A high voltage conductor assembly includes a high voltage conductor having a conductor fastening end with an opening receiving a fastener to connect the conductor fastening end to a power terminal of a high voltage electrical device. The high voltage conductor assembly includes a conductor retainer having a dielectric body with a retainer cavity configured to receive a portion of the high voltage conductor. The conductor retainer includes a retainer flange configured to be received in a retainer pocket of a housing of the high voltage electrical device to position the conductor retainer relative to the high voltage electrical device. The retainer flange includes a latch element latchably coupled to the housing of the high voltage electrical device. The conductor retainer independently holds a position of the conductor fastening end of the high voltage conductor relative to the power terminal for contact free assembly of the high voltage conductor to the power terminal.
