Abstract:
An electrical circuit tester for temporary connection across a group of conductors to determine whether AC power is present, the tester comprising:a housing; the electrical prong assembly, integral to the housing, having a first electrical prong, a second electrical prong, and a third electrical prong such that the first electrical prong is associated with the hot wire of a single phase electrical circuit, the second electrical prong is associated with the neutral wire of a single phase electrical circuit, and the third electrical prong is associated with the ground wire of a single phase electrical circuit; an electrically-activated audible signal means, integral to the housing, having a first electrical connection and a second electrical connection such that the audible signal means is activated when electric current flows between the first electrical connection and the second electrical connection; a first switching means, integral to the housing, having a first switch first position and a first switch second position; and a second switching means, integral to the housing, having a second switch first position and a second switch second position, such that when the second switch is in the second switch first position and the first switch is in the first switch first position, the first electrical connection of the audible signal means is connected to the second electrical prong, and the second electrical connection of the audible signal means is connected to the first electrical prong, and when the second switch is in the second switch first position and the first switch is in the first switch second position, the first electrical connection of the audible signal means is connected to the third electrical prong, and the second electrical connection of the audible signal means is connected to the first electrical prong, and when the second switch is in the second switch second position and the first switch is in the first switch second position, the first electrical connection of the audible signal means is connected to the third electrical prong, and the second electrical connection of the audible signal means is connected to the second electrical prong, thereby providing a test for reverse polarity.
