if i am installing a 2 pole 30 amp breaker in my house, do i need an arc fault breaker for it or can i use a regular breaker?
and what would be the general rule for using arc fault breaker in a residential setting?
 
ARC faults are for certain applications.

Are you an electrician or DYI home owner?
 
I don't know what code cycle NYC is under. But look it up under 210.12

Here is the requirement for 2020 NEC

210.12 Arc-Fault Circuit-Interrupter Protection. Arc-fault circuit-interrupter protection shall be provided as required in 210.12(A), (B), (C), and (D). The arc-fault circuit interrupter shall be installed in a readily accessible location. (A) Dwelling Units. All 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets or devices installed in dwelling unit kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, laundry areas, or similar rooms or areas shall be protected by any of the means described in 210.12(A)(1) through (6):
 
As you can see above, they are for 15 and 20 amp circuits only. That is good, because you won't find a 30A arc fault breaker, especially a 2 pole one.

Did not mean any disrespect at all. Sometimes homeowners and DYI ask basic questions so we have to watch out for our answers.
 
Welcome to the world of AFCIs. Many electricans now just use the dual function afci/gfci, and get the panels with the plug on neutral buss. Saves wiring all the pigtails

What code cycle are you under, and what will this circuit supply?

NYC is under 2008 with amendments, unlike the rest of the state which is under the 2017. So local code for NYC may not have all the requirements for AFCI that the rest of the state has. Check with NYC codes.


Looks like they are in the process of reviewing and changing to the 2014 with amendments.
