The issues with UPS products tripping GFCI breakers is due to leakage current that is out of spec for the GFCI circuit, this is almost always caused by the load

The issues with UPS products tripping GFCI breakers is due to leakage current that is out of spec for the GFCI circuit, this is almost always caused by the load attached to the UPS, not the UPS itself. While most UPS manufacturers do recommend against connecting it to a GFCI outlet, AFCI is required in all new construction for all circuits and GFCI is required for many circuits, including any circuits in basement areas which necessitates a dual function circuit. Since the original thread is about APC, even though I don't use their products, here's what they have to say on the topic: https://www.apc.com/us/en/faqs/FA369034/ https://www.apc.com/us/en/faqs/FA369034/ FWIW, running my server and network equipment never caused the breaker to trip erroneously while I was still living there. I sold the house when I moved cross-country for unrelated reasons so I can't say what happened afterwards, but my setup was installed according to code and functioned perfectly fine. I used quality UPS and decent quality network and server equipment. Cheap stuff may be farther out of spec and have more issues with leakage current.

> AFCI is required in all new construction for all circuits This is absolutely false. Though I'm sure you gave your electrician an earful and he did whatever was needed to keep his customer satisfied and happily took your money. Hope those $50 hospital-grade outlets are working well.

"For new construction, Section 210.12 (A) of the National Electrical Code states that all 120-volt, single-phase, 15- and 20-ampere branch circuits supplying all outlets must be Arc-Fault Circuit-Interrupter protected in the following dwelling unit locations: Kitchens, Family Rooms, Dining Rooms, Living Rooms, Parlors, Libraries, Dens, Bedrooms, Sunrooms, Recreation Rooms, Closets, Hallways, Laundry Areas, or Similar Rooms or Areas. Even though it is not listed, this includes finished basements because once the basement is finished, the area becomes one of the rooms listed above. Adding to the confusion, most people assume that outlets are only plugs or receptacles. However, outlets is defined in Article 100 of the National Electrical Code as “A point on the wiring system at which current is taken to supply utilization equipment”. That means that the requirements for AFCI protection is required in the areas stated above at all 120-volt, single-phase, 15- and 20-amp receptacles, lighting fixtures, switches, smoke alarms, dishwashers, refrigerators, and so on." So, yes, /technically/ it's not /all/ circuits, however please identify for me a room that's commonly found in a residential property that's not a Kitchen, Family Room, Living Room, Dining Room, Bedroom, Hallway, Laundry Area, Closet or "similar rooms or areas"? Look at the floor plan of most residential properties in the United States and every room noted on that floor plan is on the list. So /technically/ it's not /all/ circuits, so I was /technically/ incorrect, in practice what I said is absolutely true. Maybe a bit less snark from you and a bit more reading comprehension and you wouldn't come off as such a dick?

    You conveniently left out that few jurisdictions are on the 2020 NEC code cycle when this provision was introduced. New codes do not get adopted everywhere immediately. Your town or city needs to adopt it and that can take many years. So, no, not all new construction.
