Busway stab assemblies and related systems and methods

A busway system comprising:

• a busway section comprising:
• a busway housing defining a longitudinal axis, the busway housing comprising first and second opposite side portions;
• a first insulator held in the first side portion of the busway housing, the first insulator holding one or more bus bar conductors;
• a second insulator held in the second side portion of the housing, the second insulator holding one or more bus bar conductors;
• and
• a plug-in device comprising:
• a stab base housing having first and second opposite sides;
• one or more stab conductors extending out of and away from the stab base housing at the first side of the stab base housing;
• one or more stab conductors extending out of and away from the stab base housing at the second side of the stab base housing;
• wherein the stab base housing is configured to be received through an opening at a bottom portion of the busway housing and positioned in a first position with each stab conductor extending away from the stab base housing in a direction substantially parallel to the longitudinal axis of the busway housing;
• wherein the stab base housing is configured to be rotated from the first position to a second position with each stab conductor extending away from the stab base housing in a direction substantially perpendicular to the longitudinal axis of the busway housing;
• wherein each stab base conductor is electrically connected to one of the bus bar conductors in the second position;
• wherein the stab base housing comprises an alignment feature configured to allow rotation of the stab base housing from the first position to the second position in only one rotational direction;
• wherein:
• the stab base housing includes an upper portion and a lower portion;
• the plug-in device includes a ground conductor includes including a convex upper surface that extends upwardly from the upper portion of the stab base housing;
• and
• the ground conductor is resilient and configured to translate up and down relative to the stab base housing in response to contact with a top wall of the busway housing.

A method comprising:

• providing a busway section comprising:
• a busway housing defining a longitudinal axis, the busway housing comprising first and second opposite side portions;
• a first insulator held in the first side portion of the busway housing, the first insulator holding one or more bus bar conductors;
• a second insulator held in the second side portion of the housing, the second insulator holding one or more bus bar conductors;
• and
• providing a plug-in device comprising:
• a stab base housing having first and second opposite sides;
• one or more stab conductors extending out of and away from the stab base housing at the first side of the stab base housing;
• one or more stab conductors extending out of and away from the stab base housing at the second side of the stab base housing;
• and
• a ground conductor extending upwardly from an upper portion of the stab base housing;
• receiving the stab base housing through an opening in a bottom portion of the busway housing in a first position with each stab conductor extending away from the stab base housing in a direction substantially parallel to the longitudinal axis of the busway housing and with the ground conductor contacting a top wall of the busway housing;
• and
• rotating the stab base housing from the first position to a second position with each stab conductor extending away from the stab base housing in a direction substantially perpendicular to the longitudinal axis of the busway housing and with the ground conductor contacting the top wall of the busway housing;
• wherein the stab base housing comprises an alignment feature configured to allow rotation of the stab base housing from the first position to the second position in only one rotational direction;
• wherein the ground conductor is resilient and configured to translate up and down relative to the stab base housing in response to contact with the top wall of the busway housing.
