1. PROVIDE ELECTRICAL INSTALLATION IN ACCORDANCE WITH ALL STATE CODES.

2. THE CURRENT ADOPTED EDITION OF THE ELECTRICAL CODE IS THE STANDARD FOR THE

ELECTRICAL INSTALLATION. VERIFY WITH LOCAL OFFICIALS WHEN PERMITS ARE OBTAINED.

NOTIFY DESIGN TEAM OF ANY DISCREPANCIES BETWEEN THE PROJECT MANUAL OR

DRAWINGS AND THE GOVERNING CODE.

3. INSTALLATION SHALL FOLLOW REQUIREMENTS OF THE ADAAG –AMERICANS WITH

DISABILITIES ACT.

CODE NOTES - ELECTRICAL

1. INSTALL NEW STANDBY GENERATOR FOR THE ENTIRE BUILDING.

2. GENERATOR TO COMPLY WITH NFPA 110 AND NEC SECTION 702. THIS GENERATOR IS NOT

PROVIDED FOR LIFE SAFETY AND WILL ONLY BE UTILIZED FOR BACKUP POWER.

3. EXISTING LIFE SAFETY SYSTEM (EMERGENCY LIGHTING AND FIRE ALARM) TO REMAIN INTACT AND

OPERATIONAL DURING CONSTRUCTION.

4. EXISTING ELECTRICAL SERVICE IS BEING DOWNSIZED FROM 2000A TO 1100A.

5. RELOCATE CONDENSING UNIT TO MAKE WAY FOR NEW GENERATOR.

6. THE OWNER WILL REPROGRAM SIEMENS DDC SYSTEM TO LAPSE START OF 60 TON CONDENSING

UNIT WHEN ON GENERATOR POWER.

7. ALTERNATE #1: SALVAGE EXISTING SERVICE CONDUCTORS NO LONGER IN USE. REFER TO MORE

NOTES ON SHEET E401.

8. AT PROJECT COMPLETION, ELECTRICAL CONTRACTOR WILL BE RESPONSIBLE TO PROVIDE ARC FLASH CALCULATIONS, LABELING, AND DOCUMENTATION FOR THE "MDP" AND "EXISTING" MDP.

SCOPE

1. INCREASE CONDUCTOR SIZES ON 20A 120V-1 PHASE CIRCUITS EXCEEDING 100 FEET TO

CENTER OF LOAD TO ACCOUNT FOR VOLTAGE DROP.

2. RACEWAYS AND BOXES ARE SHOWN DIAGRAMMATICALLY ONLY AND INDICATE GENERAL

AND APPROXIMATE LOCATIONS. LAYOUTS DO NOT ALWAYS SHOW THE TOTAL NUMBER

OF RACEWAYS OR BOXES FOR THE CIRCUITS REQUIRED, NOR ARE THE LOCATIONS OF

INDICATED RUNS INTENDED TO SHOW THE ACTUAL ROUTING OF THE RACEWAYS.

3. LIGHT FIXTURES, SWITCHES, DEVICES, ETC. ARE SHOWN IN PREFERRED LOCATION.

MODIFY CONDUIT, HANGERS, CIRCUITING, ETC. TO PROVIDE A COMPLETE AND

OPERATIONAL SYSTEM.

4. PROVIDE A DEDICATED GREEN INSULATED GROUND CONDUCTOR TO ALL DEVICES. DO

NOT USE CONDUIT SYSTEM AS THE ONLY EQUIPMENT GROUNDING METHOD.

5. DO NOT INSTALL BOXES BACK-TO-BACK ON OPPOSITE SIDES OF THE SAME WALL.

MAINTAIN MINIMUM OF 8” DISTANCE BETWEEN BOXES WHEREVER APPLICABLE.

6. BALANCE PANEL LOADS DURING INSTALLATION. CIRCUIT NUMBERING SHOWN ON PLANS

MAY BE ADJUSTED TO ACCOMMODATE.

7. PROVIDE TYPED PANEL DIRECTORY AT PROJECT COMPLETION FOR NEW PANELS AND

EXISTING PANELS WITH CIRCUITS MODIFIED DURING PROJECT. USE OWNER’S CURRENT

ROOM NUMBERS AND EQUIPMENT NAMES. PROVIDE UNIQUE CIRCUIT IDENTIFICATION

PER NEC 408.4(A)

8. CONTRACTOR IS RESPONSIBLE FOR OPENINGS IN WALLS, FLOORS, CEILINGS, AND

ROOFS THAT ARE REQUIRED TO COMPLETE THEIR SCOPE OF WORK. SEAL

PENETRATIONS IN ACCORDANCE WITH THE RATING OF THE AFFECTED ASSEMBLY.

REFER TO ARCHITECTURAL CODE PLAN FOR RATED WALLS, FLOORS, AND CEILINGS.

GENERAL NOTE:

UNDERGROUND FACILITIES, STRUCTURES, AND UTILITIES HAVE BEEN SHOWN BASED UPON

INFORMATION OBTAINED FROM FIELD LOCATIONS BY UTILITY COMPANIES, AVAILABLE SURVEYS

AND RECORDS. THEIR LOCATIONS MUST BE CONSIDERED APPROXIMATE ONLY. IT IS ALSO

POSSIBLE THAT THERE MAY BE OTHER UNDERGROUND FACILITIES, STRUCTURES, AND UTILITIES IN

EXISTENCE THAT ARE NOT SHOWN. IT IS THE RESPONSIBILITY OF EACH INDIVIDUAL PARTY

REFERENCING THIS PLAN TO DETERMINE THE EXACT LOCATION AND TYPE OF UNDERGROUND

FACILITIES ON THE SITE. HAND EXCAVATE AT CRITICAL POINTS AS NECESSARY TO VERIFY

LOCATIONS, SIZES, ELEVATIONS, FLOW LINES, ETC. IF A PROBLEM OR INTERFERENCE EXISTS, NOTIFY ARCHITECT/ENGINEER BEFORE PROCEEDING.
