Abstract
An integral, unitary pre-expanded cover assembly unit for covering an electrical connection between first and second electrical cables each having a primary conductor and a 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 is neutral conductor includes a cover assembly and a removable holdout. The cover assembly includes an elastomeric inner sleeve, an elastomeric outer sleeve, and a duct. The inner interposed radially between the inner and outer sleeves. The duct defines a duct passage configured to receive at least one of the neutral conductors therethrough. The holdout is mounted within the inner sleeve. The holdout is operative to temporarily maintain the inner sleeve in an expanded state and the outer sleeve in an expanded state. The duct is flexible. The duct is operative to resist radial collapse of the duct and to bend radially inwardly as the holdout is axially removed from the inner sleeve.
