30 CFR § 75.812
Movement of high-voltage power centers and portable transformers; permit.
[STATUTORY PROVISIONS]
Power centers and portable transformers shall be deenergized before they are
moved from one location to another, except that, when equipment powered by
sources other than such centers or transformers is not available, the
Secretary may permit such centers and transformers to be moved while
energized, if he determines that another equivalent or greater hazard may
otherwise be created, and if they are moved under the supervision of a
qualified person, and if such centers and transformers are examined prior to
such movement by such person and found to be grounded by methods approved by
an authorized representative of the Secretary and otherwise protected from
hazards to the miner. A record shall be kept of such examinations.
High-voltage cables, other than trailing cables, shall not be moved or
handled at any time while energized, except that, when such centers and
transformers are moved while energized as permitted under this section,
energized high-voltage cables attached to such centers and transformers may
be moved only by a qualified person and the operator of such mine shall
require that such person wear approved and tested insulated wireman's
gloves.
