Q: In general, flexible cords other than tinsel cords shall not be smaller than No.?
Table 400.4, in the notes, states that 27AWG is for Tinsel cords, 20AWG is for Elevators only. Thus, that leaves 18AWG. Is this correct? Also, in the same article under OCP, it states that OCPD is required if 18AWG. Please explain and verify.
 
Not certain what you are asking to explain and verify...

You are asking an "in general" question" about flexible cord sizes which have moderately- to severely-restricted usage. First, note the statement of 400.2, then uses permitted and not permitted of 400.7 and 400.8 respectively. You'll likely get into further sizing restrictions upon consideration of other articles which apply to a particular situation.
