Rating Label 

Each ASCO Series 300 Power Control System 
(PCS) contains a rating label to define the loads 
and withstand/closing ratings.  Refer to the label 
on the unit for specific values.   

 

For a non-redundant system where the load 
current is more than one generator’s full load 
current and the generators are paralleled to 
provide more power to the load, the main bus 
current rating must be equal to or greater than the 
sum of the two generator’s full load amps. 

 

If the application is a redundant system where the 
load current is equal to or less than the full load 
amps of one generator and the generators are 
being paralleled for redundancy, the rating must 
be equal to or greater than the full load current of 
the biggest generator.  In addition, the output 
circuit breaker must have proper overcurrent 
protection, equal to or less than the main bus 
rating label. 

 

 

Do not exceed the values on the rating label. 
Exceeding the rating can cause personal injury 
and/or serious equipment damage.
