Wiring Method for Flexible Cord in Distribution Box

In the 2014 NEC ®, Section 400. 7 (11) allows a flexible cord to be run between an existing receptacle outlet and an inlet, where the inlet provides power to an additional single receptacle outlet. The wiring interconnecting the inlet to the single receptacle outlet must be a Chapter 3. Article 400 covers the general requirements, applications, and construction specifications for flexible cords and flexible cables. Code Change Summary: Language was added to describe a new way to use a flexible cord or cable. 400 requirements are essential for safety. We can see the various types of flexible cords. Flexible cords used with temporary and portable lights shall be designed for hard or extra-hard usage. The provisions of this paragraph do not apply to conductors which form an integral part of equipment such as motors, controllers, motor control centers and like equipment.
