Description:This British Standard gives guidance on the methods that may be adopeted to earth an electrical system for the purpose of limiting the potential (with respect to the general mass of the earth) of current-carrying conductors forming part of the system, and non-current-carrying metalwork associated with equipment, apparatus, and appliances connected to the system.
BS 7430 applies only to land-based installations; it does not apply to ships, aircraft or offshore installations, nor does it deal with the earthing of medical equipment (see BS 5724) or the special problems encountered with solid state electronic components and equipment due to their sensitivity to static electricity.
This standard does not address electromagnetic compatibility requirements for earthing, nor does it give recommendations for functional earthing.
