A stab for use in a plug-in assembly , comprising: a stab piece configured to be rotated into and out of engagement with a bus bar via rotation about a rotational axis , the stab piece comprising: two contact arms of the stab piece configured to engage the bus bar; and a base portion of the stab piece coupled between the two contact arms; and a lug block coupled to the base portion of the stab piece and configured to receive a wire for transmitting power from the bus bar to an electrical component ; wherein the lug block comprises a lug body having an opening for receiving and holding the wire, wherein the base portion of the stab piece is configured to be coupled to a stab shaft for rotating the stab about the rotational axis to transition the stab between engagement and disengagement with the bus bar, characterized in that the lug block is configured to be deformed around the wire to hold the wire when a crimping force is applied to the lug block, wherein the lug block is configured to hold the wire at a position approximately centered on the rotational axis when the lug block is deformed by the crimping force, wherein the crimping force is applied by a crimping mechanism configured to hold the stab while bringing a crimper in contact with the lug block, wherein the lug block comprises a plurality of wings extending from the lug body , wherein the wings are configured to interface with the contact arms to brace the lug between the contact arms when the crimping force is applied to the lug block; wherein the lug block is configured such that the lug body is deformed toward the base portion when the crimping force is applied to the lug block and the lug body is not substantially deformed toward the contact arms when the crimping force is applied to the lug. a stab piece configured to be rotated into and out of engagement with a bus bar via rotation about a rotational axis , the stab piece comprising: two contact arms of the stab piece configured to engage the bus bar; and a base portion of the stab piece coupled between the two contact arms; and a lug block coupled to the base portion of the stab piece and configured to receive a wire for transmitting power from the bus bar to an electrical component ; two contact arms of the stab piece configured to engage the bus bar; and a base portion of the stab piece coupled between the two contact arms; and a lug block coupled to the base portion of the stab piece and configured to receive a wire for transmitting power from the bus bar to an electrical component ; wherein the lug block comprises a lug body having an opening for receiving and holding the wire, wherein the base portion of the stab piece is configured to be coupled to a stab shaft for rotating the stab about the rotational axis to transition the stab between engagement and disengagement with the bus bar, characterized in that the lug block is configured to be deformed around the wire to hold the wire when a crimping force is applied to the lug block, wherein the lug block is configured to hold the wire at a position approximately centered on the rotational axis when the lug block is deformed by the crimping force, wherein the crimping force is applied by a crimping mechanism configured to hold the stab while bringing a crimper in contact with the lug block, wherein the lug block comprises a plurality of wings extending from the lug body , wherein the wings are configured to interface with the contact arms to brace the lug between the contact arms when the crimping force is applied to the lug block; wherein the lug block is configured such that the lug body is deformed toward the base portion when the crimping force is applied to the lug block and the lug body is not substantially deformed toward the contact arms when the crimping force is applied to the lug. <EOS>
