§ 39.282. Grounding.
(a) The permanent grounding of frames of portable devices, especially in connection with voltage above 150 to ground and for any voltage when the devices are used within eight feet of the floor in locations such as bathrooms, laundries, and the like, where persons may easily touch ground surfaces at the same time as the device, should be used as a safety measure, if this is practicable and suitable means are available, but cannot, of course, be reasonably required unless such means are available. Such grounding may be obtained by the use of a three wire portable cord with the portable device, one wire being used for the ground conductor and the connectors being properly designed so that wrong connections are not made by the user of the device.
(b) In lieu of grounding the external metal parts of portable lamp sockets if suitable means, as described in subsection (a), are not readily available, sockets and lamp guards or other similar devices of suitable insulating material may be used, and should be used in the hazardous locations listed previously.
