Electrical. TR electrical requirements are dependent upon the
number of seats supported in addition to the basic requirements listed in ANSI /
TIA / EIA 569-A. Tables D-2 and D-3 in Appendix D represent the NMCI
electrical requirements for each TR. The ampacity at the service connection
point identified by the government for the TPP will be based upon the demand
load of the equipment. Figure D-2, Appendix D, represents a typical one line for
the MC / IC equipment in the TR.

Fire Protection. Fire Protection guidelines for unoccupied
telecommunications spaces will be in accordance with UFC 3-600-01, Design:
Fire Protection and Engineering for Facilities. Based on NMCI contract
administration, these spaces are network distribution areas, are not considered
"critical facilities", and are not required to comply with NFPA 75, Standard for
Protection of Information Technology Equipment or NFPA 76, Recommended
Practice for Fire Protection of Telecommunications Facilities. TRs are therefore
not normally required to be fire-rated structures. However, these spaces must be
designed and constructed for 1-hour fire rating.
