Except as required or permitted elsewhere in this standard, live parts of
electric equipment operating at 50 volts or more shall be guarded against accidental
contact by approved cabinets, enclosures, or by:
- Location in a room, vault, or similar enclosure only accessible to qualified persons
- Suitable permanent, substantial partitions or screens so arranged that only qualified
persons will have access to the space within reach of the live parts and that any openings
shall be so sized and located to prevent accidental contact with the live parts or to
bring conducting objects into contact with them
- Location on a suitable balcony, gallery, or platform
- Elevation of 8 feet or more above the floor or other working surface.
In locations where electric equipment would be exposed to
physical damage, enclosures or guards shall be so arranged and of such strength as to
prevent such damage.
The purpose of guarding equipment is to protect any person, not just qualified
electricians, against accidental electrical equipment contact. |
