Code Quiz: Article 400

Based on the 2014 NEC

Questions and answers written by Mark Lamendola, who has worked as a master electrician, electrical inspector, and design engineer. Mark is an IEEE Senior Member, and the Code article author for Codebookcity.com. Since 1996, he has been writing National Electrical Code articles for electrical trade magazines and has an extensive portfolio of hundreds of NEC articles.

Article 400 is the first Article in Chapter 4. But unlike some other 00 Articles, it doesn't lay out its Chapter (4) or serve as an introduction to it. Future revisions of the NEC may start numbering Articles at 1, which is where we actually start numbering things when we count them. The 00 designation would be an explanatory Article for that Chapter. No doubt, this is a long way off. In the meantime, we have this taxonomical error and we just have to live with it.

We begin this 4th installment in this series about Article 400 with two questions on splices.

1. Can you splice flexible cord when installing it?
   

2. Can you ever splice flexible cord?
   
3. What's the purpose of a fitting that's used to connect flexible cord to a device?
   
4. Does it matter what type of flexible cord you use in show windows and showcases as opposed to a similar installation elsewhere in the same room?
   
5. What is the minimum size for a flexible cord to be considered as protected against overcurrent in accordance with 240.5?
