above floor. Mount lighting switches. Mount receptacles 18 inches above
finished floor, unless otherwise indicated.
3.1.6
Conductor Identification
Provide conductor identification within each enclosure where tap, splice, or
termination is made. For conductors No. 6 AWG and smaller diameter, color
coding shall be by factory-applied, color-impregnated insulation. For
conductors No. 4 AWG and larger diameter, color coding shall be by plasticcoated, self-sticking markers; colored nylon cable ties and plates; or heat
shrink-type sleeves. Identify control circuit terminations in accordance
with 25 10 00.00 20, SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA)
SYSTEM.
3.1.7
Splices
Make splices in accessible locations. Make splices in conductors No. 10 AWG
and smaller diameter with insulated, pressure-type connector. Make splices
in conductors No. 8 AWG and larger diameter with solderless connector, and
cover with insulation material equivalent to conductor insulation.
3.1.8
Covers and Device Plates
Install with edges in continuous contact with finished wall surfaces without
use of mats or similar devices. Plaster fillings are not permitted.
Install plates with alignment tolerance of 1/16 inch. Use of sectional-type
device plates are not permitted. Provide gasket for plates installed in wet
locations.
3.1.9
Electrical Penetrations
Seal openings around electrical penetrations through fire resistance-rated
walls, partitions, floors, or ceilings in accordance with Section 25 10
00.00 20, SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA) SYSTEM .
3.1.10
Grounding and Bonding
Provide In accordance with NFPA 70. Ground exposed, non-current-carrying
metallic parts of electrical equipment, metallic raceway systems, grounding
conductor in metallic and nonmetallic raceways, telecommunications system
grounds, and neutral conductor of wiring systems. Make ground connection at
main service equipment, and extend grounding conductor to point of entrance
of metallic water service. Make connection to water pipe by suitable ground
clamp or lug connection to plugged tee. If flanged pipes are encountered,
make connection with lug bolted to street side of flanged connection.
Supplement metallic water service grounding system with additional made
electrode in compliance with NFPA 70. Make ground connection to driven
ground rods on exterior of building. In addition to the requirements
specified herein, provide telecommunications grounding in accordance with
TIA J-STD-607-A. Where ground fault protection is employed, ensure that
connection of ground and neutral does not interfere with correct operation
of fault protection.
3.1.10.1
Ground Rods
Provide cone pointed ground rods. The resistance to ground shall be
measured using the fall-of-potential method described in IEEE Std 81.
