Abstract
A current sensing device includes a housing with a head adapted for releasably holding a wire of an electrical circuit without breaking the electrical circuit. The head has one or more current sensors configured to sense direct current in the wire without breaking the electrical circuit. The housing includes an alarm to indicate if the current sensing device senses a current in the electrical wire above a predefined threshold current. The head has a clip base and clip member that form an internal channel to closely receive the electrical wire and to releasably hold the electrical wire for testing. In some embodiments, the head has an internal channel that intersects the outer surface of the head and forms a longitudinal opening to allow insertion of the wire into the internal channel. The current sensing device has a processor programed to calibrate the current sensing device to compensate for electrical noise.
