TIA 942 Generator Ground Fault_ 83 ft

TIA 942 Generator Ground Fault_ 83 ft

TIA 942 Generator Ground Fault_ 83 ft

(OP)
TIA Standard TIA-942 "Telecommunications Infrastructure Standard for Data Centers has Table 10: Tiering reference guide (electrical). Under Standby Generator System there is a line "Individual 83 ft. Ground Fault Protection for each Generator" Does anybody knows the meaning of 83 ft in case of ground fault protection? Thank you for any clarification of this issue.  

RE: TIA 942 Generator Ground Fault_ 83 ft

(OP)
Please make the appropriate correction in your copy of TIA based on the response from the Chair of TIA 9422:

"I spoke at length with my colleague who worked with me to develop the electrical section of Table 10.  The 83 ft is a typo.   The correct requirement is 'Individual 87G ground fault detection for each Generator' not 'Individual 83 ft. Ground Fault Protection for each Generator'."
