6.13.3.2 The following conductors specified in Table 6.9.1 (CAN) or 6.9.2 (USA) shall be permitted to be
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.
