Status: historical
Page Count: 19
ICS Code (Fuses and other overcurrent protection devices): 29.120.50
scope:

1.1 These specifications cover the equipment making up the temporary grounding system used on de-energized electric power lines, electric supply stations, and equipment.

1.2 It is common practice for the users of protective grounding equipment to prepare complete instructions and regulations to govern in detail the correct use and maintenance of such equipment.

1.3 The use and maintenance of this equipment are beyond the scope of these specifications.

1.4 These specifications for a system of protective grounding utilizing copper cables are covered in four parts, as follows:

Sections Clamps for Temporary Grounding Jumpers 4 to 16 Ferrules for Temporary Grounding Jumpers 17 to 30 Cables for Temporary Grounding Jumpers 31 to 39 Jumpers (complete assembly of clamps, ferrules, and cable) 40 to 53

1.5 Each of the four parts is an entity of itself if desired, but is listed as a part of the system for completeness and clarification.

1.6 The values stated in Newton-Meter units are to be regarded as the standard. The values in parentheses are the inch-pound units.

1.7 Currents presented in Tables 1 and 3 are based upon cable melting times, as determined from equations by I.M. Onderdonk. See Appendix X3.

1.7.1 Currents presented in Table 5 were determined by use of EPRI Project RP2446 Computer Program RTGC "A Desktop Computer Program for Calculating Rating of Temporary Grounding Cables".

1.7.2 See Appendix X3 for a discussion of these values.

1.8 The following precautionary caveat pertains to the test method portions, Sections 12 and 25 of these specifications: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific precautionary statement, see 32.2.3.
