Abstract: A lay-in lug has two spaced apart and substantially parallel lug walls. A nut plate is supported between the first lug wall and the second lug wall. A plate retainer exerts force on a lug wall and restricts the plate from moving in a direction substantially parallel to the first and second lug walls. The plate retainer has a flexible retaining base and a pair of retaining legs extending from the retaining base. Snap protrusions extend from each of the retaining legs and are formed to interlock with a portion of the wall of the lay-in lug and restrict movement the nut plate. The plate retainer either snaps around the edge of the lug wall or along the wall's length. It may also clip around the nut plate and prevents its movement in a direction along the inner surfaces of the lug walls.

Abstract: A field rephaseable metering device is provided including at least three distribution buses including two side buses and a center bus, the center bus having a vertical center line. At least one meter socket is provided having a vertical center line offset from the vertical center line of said center bus, each meter socket including a first line terminal and a second line terminal. At least two line straps are provided, each having a first end configured for connecting with one of the first or second line terminals, and a second elongate end configured to be selectively connectable to one of the side buses associated with its line terminal or the center bus. When each line strap is positioned to connect one of the line terminals with one of the distribution buses, a longitudinal axis of each line strap is substantially perpendicular to a longitudinal axis of each distribution bus.

Abstract: The present invention relates generally to multi-position metering apparatus. More particularly, the invention encompasses a wire distributed 5th jaw system for multi-position metering. The present invention is also directed to a novel multi-position metering device with multiple optional 5th terminals. The invention further provides a way to use a single wire as potential to connect all 5th terminals in a multi-position metering device. A single wire with insulation, one end of which is connected to line neutral, is laid out to pass by all meter sockets through designated channel on each meter socket base. The single wire is then stripped on a specified area when it passes on each meter socket for electrical connection to a 5th terminal through a potential.

Abstract: The invention provides a meter socket assembly for a watt-hour meter with removable and changeable meter jaws. The meter socket assembly comprises a meter base, at least one meter jaw assembly with two optional 5th terminal provisions. The assemblies are snapped on to the meter base and locked into the meter base. Any meter jaw assembly in the meter socket device is able to be removed or changed by simply loosening a connection nut and then releasing the meter jaw assembly by pressing a cross locking tab. The meter base, mounted to enclosure of a meter socket device or a meter socket module, is also changeable. The meter socket device is suitable for a meter socket with line and load busing connections, especially modular metering devices.
