Oh YES! 90% of the approx 6,000 sq/ft building is done this way.
Aside from the obvious disregard for any electrical code by the moron that did the wiring, what really boggles my mind is how someone can purchase a property like this. Complete lack of public safety on the part of the seller, bank & township that let someone purchase this building "as is". I mean, come-on... I can't sell my house unless I make sure I have GFCI outlets where required ...but this is ok???
