(2) The raceway extends directly above the enclosure and does not penetrate a structural ceiling;

(3) A fitting is provided on each end of the raceway to protect the cable from abrasion, and the fittings remain accessible after installation;

(4) The raceway is sealed or plugged at the outer end using approved means so as to prevent access to the enclosure through the raceway;

(5) The cable sheath is continuous through the raceway and extends into the enclosure not less than 0.25 in. (6.35 mm) beyond the fitting;

(6) The raceway is fastened at its outer end and at other points as necessary; and
