ABSTRACT:
A current sensor for installation on a conductor without breaking the conductor may include an insulating base having a conductor supporting portion and a conductive coil disposed within an outer surface of the insulating base. A magnetically permeable conductor retaining member includes a portion that passes through the coil and is secured to the insulating base. The retaining member defines a conductor receiving aperture portion with the aperture portion being disposed adjacent the conductor supporting portion of the insulating base. With a conductor positioned within the aperture portion, the conductor is secured by the retaining member to the conductor receiving portion of the insulating base and a substantially continuous permeable path is formed by the conductor retaining member about the conductor.
