Abstract
A portable device for field testing watthour meters including a socket with one or more connectors configured to engage a watthour meter blade is disclosed. The connectors may include a pair of wire forms so oriented that the connector can connect to a watthour meter blade oriented in either of two orientations 90° apart from each other by resiliently deflecting portions of the wire forms. The connectors may include a jaw socket cup, a torsion clip in the jaw socket cup for contacting a watthour meter blade when the watthour meter blade is inserted into the jaw socket cup. The torsion clip includes a first surface and a pair of facing surfaces connected to, and extending away from, the first surface that define a channel sized to receive the watthour meter blade.
