Product FAQs
8 answersWhat does the "BC" suffix mean in the FA22020BC catalog number?
The "BC" suffix indicates the specific I-Line phase jaw configuration. This 2-pole breaker is designed to connect to the B and C phases on the panelboard bus.
Which panelboards are compatible with the FA22020BC circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards that accept F-frame plug-on breakers.
How does the FA22020BC mount into the panelboard?
It features an I-Line plug-on mounting style. The breaker jaws push directly onto the I-Line bus assembly, and a mounting bracket secures it in place, allowing for fast installation without individual wire connections to the bus.
What wire sizes are accepted by the lugs on the FA22020BC?
The factory-installed lugs accept 14 AWG to 4 AWG copper or aluminum wire.
Can I use the FA22020BC on a 480V system?
No. The FA22020BC is rated for a maximum of 240V AC. For 480V applications, a different breaker series or catalog number is required.
Is the Square D FA22020BC an obsolete breaker?
The FA series is a legacy F-frame circuit breaker. While exact replacements are still sourced for existing I-Line panels, facilities upgrading to modern equipment often substitute this with a PowerPact B-frame breaker, such as the BDA240204, using the appropriate I-Line mounting hardware.
What type of trip unit does the FA22020BC use?
It uses a fixed thermal-magnetic trip unit, providing long-time thermal protection against overloads and instantaneous magnetic protection against short circuits.
What is the maximum fault current the FA22020BC can safely interrupt?
This breaker has a standard interrupting rating of 10,000 Amps (10kAIC) at 240V AC. Ensure your system's available fault current does not exceed this rating to maintain proper safety compliance.

Ordered on a Saturday evening, paid for two day shipping and it arrived on time and in perfect condition. Would 100 percent be using this company going forward, beat out pricing and shipping times for all my local supply houses. Plus the staff were great to deal with.
- AHAnn H.Verified BuyerReviewingSquare D FA36100 - 100A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars8/22/26Professional Service
So far, so good! The circuit breaker was installed along with a new compressor for our church AC, and everything is now working well.
The company has been professional, dependable, and reputable throughout the process. I had a question after the installation, and it was answered immediately. I also appreciated that they followed up and asked for feedback to make sure the new part was working properly and that we were satisfied with the service.
It’s refreshing to deal with a company that not only has quality products but also cares about its customers after the job is completed. I would definitely recommend them!

The Square D FA32100 circuit breaker (refurbished) was as good as a new breaker, without exception. There was no wear and tear or any marks at all. It was basically new. It is an excellent choice and a great product without having to pay the cost of a new breaker.
