Three-phase motors, 10 hp to 75 hp, inclusive, must be provided with a current limiting starting device which will limit the starting current to 250 percent of full load current. This will permit the average normal current, normal torque NEMA design “B”, squirrel cage motor of 10 hp or less be started with magnetic full voltage starter. Most squirrel cage induction motors, 10 to 75 hp, inclusive, may be started with an autotransformer type starter connected to give starting voltage of 80 percent of full voltage. Induction motors larger than 75 hp must be of the wound rotor type and shall be started with an increment type starter, which will limit the starting current to 150 percent of full load running current.
