Conductor identifying probe and voltage supply device

Claim 1

A portable probe-type conductor identifying and voltage supply device for identifying individual conductors in a plural conductor group extending through a conduit system, cable or the like, comprising a probe having a contact tip for engaging the individual conductors at one end of the plural conductor group and a grounding wire lead and terminal clamp device extending therefrom for releasable attachment to electrical ground at said one end, the probe further including a pair of light emitting diodes for emitting a first color and a second color respectively connected in reverse polarity parallel circuit arrangement between said contact tip and said grounding wire lead; a portable voltage supply unit including a casing housing batteries and having a plurality of manual switches and a like number of respectively associated connector leads with terminal clamp devices thereon and voltage control circuit means therefor, a grounding wire lead and clamp device for said voltage supply unit for attachment to electrical ground at a second end of the plural conductor group opposite said one end, said voltage control circuit means including means responsive to first and second pairs of said switches respectively to apply proper polarity voltages to their associated connector leads when connected at said second end to conductors of said group and when the probe tip engages such conductors to activate the diodes to emit their respective colors as steady light for said first pair of switches and as flashing light for said second pair of switches for identification of the conductors associated with said connector leads by such colors and light character emitted by the probe.
