Interested in your thoughts on my assessment of the following methods of wiring the input of a retractable cord reel to power a floor mounted jib crane:
1. Reel input cord and plug connected to a receptacle outlet. (Acceptable, consider the same a retractable extension cord)
2. Reel input hardwired to a disconnect switch using NEC Chapter 3 Wiring Methods. (Acceptable, consider the same as a retractable pendent)
3. Reel input hardwired to a disconnect switch or junction box using flexible cord. (Not acceptable, violates Article 400.12(1))
Follow on question: Article 410.10(5) permits flexible cord to be used for wiring of cranes and hoists. Would this permit the input of the retractable cord reel powering the jib crane to be wired with flexible cord rather than Chapter 3 wiring methods, contrary to my thought in 3 above?
