Tip: Typical use is 15 A general lighting and receptacle circuits. Do not feed a 14/2 run from a 20 A breaker. Keep the inner bend radius at a minimum of 5x the cable diameter (about 1.9" here) so the jacket and insulation are not damaged. The individual conductors inside NM-B are not listed or marked as THHN and may not be installed apart from the complete cable.
