Abstract
An electrical device includes a body, an electrical contact having a first end for electrically coupling to an electrical apparatus and a second end within the body, and a conductor electrically coupled to the second end of the electrical contact. The electrical device also includes an access region defining a cavity and a surge arrester that electrically couples to the conductor through the access region. The cavity provides access to an interior of the electrical device. The access region may include an insulating projection extending from an insulating body of the electrical device and a conductive cover surrounding the insulating projection. The insulating projection defines the cavity. The conductive cover is electrically isolated relative to a conductive shell that surrounds the insulating body.
