Well, at first blush that seems to provide a firm answer to one hotly debated topic:
Electric vehicle supply equipment rated at 125 volts, single phase, 15 or 20 amperes or part of a system identified and listed as suitable for the purpose and meeting the requirements of 625.18, 625.19, and 625.29 shall be permitted to be cord-and-plug-connected. All other electric vehicle supply equipment shall be permanently connected and fastened in place.
But that second "or" in the first sentence is bothersome. Subsections 18 and 19 appear to say that only 125v, 15A or 20A can be plug connected, but I didn't see anything about that in subsection 29. Besides, what is the point of identifying those three subsections if they don't enlarge the class of EVSEs allowed to be plug connected?
