ABSTRACT:
A housing and clamp assembly for mounting a circuit condition monitoring device on a monitored electrical cable includes a body member for housing device circuitry, a first relatively non-resilient clamp arm, and a second relatively resilient clamp arm. The clamp arms are biased closed around the conductor without pre-configuration of the clamp arms by parallel-spaced helical springs, which also serve to hold the cable against an indexing surface on the first clamp arm to minimize the effect of cable diameter on the spacing between the cable and the condition monitoring device and hence the calibration of the monitoring device.
