Abstract

A watthour meter socket adapter 310 includes a plurality of current jaw contacts 290 and potential jaw contacts 10 mounted between front and rear housings 314, 312, with each jaw contact 290, 10 surrounding by a receptacle 422, 70 in the front housing 314. An aperture in each receptacle 422, 70 allows insertion of a meter blade terminal into the jaw contact. An electrical conductor extends from each jaw contact 290, 10 to an individual terminal 102 mounted in a terminal portion of the front and rear housings 314, 312. Apertures in the front housing 314 allow insertion of a tool into engagement with a fastener 112 carried on each terminal 290, 10 for fixedly joining a terminal clip 116 mounted a conductor 132 extending from the jaw contacts to an external conductor 138 inserted through openings in the bottom of the front and rear housings. The potential jaw contacts 10 are in the form of three linearly spaced fingers 12, 14, 20, with two of the fingers 12, 14 being spaced apart by an intermediate third finger 20, and projecting to one side of the jaw contact, opposite from the outer end of the intermediate, third finger to define a slot for receiving a potential meter blade terminal. A flange 30 and a tab 42 are formed on each potential jaw contact 10 for attaching a plurality of external conductors 44, 41 to each potential jaw contact 10. Another set of apertures formed in the front housing 314 allow access of at least a pair of electrically connected shorting pins 164 coupled to two terminal clips 116 and aligned with the apertures to electrically connect a pair of electrical conductors, jaw contacts and terminals in the housing.
