Plug-in contact structure for panelboard

Claim 1

An assembly including main conductor means for a panelboard and first and second plug-in type circuit breaker modules connected to said assembly, said first module being of a first width and said second module being of a second width approximately two times the first width; said main conductor means including first and second bus bars; a plurality of first contact sections formed integrally with said first bus bar and a plurality of second contact sections formed integrally with said second bus bar; each of said first and second contact sections including first and second generally planar parallel contact blades spaced by approximately said first width; said blades of said plurality of said first and second contact sections being arranged in a row with the blades being in spaced parallel planes generally perpendicular to the length of said row; said first and second contact sections being interleaved; said first blade of each of said first contact sections being spaced from said second blade of a different one of said contact sections by approximately said first width; each of said blades being constructed to constitute a male plug-in contact to be engaged by a female plug-in contact of a circuit breaker module of said first width; each of said contact sections being constructed so that the first and second blades thereof cooperate to constitute a female contact to receive a male plug-in contact of a circuit breaker module of said second width; said first module including a female plug-in contact having jaws in direct engagement with opposite sides of a first of said blades; said second module including a male plug-in contact having first and second sides in direct engagement with the respective first and second blades of one of said contact sections.
