Claim:
A system for mounting and retaining an electronic device in a panel having an opening, the system comprising: a power monitoring device for monitoring characteristics of the power transmitted through one or more power lines, the power monitoring device including a face portion and a body portion; and an apparatus coupled to the power monitoring device and adapted to secure the power monitoring device within the panel opening by engaging at least one surface of the panel, wherein the apparatus comprises interlocking components that rotate into a locked position to secure the power monitoring device within the panel opening, said interlocking components including (i) an inner component including a circular hub having a toothed disk and (ii) an outer component including a circular member having a locking flex member and a cam element, the outer component being adapted to mate with the inner component and to rotate around the circular hub when the inner and outer components are attached to the body portion of the power monitoring device that is inserted into the opening in the panel, and wherein as the outer component is rotated, the toothed disk locks against the locking flex member and the cam element exerts pressure against the at least one surface of the panel to hold the power monitoring device within the panel opening.
