Current path structure provides a current path between an interrupter assembly and a resistor assembly of a dead tank circuit breaker and includes an electrically conductive fixed support having first and second ends. The first end is fixed to one of the interrupter assembly or the resistor assembly. A substantially hollow, electrically conductive conductor has first and second ends, with a connector at the first end thereof. The connector is removably connected to the other of the interrupter assembly or the resistor assembly. Coupling structure removably couples the conductor with the fixed support such that when coupled, the current path structure is in an operative position electrically connecting the interrupter assembly with the resistor assembly, and when decoupled, the fixed support can be moved into telescoping relation within the conductor defining a collapsed position of the current path structure.
