(LFMC) not exceeding 6 feet in length shall be used only for connections to motors or
equipment subject to movement or vibration. Exceptions may be granted for renovation
projects allowing over 6’ of flexible conduit where 1) in location that are not accessible
2) for the connection of light fixtures provided they have an insulated ground wire sized
in accordance with NEC 3) Other special circumstance with prior approval from OUBO
electrical engineer. Flexible conduit may also be used for connections to systems
furniture and under floor power requirements for computer server room applications.
All wiring shall be run in EMT conduit, surface metal raceway or cable tray. EMT conduit
from the communications or power or control wiring (under 50V) wall outlet box may
terminate several inches above the ceiling where lay-in ceiling tile is used. Cabling above
the ceiling shall be neatly bundled and attached to or independently supported from the
building structure above. Wiring, conduit or cable shall not be laid on the ceiling system
or attached to the ceiling suspension wire. Support from the building structure.
All empty conduits shall have a 65-lb test polymer (or equivalent) pull string tied off at
both ends. All conduits shall be concealed in finished areas. Surface mounted raceways
may be used for horizontal distribution of electrical and data cabling in computer rooms,
computer classrooms and research laboratories. Pre-existing conditions of surface
mounted wiring and conduit does not constitute permission to add surface mounted
hardware and raceway.
Conductors:
BSRV 6.2.6 DEVICES
All conductors shall be copper with 75 °C insulation or better. All power and lighting
circuit conductors shall be #12 AWG or larger. #8 AWG and larger shall be stranded
conductors and #10 AWG and smaller shall be solid conductors. Minimum control wires
shall be #14 AWG and minimum signal wire no smaller than #18 AWG unless otherwise
recommended by manufacturer.
All new circuits shall have a green equipment-grounding conductor sized per NEC Article
250. All new electrical equipment such as switchboards, transformers and generators
shall have grounding conductor sized per NEC Article 250.
No more than three single phase circuits or eight (8) current-carrying conductors shall
be run in a single conduit.
Ground fault circuit interrupter outlets or breakers are required on all power outlets
within 6-feet of water sources. Where the presence of water or grounded surfaces
contribute to a hazardous environment, ground fault protection is required.
All devices shall be 20A, heavy-duty specification (minimum) grade devices. Residential
grade devices are not permitted.
Receptacles shall be mounted with the ground pole in the UP position unless otherwise
directed.
