On October 23, 2018, I posted a picture of this illuminated pumpkin and wrote that the extension cord could not be used since Article 400.8 (3) of NFPA 70-2011 says flexible cords could not be used as a substitute for fixed wiring. But just recently, a reader asked why this illuminated pumpkin would not qualify for Article 590.3(B) that permits extension cords on holiday decorations for up to 90-days.
After reviewing NFPA 70-2011, I discovered I was incorrect in my original posting and thanked the reader for bringing this to my attention. I then made changes to the original posting to ensure the correct code interpretation was stated.
To be sure, NFPA 70-2011, Article 590.3(B), says extension cords are permitted to be used for holiday decorations up to 90-days. But Article 590.2(A) does say all other requirements of the code would have to be met. implying the extension cord would have to be listed by a national listing agency (i.e. UL). Also, Article 590.2(B) says temporary wiring is acceptable if it is approved based on the conditions of use. So, you would not be able to abuse the concept of an extension cord used on holiday decorations.
This also means that individual organizations could have policies specific to their staff that limit or prohibit the use of extension cords on holiday decorations beyond what NFPA 70-2011 provides.
I apologize for this error, and appreciate the reader for bringing this to my attention.
