The side interfaces of the electrical connector can be designed to accommodate different high voltage connectors.

Abstract: We disclose a method for securing an infrared transmissive polymer to integrated panels, deadfronts, or transition plates, thus providing a reinforced polymer window through which the thermographer can scan an energized unit without being directly exposed to contact with internal components or having to remove said panels, deadfronts, or transition plates. We also disclose a device for securing the polymer consisting of a retention frame with half shear retainers that keep the polymer locked in place.

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.
