**1. [SCOPE]{.underline}**

The work shall consist of furnishing, installing, and testing a complete
electrical system as specified herein.

**2. [DRAWINGS]{.underline}**

The drawings are not intended to shoo in full detail all features of the
work. The contractor shall take all measurements and do all cutting on
the job site. The locations of conduit, boxes, switches, fixtures,
control panels, and electrical outlets are approximate only and the
exact locations shall be checked to determine that they clear all
openings, structural members, pipes, and other fixed equipment.

**3. [MATERIALS]{.underline}**

The Contractor shall submit a complete list of material, fixtures, and
equipment to be used which shall show the catalog numbers, cuts,
diagrams, and technical ratings. Each type of material shall be of the
same make and quality throughout the entire job.

**4. [RIGID CONDUIT]{.underline}**

Rigid steel conduit shall be hot-dipped galvanized. All conduit embedded
in concrete shall have a minimum of two (2) inches of concrete covered
on all sides when the concrete is exposed to the air and three (3)
inches of concrete cover when adjacent to the earth. Electric Metallic
Tubing (EMT-thin-wall) shall not be used.

**5. [FLEXIBLE CABLE MOTOR CONNECTIONS]{.underline}**

The motors shall be connected with lead covered, galvanized spiral
armored cable. An anti-short bushing shall be used in each spiral,
armored cable termination. All bends shall be so made that the armor
will not be injured and the radius of the curve of the inner edge of any
bend shall be not less than five (5) times the outside diameter. The
motors of the armored cable connections shall have a bonding strip,
extra conductor, or a jumper for grounding continuity.

**6. [FLEXIBLE CONDUIT]{.underline}**

Flexible conduit connections shall be watertight flexible couplings,
Crouse-Hinds Series ECH or equal. For couplings over 2 feet long, they
shall be rigidly supported.

**7. [CONDUIT INSTALLATION]{.underline}**

All conduit shall be installed in accordance with Article 346 of the
National Electrical Code. All exposed conduit shall be parallel to or
perpendicular to the beams. Where changes in direction of run require a
box or fitting, they shall be cast, threaded hubs with gaskets and
malleable or cast cover.

**8. [CONDUIT SUPPORTS]{.underline}**

Conduit shall be supported on approved type of galvanized wall brackets,
ceiling trapezes, and concrete expanding metal inserts, and secured by
means of metal lag screws with lock washers. Threaded studs driven in by
p power charge and provided with lock washers and nuts are acceptable.
Wooden plugs and fibrous, plastic, or lead inserts are not acceptable.
'All clamps and straps shall fit the conduit snugly.

**9. [BUSHINGS AND LOCKNUTS]{.underline}**

Conduit shall be securely fastened to all enclosures. Each outside
locknut shall be firmly tightened against each inside bushing or locknut
for electrical continuity. Where grounding is necessary, grounding
wedges or solderless ground clamps shall be used.

**10. [JUNCTION, OUTLET, AND PULL BOXES]{.underline}**

All boxes and fittings shall be cast and watertight with threaded hubs,
gaskets, and malleable or cast covers. The number of wires in a box
shall be in accordance with NEC, section No. 370-6.

**11. [RECEPTACLE OUTLETS]{.underline}**

The receptacles shall be 15 amp, 125 volt, heavy duty, grounded and of
the standard type capable of receiving two-wire parallel bladed plugs or
three-wire plugs having two parallel blades and one ground prong.

**12. [WIRE]{.underline}**

All wire shall be 600 volt; code grade copper marked in accordance with
NEC. All wire in conduit for receptacles, lighting, and controls shall
be Type RHW. Wire No. 10 AWG and smaller, except control cable shall be
solid. Wire No. 8 AWG and larger shall be stranded. Wires shall not be
pulled into conduit until construction has advance to a point where
wires will not be damaged after they have been installed.

**13. [GROUNDING]{.underline}**

All equipment, including pumps, motors; cabinets, intake and discharge
piping, and structural steel framework shall be grounded in accordance
with NEC.

Grounding wire shall have a minimum earth cover of 18 inches and 2
inches cover when embedded in concrete.

Connectors and lugs shall be copper alloy of the bolted type for above
ground connections. All connections made in the earth or concrete shall
be properly thermo-welded, Caldwelded, SIL FOS method, or brazed. All
connections must be electrically and mechanically sound

Ground rods shall be made of copper, copper clad steel, or hot-dip
galvanized stiff carbon steel not less than 3/4 inch diameter and 8 feet
long, and driven full length into the earth without being bent or
damaged.

**14. [WIRE CONNECTORS AND LUGS]{.underline}**

Pigtail connections of No. 8 AWG wire and smaller shall be made with
Scotchlock or equal, and insulator or copper splice cap and insulator.
All splice caps shall be indented with the proper size pressure tool.
Preinsulated connectors of porcelain or bakelite jacket types
(wire-nuts), with, or without metal inserts shall not be used. All other
connectors and lugs shall be solderless, copper or copper alloy, bolted,
crimp, or indenter types. All connections must be electrically and
mechanically sound.

**15. [CIRCUITS]{.underline}**

The Contractor shall furnish a complete set of correctly sized circuit
breakers with combined delayed overload protection and fast acting
current limiting actin for short circuits. Circuit breakers shall be
sized for motor starting and running protection.

**16. [SERVICE ENTRANCE]{.underline}**

A meter base connected to a ground rock shall be installed as specified
by the electric power supplier. The service drop shall meet all code
requirements and shall be accomplished with suitable equipment for
exterior work.

**17. [WIRING DIAGRAM]{.underline}**

A complete as-built wiring circuit drawing(s) with all points identified
shall be furnished in permanent plastic permanently affixed to the
inside of the control cabinet door. All terminals and wires in the
control cabinet shall be labeled or tagged as shown on the wiring
diagram, a permanent black image on a dimensional, stable base film.

**18. [TESTS]{.underline}**

Upon completion of the electrical and control system installation, the
equipment and controls shall be tested to demonstrate that the
requirements of these specifications have been met. The Contractor shall
furnish all instruments and personnel required of the tests. Tests shall
be performed in the presence of the Contracting Officer or his
authorized representative.

**19. [INSPECTIONS]{.underline}**
