Abstract
The present disclosure is generally directed to a GF detection circuit for use in blenders and other appliances that can detect current leak/GF events and selectively decouple/de-energize components of the blender that could bring a user in contact with dangerous electrical currents. Preferably, a blender consistent with the present disclosure includes at least one ground plane, e.g., in the form of conductive material/sections, disposed on the blender and/or blender jar that act as an input to a GF detection circuit that is at least partially implemented within the base of the blender.
