答復(fù)：
8.4 When wires pass through a joint between sections of a portable luminaire that are separable for packing purposes, the joint shall be such that rotation of one section with respect to the other during the assembly of the sections is limited to not more that 360 degrees. Friction alone does not meet the intent of the requirement to prevent rotation.
Exception: When all of the following conditions exist, rotation between sections of a portable luminaire is not limited to 360 degrees:
a) The internal diameter of the tubing through which the wires pass is 1/2 inch (12.7 mm) or more or the Power Supply Cord Twist Test, Section 135A is conducted with acceptable results; and
b) The rotation during assembly is limited to not more than one revolution for each 3 inches (76 mm) of unobstructed tubing length through which the wires pass, when such rotation does not place any stress on the conductors; and
c) The conductors do not involve splices unless the splices are:
1) Inaccessible during assembly in accordance with Accessibility of Live Parts, Section 23; and
2) Secured and provided with strain relief that has been shown to be reliable and not easily defeated by the user.
