Product FAQs
6 answersWhat equipment is the HGA260904 circuit breaker designed to fit?
This breaker is built specifically for Square D I-Line panelboards and switchboards. It utilizes a plug-on I-Line connection on the line side to attach directly to the bus, with mechanical lugs on the load side.
Which legacy Square D breakers does the HGA260904 replace?
This PowerPacT H-frame breaker effectively replaces older FA and FH series I-Line breakers with a BC phase connection, including the FA26090BC and FH26090BC models.
What are the accepted wire sizes for the load lugs on the HGA260904?
The factory-installed mechanical lugs (part number AL150HD) accept either copper or aluminum conductors ranging from 14 AWG to 3/0 AWG.
Can the HGA260904 be used to backfeed an I-Line panelboard?
