3. Number of Loads GLPD-DIM-___-___-___-___
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. You can choose any number up to the maximums listed below. See page 18 for more information on the cabinet
sizes.
Cabinet Sizes
2x2 3x2 2x4 3x4 2x2-FT 3x2-FT
Maximum # of
Loads
DIM-MLO 24 36 48 60 - -
DIM-MCB 24 36 48 57* - -
DIM-FT - - - - 24 36
*If using 120/208V and 125A MCB, reduce the maximum number of loads shown by three.
4. Voltage
GLPD-DIM-___-___-___-___
To specify the circuit breaker voltage, enter “ 120 ” for 120/208V or “ 277 ” for 277/480V.
5. AIC Rating
GLPD-DIM-___-___-___-___
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
Note: For feed-thru cabinets only (-FT), the model name is complete after step three. Skip steps four and five.
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.
