3. Number of Loads GLPS-___-___-___-___-___-___
Find the row in the table that matches your choices in steps 1 and 2. The numbers in blue represent the maximum number of loads for
each cabinet size. Choose a cabinet size, and do not exceed the maximums when designing the panel. See page 28 for more
information on the cabinet sizes.
Cabinet Size
Medium Large Extra Large
Maximum #
of Loads
HSW-MLO 30 32 42
HSW-MCB 27* 32 39*
SW-MLO 30 42 -
SW-MCB 27* 39* -
*If using 120/208V and 125A MCB, reduce the maximum number of loads shown by three.
4. Voltage
GLPS-___-___-___-___-___-___
To specify the circuit breaker voltage, enter “ 120 ” for 120/208V or “ 277 ” for 277/480V.
5. AIC Rating
GLPS-___-___-___-___-___-___
Choose one of the following values from the appropriate column to specify the Ampere Interrupting Capacity of the circuit breakers.
120 Volt 277 Volt
10K 18K
22K 35K
65K 65K
6. Door Option
GLPS-___-___-___-___-___-___
Enter “ ND ” to omit the local control access door. Otherwise truncate this from the model name.
What is AIC?
When a short circuit occurs, a large amount of current flows into the circuit breaker and it trips. The
Ampere Interrupt Capacity rating is the maximum current the breaker can safely interrupt. If the short
circuit current exceeds the AIC rating of the breaker, the circuit breaker may fail. For safe operation,
the AIC rating must exceed the available fault current at the panel.
