Abstract: A connector device includes a device body and a pin assembly. The connector device includes a bushing portion with a conductive bus having a first bore, a conductive housing with a second bore that is axially aligned with the first bore, an internal chamber separating the first bore and the second bore, and a gelatinous silicone material enclosed within the internal chamber. The pin assembly includes a non-conductive tip and a conductive pin secured to the non-conductive tip. The pin assembly is configured to move axially, within the first and second bores, between a closed position that provides an electrical connection between the conductive bus and the conductive housing and an open position that provides no electrical connection between the conductive bus and the conductive housing. The gelatinous silicone material inhibits voltage arcing across a surface of the non-conductive tip when the pin assembly is in the open position.

Abstract: A mechanical grounding connector is provided for connecting at least two conductors. The connector is comprised of a first, second and third body section which have channels that allow for installation of conductors between each of the body sections. The channels of each body section lie at 90 degree angles such that conductors can be installed in a parallel or transverse arrangement. Bolts are used to hold together the first, second and third body sections of the connector and allow the body sections to be separated from one another by loosening the bolts to install conductors, without the need to completely remove the bolts from the connector.

Abstract: An electrical disconnect for a utility service that has an internal reversible insulator and a separable power connector. In one position, the insulator may allow the flow of electricity through the separable power connector, but, in a second position, the insulator prevents the flow of electricity through the separable power connector. Because the electrical disconnect is located away from the customer's premises, it is difficult for the customer to reconnect his own power.
