2. Introduction
This Electrical Design Basis describes the in battery limits Electrical Systems (bonding, control,,grounding, lighting and power) that will be designed by the members of the Electrical Design Section for the Aroclor Expansion Project.
The appropriation for the electrical facilities is as follows:
Code Category
01 04 (Electrical only) 10 13
Total capital for Equipment, material and labor
80 90, 92, & 93 (Expense)
Amount
$15,500 5,000 0
26,000 $46,500
$10,000 $14,000 Approximately
A two thousand dollar overrun is expected in the code 13 account due to additional lighting.
3. General Description of the Electrical Facilities
Installation in the tank farm area includes 9 pump motors with local and remote pushbuttons, and 3 agitator motors with local pushbuttons. Approximately 8 street type lighting fixtures for loading docks and Area lighting, and approximately 15 lighting fixtures in the tank farm area. All mercury vapor lights will be constant wattage type.
In the drumming and flaking area installations consist of 20 motors, a motor control center for motors in both areas,
and approximately 23-175 watt mercury vapor lights for the building.

A 300 KVA Pole mounted Transformer will be installed to feed the motor Control Center. The existing HB 40 (200 KVA) Transformer will be removed and scrapped. The existing HB 40 Load will be fed by a new feeder from the existing Aroclor Motor Control Center.
Because of building locations and grading work an extensive amount of pole line replacement and rerouting will be done for CEA 1430 and CEA 1452.
4. Project Risk
There is no risk on this project.
5. Electrical Equipment and Material Removals.
The existing HB-40 Transformer is to be removed and scrapped. This.Transformer (200 KVA) is 30 to 40 years old and if reused would become a safety and housekeeping problem.
The existing feeder from the HB-40 Transformer to the HB40 load will be removed.

Approximately 18 new drawings and revisions to 3 existing drawings will be needed for this project. See attached list.
8. Electrical Purchasing
CED will purchase all motors, motor control centers, pushbutton, stations, panels, lighting fixtures, power transformers, circuit breakers, feeder cables, multi-conductor cables and cable tray. The contractor will provide all wire (except cables) conduit, conduit fittings, supports, lamps, fuses (other than in new motor control center), and wire markers.

9. Construction and Startup Assistance Provided or Arranged for by the Electrical Design Section
The Electrical Equipment and controls on this project are not complicated. sNo vendor assistance is anticipated and assistance by the Electrical Design Group should be minimal but further coverage can be made available at the request of the project Manager.
10. Completion Criteria
This project will be considered to be Electrically complete when all electrical equipment that was scheduled for removal has been removed, and all new electrical equipment has been properly installed and the operation of the new Electrical Equipment has been demonstrated to be satisfactory to .the project Manager and to the Plant Manager or his designee.
11. Electrical Codes
All Electrical installations shall be in accordance.with the 1965 National Electrical Code.
12. Electrical Standards
This project will use those electrical items and materials that are covered by the CED Electrical Standards as applicable to the Anniston Plant.
13. Hazard Classification
Liquid biphenyl will be the only hazardous material connected with this project. Liquid biphenyl has a flash point of 113C and biphenyl dust under certain conditions can explode. However, by proper temperature control (below 80C) of the liquid and separation of main electrical equipment from the biphenyl flaker area the project will be basically non-hazardous. Some TEFC or encapsulated motors and explosion proof controls may be used near the biphenyl area after firther evaluation.
14. Special Corrosive or Dust Conditions
NONE
15. Special Protective Coatings and Equipment Painting
All painted equipment is to have a paint system which is 5 mils thick.
16. Power Supply Requirements and Source of Power

A 480 volt 400 Amp (500 MCM) feeder from the new 300 KVA transformer to the new MCC will be installed on this project.
17. Wiring Systems
All wire will be copper and stranded. No conductor smaller than #14 will be installed. Control wire will be #14, Lighting conductors will be #12 and above. Type THW 600 volt insulation is specified.
18. Supports for Conduit and Equipment Mounting
A cable tray will be routed atop the pipe bridge from the motor control center.to the tank farm area. In the flaking and drumming area trapeze type hangers and beam clamps connected to the building steel will be used to support the conduit.
19. Motors
There will be approximately 35 motors installed, all motors
are 3 phase induction type with TEFC or encapulated enclosures.
See attached list.
20. Motor Control Centers
The motor control center shall be a front access NEMA 1A enclosure with Class I Type B wiring and fusible disconnect switch combination starters.
The motor control center shall consist of approximately 18-size 1 starters, 12-size 2 starters, 1-3 pole main disconnect 400 ampere switch, 5-60 ampere 3 pole disconnects. All starters shall have 480 volt to 120 volt control transformers. A watt hour meter will also be mounted in the MCC.
21. Individually Mounted Motor Starters

All starters other than sewage pump starters will be equipped with 480/120 volt control transformer with one side of the secondary fused, the other side grounded. Pumps in the tank farm will have local and remote pushbuttons, other motors will have local pushbuttons only. No complicated interlocking involved. Sewage pumps will have a combination float switch alternator control with a manoff-auto selector switch, and 270 to 120v. control transformers.
23. Conductor Identification
Control Circuit Conductors will be labeled at all terminal blocks and devices using Brady 500 wire markers with numbers and/or letters that are indicated on the appropriate Electrical drawings.
24. Power Receptacles
NONE
25. Lighting Systems
Approximately 15-175 watt light fixtures will be installed in the tank farm area, approximately 6-400 watt street type light fixtures will be installed for the loading dock and tank farm perimeter, and approximately 23-175 watt light fixtures will be used in the drumming and flaking area. All mercury vapor fixtures will be constant wattage type. Some incandescent lighting will be installed in the manufacturing area to provide light after a power failure. No provisions for emergency lighting system. Lighting transformer and panel will be located in the new warehouse.
26. Bonding and Grounding (Earthing) Systems
Power Systems All noncurrent carrying parts of electrical Equipment will be connected to the motor control center ground buss through the conduit system and with grounding type conduit bushings at the equipment. An extra wire connected to the ground buss in the motor control center will be run in the cable tray to insure a proper ground in the tank farm area.
