Buffalo Wild Wings

B. Type: Conduit shall be rigid galvanized steel. In lieu of rigid galvanized steel the following
conduits may be used only as specified herein:
2.3 CONDUIT FITTINGS
1. Intermediate Steel Conduit may be used in all locations.
2. Electric Metallic Tubing (EMT): May be used in dry locations for wiring below 600
volts in all interior spaces not in direct contact with earth or where exposed to
weather using steel watertight compression fittings and backstraps. EMT shall
not be installed in concrete slabs or in soil.
3. Flexible Metal Conduit: Flexible metal conduit (FMC) or liquid tight flexible metal
conduit (LFMC) shall be permitted only in the following locations:
a. Flexible metal conduit may be used in masonry wall construction for
‘fishing’ of circuitry. Liquid tight flexible metal conduit (LFMC) shall be
used for final connections to equipment such as motors, fixed equipment,
electric heating equipment, food service equipment, etc. LFMC shall be
used in lengths no longer than thirty-six.. FMC ‘fished’ in masonry
construction shall not be run horizontally and shall transition to EMT as
soon as practical when leaving the wall construction from its vertical run.
b. Fittings shall be steel set screw type for smaller sizes and steel, clamp
type for larger sizes.
c. LFMC shall have fully sized and insulated grounding conductor within the
conduit.
d. Concealed within equipment cabinets if approved by Architect/Engineer.
4. Rigid Non-Metallic Conduit: May be used only where run in soil or in concrete
slabs on grade unless otherwise noted on Drawings or specified herein.
a. Conduit entries into pole bases or concrete pads shall be rigid
galvanized steel. Conduits emerging out of floor slab-on-grade shall be
rigid galvanized steel.
b. All non-metallic conduits shall have a grounding conductor sized in
accordance with Table 250-95 of the NEC, but not less than #12AWG.
Contractor shall increase conduit size to accommodate the grounding
conductor.
5. Metalclad Cable (MC): MC cable may be used for light fixture connections in
accessible ceiling and within casework where permitted by code. All MC cable
shall have fully rated and insulated grounding conductor. MC cable shall not be
used in walls or non accessible ceilings.
A. Rigid Galvanized Steel Conduit and Intermediate Metal Conduit:
1. Couplings, locknuts and bushings shall be threaded type. Threadless couplings
shall not be used without prior approval of Engineer.
2. Locknuts shall be of the conduit type.
3. Bushings shall consist of an insulating insert molded or locked into metallic body
fitting. Bushings made entirely of metal or non-metallic material are not permitted.
4. Where conduit is installed in concrete, Erickson-type and set-screw couplings
may be used to complete a conduit run. Set-screw fittings shall be approved for
concrete installation and shall be case-hardened steel with hex head and cup
point to firmly set in conduit wall for positive ground.
5. Threaded cast iron type sealing fittings shall be used. Fittings used to prevent
passage of water vapor shall be continuous drain type. Fittings in concealed work
shall be installed in a flush steel box with blank coverplate having the same finish
as that of other electrical plates in room.
