The NEC does require GFCI receptacles in garages and hangers, but not on process, industrial and manufacturing floors because the risk of electrical shock is much higher in the former locations.Garages and hangers are typically used for storage and repair of vehicles, which can involve the use of power tools and other electrical equipment. These activities can create a risk of electrical shock if the equipment is not properly grounded or if there is a fault in the electrical system.Process, industrial and manufacturing floors, on the other hand, are typically used for the production of goods and materials. The equipment used in these locations is typically fixed in place and is not likely to be moved or bumped, which reduces the risk of electrical shock. Flag for review
