A shorting and grounding arrangement for enclosed, gas-insulated bus bars in which an opening in the enclosure is provided and a pot placed over the opening, the pot containing a contact movably supported therein and having an advance contact, the main contact and advance contact both being adapted to mate with contacts on the bus bar, in which the advance contact is connected through a movable electrical connection with a rigid terminal on the outside wall of the pot to permit larger residual voltages to be shorted through the use of the advance contact and switch gear arranged outside the enclosure.
