Using the defacto info that a receptacle 5 1/2' high or over does not count for resi spacing, and the supposition that utilization equipment cords are 6' from mfg, the 61/2' height would raise concerns. An invitation for extension cords perhaps?
Basically, my point is place a floor lamp with a 6' cord on the balcony, and you cannot plug it in without an extension cord.
Make any logical sense??
