摘要： A medium or high voltage electrical device includes a housing, a central conductor provided within the housing, and a sacrificial cap configured for mounting on the housing. The sacrificial cap includes an outer housing, an insulated body, and a sacrificial conductor provided within the insulated body, wherein the sacrificial conductor electrically communicates with the central conductor within the housing when the sacrificial cap is mounted on the housing. A voltage test point terminal is provided within the insulated body and accessible via the outer housing of the sacrificial cap to capacitively couple with the sacrificial conductor. The sacrificial cap includes a portion configured to be physically severed to confirm that the electrical connector is de-energized.
