An integral, unitary cover assembly for covering an electrical connection between first and second electrical cables each having a primary conductor and a neutral conductor includes an inner elastomeric sleeve, an outer elastomeric sleeve and a duct member. The inner sleeve defines a cable passage to receive the electrical connection and the primary conductors of the first and second cables. The outer sleeve surrounds the inner sleeve. The duct member is interposed between the inner and outer sleeves. The duct member defines a neutral conductor passage configured to receive at least one of the neutral conductors therethrough.
