used without additional mechanical protection:

(a) flexible cord with insulation thickness equal to or greater than Type SPT-2;

(b) flexible cord with insulation thickness equal to or greater than Type SPT-1, routed through the chain of a chain pendant luminaire; or

(c) other conductors of minimum insulation thickness 0.80 mm (0.032 in), routed through the chain of a chain pendant luminaire.
