Abstract
An electric current sensor assembly and method. A housing containing a Hall effect device is provided with at least one curved, concave surface for placement against a wire carrying a current. The housing is attached to the wire by a strap that fastens around the housing and the wire and fits in grooves in the housing. When the assembly is installed, the Hall effect device is positioned so that the magnetic field produced by current in the wire passes through the Hall effect device and produces an electric signal proportional to the amplitude of the current in the wire. A set screw is movably mounted in the housing adjacent the Hall effect device to adjust the sensitivity of the current sensor assembly.
