Abstract

Accessories are removably received by a non-contact electrical detector for measuring an electrical characteristic without galvanic contact between the accessory and a non-contact sensor in the non-contact electrical detector. In some embodiments, an accessory is positioned in a gap between first and second extensions of the non-contact electrical detector. In some embodiments, an accessory includes first and second recesses on opposite sides of the accessory. First and second clamp arms of a non-contact electrical detector are inserted within the first and second recesses to removably hold the accessory. An external conductive prong of the accessory is electrically coupled, or is selectively electrically coupleable, with an internal conductive prong of the accessory. The external conductive prong is configured to be inserted into a receptacle of an electrical outlet. In use, the accessory positions the internal conductive prong within a sensing area of the non-contact electrical sensor of the non-contact electrical detector.

First claim

1 . An accessory, comprising:
a non-conductive body selectively positionable in a form factor of a non-contact electrical detector, the form factor configured to removably receive the non-conductive body; an internal conductive prong within the non-conductive body; and an external conductive prong that extends outward from the non-conductive body, wherein the external conductive prong is electrically coupled, or selectively electrically coupleable, with the internal conductive prong, the external conductive prong configured to be inserted into a receptacle of an electrical outlet to electrically couple the external conductive prong to the first receptacle of the electrical outlet.

2 . The accessory of claim 1 , wherein the external conductive prong is a first external conductive prong, the accessory further comprising:
a second external conductive prong that extends outward from the non-conductive body, wherein the second external conductive prong is configured to be inserted into a second receptacle of the electrical outlet to electrically couple the second external conductive prong to the second receptacle of the electrical outlet.

3 . The accessory of claim 2 , wherein the internal conductive prong is a first internal conductive prong, the accessory further comprising a second internal conductive prong within the non-conductive body, wherein:
the first internal conductive prong is electrically coupled to the first external conductive prong; and the second internal conductive prong is electrically coupled to the second external conductive prong.

4 . The accessory of claim 3 , wherein:
the first internal conductive prong is electrically coupled to the first external conductive prong by at least a first electrical wire; and the second internal conductive prong is electrically coupled to the second external conductive prong by at least a second electrical wire.

5 . The accessory of claim 2 , further comprising:
a third external conductive prong extending outward from the non-conductive body, wherein the third external conductive prong is configured to be inserted into a third receptacle of the electrical outlet to electrically couple the third external conductive prong to the third receptacle of the electrical outlet.

6 . The accessory of claim 1 , wherein the external conductive prong is a first external conductive prong, the accessory further comprising:
a second external conductive prong that extends outward from the non-conductive body, wherein the second external conductive prong is selectively electrically coupleable with the internal conductive prong, and the second external conductive prong is electrically isolated from the first external conductive prong; and a switch that selectively electrically couples the first external conductive prong and the second external conductive prong to the internal conductive prong, the switch having:
a first position that electrically couples the first external conductive prong to the internal conductive prong while the second external conductive prong is decoupled from the internal conductive prong; and
a second position that electrically couples the second external conductive prong to internal conductive prong while the first external conductive prong is decoupled from the internal conductive prong.

7 . The accessory of claim 1 , wherein, in use, the non-conductive body of the accessory positions the internal conductive prong within a sensing area of a non-contact electrical sensor of the non-contact electrical detector without galvanically contacting the non-contact electrical sensor.
