34 Pa. Code § 39.417 - Handling switchboard equipment
(a) Ungrounded metal parts of devices on
switchboards shall be handled as if operating at the highest voltage to which
any portion of the equipment on the same switchboard panel is subject, unless
the parts are known, by test or otherwise, to be free from such
voltage.
(b) When cable plug
connectors are used, one end shall not remain hanging loose while the other end
is connected to a live terminal. In handling instrument circuits, the secondary
of a current transformer should never be opened when it is alive.
