AF breaker stays tripped
 
I wired a duplex building with little assistance from a licensed electrician who would let me do it under his license.

Anyway, I wired two different circuits, one on each side of the duplex. Both circuits are for bedroom plugs which have about 13 receptacles on each circuit. I daisy chained 14-2 from the panel to the plugs and used a 15 amp arc fault breaker. These are two identical circuits, just in different units of the duplex. I got the power turned on to the building and everything worked except these two circuits so I think I must have done something wrong. Any ideAs what it could be? Why would the arc fault breaker stay tripped, is there a chance that a drywall screw may have hit the wire somewhere on both sides causing this?

Thanks in advance.

How is the breaker wired? Did you put the neutral from the circuit to the breaker and the neutral from the breaker to the neutral bar?

Other than that, it could be

Bad breaker
Bad wiring (screw thru romex, bad splice, bad backstab)
Something plugged into the circuit that has a fault.

Yes the neutral from the circuit goes to breaker and neutral on breaker goes to neutral bar.

If the breaker is tripping, and not able to be reset, then you have a short somewhere.

Which could be anything from bad splice or connection, or maybe a screw or nail is making contact with a hot or neutral wire?

Are you asking us, or telling yourself what it could be.

All or any one of the above.

Also, attaching the neutral from the new circuit to a neutral from another circuit can cause the tripping of the arc fault breaker.
