3. Number of Loads
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.
DIM-MLO
DIM-MCB
DIM-FT
*If using 120/208V and 125A MCB, reduce the maximum number of loads shown by three.
Note: For feed-thru cabinets only (-FT), the model name is complete after step three. Skip steps four and five.
4. Voltage
To specify the circuit breaker voltage, enter "120" for 120/208V or "277" for 277/480V.
5. AIC Rating
Choose one of the following values from the appropriate column to specify the Ampere Interrupting Capacity of the circuit breakers.
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.
