ABSTRACT:
A clamp jaw/lever bypass meter socket includes an insulative base and a plurality of line and load end jaw-type releasable contacts for receiving the blades of a meter. Each of the contacts includes a stationary contact and a movable contact pivotally coupled to the stationary contact. The meter socket also includes a spring biasing said movable contact to be in a clamped position with the stationary contact. The meter socket includes a meter bypass having bypass cams coupled to a manually rotatable shaft. The bypass cams are movable from an operating position whereby the jaw-type contacts one clamped and current flows through a meter and a bypass position in which the bypass cams are electrically shorting the line and load contacts for the same phase for changing or testing a meter without service interruption. Both the stationary and movable contacts are a one-piece construction. The movable contacts include supplemental contact arms so that current is divided between the stationary and movable contacts. Additionally, the insulative base includes recessed cavities formed therein for receiving the jaw-type contact assemblies. Lastly, the bypass cams are permanently engaged with the load end contacts and the bypass mode can be achieved either by engaging the contact assemblies sequentially or simultaneously.
