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