620.21 Wiring Methods. Conductors and optical fibers located in hoistways, in escalator and moving walk wellways, in platform lifts, stairway chairlift runways, machinery spaces, control spaces, in or on cars, in machine rooms and control rooms, not including the traveling cables connecting the car or counterweight and hoistway wiring, shall be installed in rigid metal conduit, intermediate metal conduit, electrical metallic tubing, rigid nonmetallic conduit, or wireways, or shall be Type MC, MI, or AC cable unless otherwise permitted in 620.21(A) through (C).
Exception: Listed cord and plug connected equipment may be placed in in control spaces, in or on cars, in machine rooms and control rooms. [ROP 12?28]
5 Statement of Problem and Substantiation.
The new exception is the size of a barn door. It would allow microwaves, curling irons, and blenders in elevator shafts with standard cordage. It is completely out of line with the almost 3 pages of requirements for wiring in 620.21.
