A touch-safe bus connection device includes a bus extension (160, 260, 360), a non-conductive housing (110, 210, 310), a moveable electrical contact (150, 250, 350) and a moveable non-conductive cover (140, 240, 340). The contact is arranged in the housing, and is moved to connect or disconnect the extension and a stab of an electrical panel across a gap (192, 292, 392). The cover is concurrently and automatically moved to uncover or cover an opening (116, 216, 316) of the housing to allow or restrict, respectively, access to the extension. The contact and cover are concurrently and automatically moveable between a position at which the contact bridges the gap to connect the extension and the stab and the opening of the housing is covered by the cover, and another position at which the extension and the stab are disconnected across the gap and the opening of the housing is uncovered. |

1. A touch-safe bus connection device for an electrical panel, comprising:
a bus extension having a first end to be arranged at a gap from a stab of the electrical panel, and a second end for connecting to a terminal of an electrical device; a non-conductive housing having the bus extension arranged therein, the housing including a first opening for allowing connection of the first end of the bus extension to the stab and a second opening for allowing connection of the terminal of the electrical device to the second end of the bus extension; a moveable electrical contact, arranged in the housing, for connecting or disconnecting the first end of the bus extension and the stab of the electrical panel across the gap; and a moveable non-conductive cover, concurrently movable with the moveable electrical contact, for uncovering or covering the second opening of the housing to allow or restrict, respectively, access to the second end of the bus extension, the electrical contact and the cover being moveable between (1) a first position at which the electrical contact bridges the gap to connect the first end of the bus extension and the stab and the second opening of the housing is covered by the cover, and (2) a second position at which the first end of the bus extension and the stab are disconnected from each other across the gap and the second opening of the housing is uncovered. |
