Abstract:
Various electrical apparatuses which include a current dampening device are disclosed. In one embodiment, an electrical apparatus is provided which includes a motor and a switch having an “on” position and an “off” position to control the operation of the motor. A current dampening device is connected in parallel with the motor downstream from the switch to dampen transient current. In another embodiment a ground fault circuit interrupter (GFCI) is electrically connected to the motor upstream from the switch.
