (not 32!) which is the rating limit of the inlet connector.
For Group 8 units with C13 outlets, each breaker branch is rated for 12/15 A. Any one outlet can carry a continuous load
up to 10 Amps (with no draw on other outlets), or a combination of outlets on one branch can draw a total of up to 12
Amps. The total for the whole PDU is 24 amps (the rating of the inlet connector, which happens to coincide withe the sum
of the branches).
