The minimum size parallel conductors permitted for elevator lighting is noted in Section 620.12(A)(1) of the 2011 NEC.

March 26, 2014

The minimum size parallel conductors permitted for elevator lighting shall be _____, provided the combined ampacity is equivalent to at least that of a 14 AWG conductor.

a) 20 AWG
b) 16 AWG
c) 14 AWG
d) 1/0 AWG

See answer and applicable Code reference

The correct answer is: a) 20 AWG

Section 620.12 of the 2011 NEC notes the minimum size conductor requirements for elevator cables. More specifically, as noted in 620.12(A)(1), "For lighting circuits, 14 AWG copper, 20 AWG copper or larger conductors shall be permited in parallel, provided the ampacity is equivalent to at least that of 14 AWG copper."
