Abstract
A non-fusible switch assembly including a line base assembly is disclosed. Line base assembly includes a load bus connector assembly with single-piece lug body, first and second load lugs formed in the lug body, and load-side sliding nuts slidably received in first and second load-side slide features, and load-side stationary contacts positioned directly underneath of the first and second load lugs within a projected footprint of the lug body. Line base assemblies, load lug connector assemblies and methods of operating a line base assembly are provided, as are other aspects.
Claims12
A line base assembly, comprising:
- a base;
- a line bus connector assembly coupled to the base, the line bus connector assembly including:
- a connector body including a first body portion and a second body portion extending from the first body portion and being thinner than first body portion, wherein the connector body is a single piece, first and second line lugs formed in the first body portion, and first and second line slide features formed in the connector body,
- first and second line-side sliding nuts configured to be received in the first and second line slide features, and
- line-side stationary contacts coupled to the second body portion;
- and
- a load bus connector assembly coupled to the base, the load bus connector assembly including:
- a lug body including a front side, a back side, and an underside, wherein the lug body is a single piece, first and second load lugs formed in the lug body, and first and second load slide features formed in the lug body,
- first and second load-side sliding nuts configured to be received in the first and second load slide features, and
- load-side stationary contacts attached to, and extending downward from, the underside of the lug body, and wherein the load-side stationary contacts are positioned directly underneath of the first and second load lugs within a projected footprint of the lug body.
A non-fusible switch assembly, comprising:
- a line base assembly including:
- a base;
- a line bus connector assembly coupled to the base, wherein the line bus connector assembly comprises:
- a connector body including a first body portion and a second body portion extending from the first body portion and being thinner than first body portion, wherein the lug body is a single piece, first and second line lugs formed in the first body portion, and first and second line-side slide features formed in the connector body,
- first and second line-side sliding nuts configured to be received in the first and second
- line-side slide features, and
- line-side stationary contacts coupled to the second body portion;
- a load bus connector assembly coupled to the base, the load bus connector assembly including:
- a lug body including a front side, a back side, and an underside, wherein the lug body is a single piece, first and second load lugs formed in the lug body, and first and second load slide features formed in the lug body,
- first and second load-side sliding nuts configured to be received in the first and second load slide features, and
- load-side stationary contacts attached to, and extending downward from, the underside of the lug body, and wherein the load-side stationary contacts are positioned directly underneath of the first and second load lugs within a projected footprint of the lug body;
- and
- a rotor assembly including blades adapted to electrically couple to line-side stationary contacts and the load-side stationary contacts.
A line bus connector assembly for use with a base, the line bus connector assembly including:
- a connector body including a first body portion and a second body portion extending from the first body portion and being thinner than first body portion, wherein the connector body is a single piece, first and second line lugs formed in the first body portion, and first and second line slide features formed in the connector body,
- first and second line-side sliding nuts configured to be received in the first and second line slide features, and
- line-side stationary contacts coupled to the second body portion.
