ABSTRACT:
A pair of identical covers house and insulate two split cores of the type used to submonitor current flow into a breaker box. The covers keep the cores in correct alignment and identify the proper orientation of a pick-up transformer that is coupled to the cores. The covers are molded from a non-conducting plastic and have an integral locking mechanism utilizing a living hinge. Integral spring tabs and integral alignment tabs hold the split cores securely next to one another. Arrow markings on the split covers are matched with an arrow marking on the pick-up transformer which is placed around the assembled covers to form a current sensing unit. The face of the current sensing unit with the arrows is directed towards the current source. Electric current can then be monitored using a digital watt/hour meter connected to the current sensing unit. The locking mechanism of the covers enables the current sensing unit to be easily removable for use at other locations.
