240.21(b)(1)(4) .......the ampacity of the tap conductor is not less than 1/10th of the feeder OCPD protecting the feeder conductors.
The ampacity of the tap conductors is based on the 90 degree column or the 75 degree column?
300A OCPD protecting the feeder, tap conductors can not be less than 12 AWG or 10 AWG?
Thanks
