An enclosure for a network protector in an electrical distribution network includes a cabinet body that defines an interior region that accepts the network protector. The cabinet body three electrodes sealed with and electrically isolated from the cabinet body and each other, which extend through the cabinet body to establish electrical connection between corresponding terminals of the network protector and the electrical distribution network. First and second doors are pivotably connected to opposing sides of the cabinet body and have respective contact surfaces to seal against the cabinet body. A first gasket is disposed along a distal edge surface of the first door, and a second gasket is disposed along a distal edge surface of the second door. At least a portion of the first gasket and the second gasket have conformal shapes that sealingly mate with each other when the first and second doors are in a closed position.
