Product FAQs
8 answersWhat panelboards accept the HGA36080LC circuit breaker?
It is exclusively compatible with Square D I-Line panelboards and switchboards. The I-Line design allows the line side of the breaker to plug directly into the panelboard bus assembly, eliminating the need for line-side wire terminations and speeding up installation.
Can I install the HGA36080LC in a standard residential load center?
No, the HGA36080LC features an I-Line plug-in mounting style and will not fit in standard Square D QO or Homeline residential load centers. It is strictly designed for commercial and industrial I-Line panelboards and switchboards.
Why does the HGA36080LC require copper wire?
The "LC" suffix in the catalog number indicates this breaker is factory-equipped with copper-only lugs. Using aluminum conductors will violate the listing and could cause a hazardous connection failure. You must use copper wire sized from 14 AWG to 3/0 AWG for the load-side terminations.
Can I adjust the trip settings on the HGA36080LC?
The thermal, or long-time, overload protection is fixed at 80 amps and cannot be changed. However, the magnetic, or instantaneous, short-circuit trip threshold is adjustable. This allows electricians to fine-tune the breaker's response to inrush currents or specific fault conditions.
Can the HGA36080LC replace older Square D circuit breakers?
Yes, the PowerPacT H-Frame series is the modern replacement for legacy Square D F-Frame breakers. The HGA36080LC can directly replace older FA36080 and FH36080 I-Line breakers, fitting into the exact same panelboard space.
Is the HGA36080LC suitable for direct current (DC) applications?
Yes, in addition to standard AC systems, this thermal-magnetic breaker is fully rated for DC power distribution. It provides up to 20kA of interrupting capacity at 250VDC and 500VDC, making it suitable for industrial DC control panels or specific renewable energy applications.
What does the "G" in the HGA36080LC part number signify?
In the Square D PowerPacT nomenclature, the "G" designates the breaker's interrupting rating tier. For this model, it indicates a capacity of 65kA at 240V and 35kA at 480V, which is suitable for commercial and industrial systems with moderate available fault current.
What does the "A" in the HGA36080LC catalog number mean?
The "A" indicates the breaker features an I-Line plug-in connection on the line side and traditional wire lugs on the load side. This specific configuration is required for installation in Square D I-Line panelboards.
