110.26(C)(2) applies to equipment over 1200A and over 6th wide. But there are other building regulations that dictate door swing being outward.
Thanks ! How is "other building regulations" and you share with me code name?

If the equipment is over 800 amps the door must swing out and be equipped with listed panic hardware. See 110.26(C)(3).
Great, Thanks！That means if equipment less than 800amps then the door could swing inside?

Yes, but other codes may apply, and which ones those are are best asked to the NJ AHJ.

In the 2017 NEC that section says 1200 amps or more. Has it changed for the 2020?
1200A should be 110.26(C)(2) and no chnages, for 110.26(C)(3) I saw no changes between NEC 2017 and 2020.

I think you are looking at (C)(2). Look at (C)(3). Occasionally you have the case where the door is more than 25' from the gear and this would not be required.
