Product FAQs
6 answersCan I install the FY14030B in a standard QO or Homeline load center?
No, the FY14030B is an I-Line style plug-in breaker. It is strictly compatible with Square D I-Line panelboards and switchboards and will not fit in residential QO or Homeline load centers.
What does the 'B' in the FY14030B catalog number mean?
In Square D I-Line nomenclature, the 'B' suffix indicates that this 1-pole breaker is factory-configured to connect specifically to the B-phase bus bar in the panelboard. If you need to connect to the A-phase or C-phase, you would need the FY14030A or FY14030C, respectively.
How does the I-Line connection work on the FY14030B?
The breaker features a plug-on line-side connection that engages directly with the I-Line bus stack in the panelboard. The load side utilizes a standard mechanical lug for wire termination.
Is the FY14030B a current production model?
The FY series is a legacy F-frame molded case circuit breaker. It remains a popular drop-in replacement for maintaining existing I-Line panelboards, though Square D has transitioned to the PowerPact B-frame series for newer installations.
Does the FY14030B provide GFCI or AFCI protection?
No, this is a standard thermal-magnetic breaker with fixed long-time and instantaneous (LI) trip functions. It does not provide ground fault or arc fault circuit interruption.
Is the FY14030B HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
