1. A switchboard comprising:
a first compartment into which a circuit breaker having a plurality of breaker terminals is inserted;
a second compartment adjacent to the first compartment and receiving a plurality of bus bars therein;
a plurality of insulating bushings installed on a barrier that is in contact with the first compartment and the second compartment, including a first insulating bushing, a second insulating bushing, and a third insulating bushing,
wherein the second insulating bushing is disposed between the first insulating bushing and the third insulating bushing in a horizontal direction,
wherein each insulating bushing of the plurality of insulating bushings has a contact surface mediating a connection between an associated one breaker terminal of the plurality of breaker terminals and an associated one bus bar of the plurality bus bars, and includes a hole formed in the contact surface having a length defined in the horizontal direction,
wherein each insulating bushing of the plurality of insulating bushings is provided with an associated connecting conductor of a plurality of connecting conductors,
wherein each connecting conductor of the plurality of connecting conductors is connected on a first side to the associated one breaker terminal and on a second side to the associated one bus bar of the plurality of bus bars,
wherein each connecting conductor of the plurality of connecting conductors includes:
a flat plate portion to which the associated one bus bar of the bus bars is coupled; and
an insertion portion of a given width defined in the horizontal direction, the insertion portion protruding in a vertical direction from the flat plate portion,
wherein each insertion portion is inserted in the vertical direction through the hole defined through an associated insulating bushing of the plurality of insulating bushings. and is connected to the associated breaker terminal,
wherein the hole defined in the first insulating bushing has a first length in the horizontal direction that permits the insertion portion inserted therethrough to have a first degree of movement in the horizontal direction,
wherein the hole defined in the third insulating bushing has the first length in the horizontal direction that permits the insertion portion inserted therethrough the first degree of movement in the horizontal direction, and
wherein the hole defined in the second insulating bushing has a second length in the horizontal direction, less than the first length, to permit the insertion portion inserted therethrough a second degree of movement in the horizontal direction that is less than the first degree of movement.
