Multi-pole electrical switching apparatus and trip cam assembly therefor

A multi-pole electrical switching apparatus comprising:

• a housing assembly comprising a first housing member and a second housing member coupled to said first housing member;
• and
• a trip cam assembly comprising:
• a first trip cam,
• a second trip cam, and
• an interconnect member coupled to said first trip cam and said second trip cam, said interconnect member extending through said first housing member and said second housing member,
• wherein said first trip cam, said second trip cam, and said interconnect member have a common axis of rotation;
• wherein said interconnect member comprises a first shaft portion, a second shaft portion, and a bearing portion extending from said first shaft portion to said second shaft portion;
• wherein said first shaft portion is coupled to said first trip cam;
• wherein said second shaft portion is coupled to said second trip cam;
• wherein each of said first trip cam and said second trip cam has a thru hole;
• wherein said first shaft portion extends into the thru hole of said first trip cam in order to couple said first shaft portion to said first trip cam;
• and wherein said second shaft portion extends into the thru hole of said second trip cam in order to couple said second shaft portion to said second trip cam.

A multi-pole electrical switching apparatus comprising:

• a housing assembly comprising a first housing member and a second housing member coupled to said first housing member;
• and
• a trip cam assembly comprising:
• a first trip cam,
• a second trip cam, and
