raceways, or cables are subject to movement by settlement
or frost, direct-buried conductors, raceways, or cables shall
be arranged so as to prevent damage to the enclosed conductors
or to equipment connected to the raceways.
FPN: This section recognizes ?S? loops in underground
direct burial to raceway transitions, expansion fittings in
raceway risers to fixed equipment, and, generally, the provision
of flexible connections to equipment subject to
settlement or frost heaves.
