ABSTRACT:
A fish tape locator system for use by an electrician comprises a transmitter assembly and a receiver. The system is used by the electrician as an aid in running electric wire through a conduit. The transmitter assembly has a mounting means for attachment to a terminus of the conduit, a switch associated with the mounting means and in alignment with the conduit terminus to be activated by an end of the fish tape as it exits the conduit terminus, and an electronic transmitter coupled to the contact switch to transmit a signal when activated. The receiver worn by or in the general vicinity of the electrician receives the signal from the transmitter and alerts the electrician to the fact the fish tape end has reached the conduit terminus.
