A bushing structure for switchgear includes first and second separate support structures each having surfaces defining at least one opening. The support structures are coupled together so that the openings define a passage through the bushing structure and so that a slot is defined between the first and second support structures, surrounding the passage. A bushing is disposed in the passage and has a body, a bus receiving member, and a compression structure. The bus receiving member has an opening there-through sized to receive a bus bar. When the first and second support structures are coupled together with the bushing in the passage, the compression structure is disposed in the slot, sandwiched between the first and second support structures so that they exert pressure on the compression structure.

1. A bushing structure for mounting to a switchgear frame and for supporting bus bars, the bushing structure comprising: first and second separate support structures each having surfaces defining at least one opening, the support structures being coupled together so that the openings cooperate to define at least one passage through the bushing structure and so that a slot is defined between the first and second support structures, surrounding the passage, anda bushing constructed and arranged to be disposed in the passage, the bushing having a body, at least one bus receiving member, and a compression structure surrounding the at least one bus receiving member, the bus receiving member having an opening there-through sized to receive a bus bar,wherein, when the first and second support structures are coupled together with the bushing in the passage, the compression structure is disposed in the slot, sandwiched between the first and second support structures so that the first and second support structures exert pressure on the compression structure. 2. The bushing structure of claim 1, wherein the bushing includes a pair of bush receiving members that are provided in spaced relation and isolated from each other, each bus receiving member having an opening there-through sized to receive a bus bar, and wherein the compression surrounds the pair of bus receiving members. 3. The bushing structure of claim 1, wherein the compression structure comprises a continuous, raised rib provided each of opposing sides of the body. 4. The bushing structure of claim 1, further comprising a bus bar disposed in the opening in the at least one bus receiving member. 5. The bushing structure of claim 1, wherein first and second separate support structures each having surfaces defining three separate passages, with a bushing being disposed in each passage. 6. The bushing structure of claim 1, wherein the bushing is made of rubber. 7. The bushing structure of claim 1, wherein the bushing is made of ethylene propylene diene monomer (EPDM). 8. The bushing structure of claim 1, wherein the second support structure is a mirror image of the first support structure. 9. The bushing structure of claim 1, wherein the at least one bus receiving member extends from opposing sides of the body. 10. A method of supporting bus bars for a switchgear, the method comprising: providing first and second separate support structures each having surfaces defining at least one opening, inserting a bus bar into an opening of the first support structure,providing a bushing having a body, at least one bus receiving member, and a compression structure surrounding the bus receiving member, the bus receiving member having an opening there-through,inserting an end of the bus bar into the opening in the bus receiving member,inserting the end of the bus bar into an opening in the second support structure,coupling the support structures together so that the openings in the support structures cooperate to define at least one passage, with the bus bar extending through the passage, and so that a slot is defined between the first and second support structures that surrounds the passage, with the compression structure being disposed in the slot, sandwiched between the first and second support structures so that the first and second support structures exert pressure on the compression structure. 11. The method of claim 10, wherein the step of providing the bushing provides the bushing of rubber. 12. The method of claim 10, wherein the step of providing the bushing provides the bushing of ethylene propylene diene monomer (EPDM). 13. The method of claim 10, wherein the step of providing the first and second support structures provides the second support structure as a mirror image of the first support structure. 14. The method of claim 10, wherein the step of coupling the first and second support structures includes using fasteners. 15. The method of claim 10, further comprising after the coupling step, mounting the coupled first and second support structures to a wall of a switchgear.
