Earthing equipment for a switchgear is comprised of a movable carrying cart, a switch portion, a manipulating portion, and a voltage detecting device. The earthing equipment is provided with: an upper conductor connected to any one of the movable electrode and the stationary electrode; a lower conductor connected to the other of the movable electrode and the stationary electrode, an earthing wire connecting the lower conductor to a terminal used for earthing of the switchgear; and an adaptor conductor being selectively connected to either a disconnection portion at a bus bar side or a disconnection portion at a cable side of the switchgear and is permitted to be selectively replaced on either upper or lower face of the upper conductor.
