GENERAL NOTES:

1. ALL WORK SHALL CONFORM TO THE REQUIREMENTS OF THE SPECIFICATIONS, DRAWINGS

LATEST EDITION OF THE NATIONAL ELECTRIC CODE (NFPA 70), NATIONAL ELECTRIC

VEHICLE INFRASTRUCTURE (NEVI) REQUIREMENTS, NATIONAL ELECTRIC SAFETY CODE

(NESC), AND THE REGULATIONS OF OTHER AUTHORITIES HAVING JURISDICTION.

2. LOCATIONS OF EQUIPMENT AND RACEWAYS UNLESS SPECIFICALLY DIMENSIONED ARE

APPROXIMATE ONLY. CONTRACTOR SHALL ESTABLISH EXACT LOCATION IN THE FIELD TO

CLEAR ALL OBSTACLES.

3. CONDUITS, JUNCTION BOXES AND OTHER ELECTRICAL EQUIPMENT INSTALLED SHALL NOT

INTERFERE WITH THE OPERATION OF WINDOWS, DOORS, CRANES, ETC.

4. ALL METALLIC CONDUITS AND RACEWAYS SHALL BE ELECTRICALLY CONTINUOUS AND

GROUNDED.

5. ALL CONDUIT PENETRATIONS THROUGH FIRE RATED WALL AND FLOORS SHALL BE

SEALED WITH FIRE RESISTANT SEALANT.

6. THE ELECTRICAL CONTRACTOR SHALL MAINTAIN OPERATION OF EXISTING FACILITIES AS

REQUIRED. PROVIDE NECESSARY TEMPORARY CONNECTIONS BETWEEN NEW AND

EXISTING WORK, AT NO ADDITIONAL COST.

7. THE ELECTRICAL CONTRACTOR SHALL PROVIDE ALL WIRING DEVICES REQUIRED BY N.E.C.

INCLUDING BUT NOT LIMITED TO DISCONNECT SWITCHES, ETC.

8. PULL BOXES SHALL BE SIZED, FURNISHED AND INSTALLED AS REQUIRED BY THE N.E.C.

PROVIDE PULL BOXES OR PULL TYPE CONDUITS AS REQUIRED TO CONFORM TO N.E.C.

DETERMINE WHETHER TO USE A SINGLE PULL BOX, GROUP OF PULL BOXES OR PULL

CONDULETS BASED ON ACTUAL FIELD CONDITIONS AND AS APPROVED BY THE ENGINEER.

9. THE CONTRACT DRAWINGS ARE DIAGRAMMATIC IN NATURE AND NOT EVERY PULL BOX,

DETAIL OR EXACT LOCATION OF EQUIPMENT OR CONDUIT IS SHOW. EXISTING CONDITIONS

SHALL BE VERIFIED IN THE FIELD PRIOR TO COMMENCING ANY FABRICATION, ORDERING

ANY MATERIAL, OR PERFORMING ANY WORK. ANY DEPARTURE FROM CONCEPT SHOWN

ON THE CONTRACT DRAWINGS SHALL BE SUBMITTED TO THE ENGINEER FOR APPROVAL.

10. UPDATE ALL PANEL DIRECTORIES WHERE EXISTING CIRCUITS ARE MODIFIED.

11. ALL WIRING AND EQUIPMENT SHALL BE UL LISTED & LABELED, NEW AND INSTALLED IN

CONFORMANCE WITH THE LATEST RHODE ISLAND STATE BUILDING AND ELECTRICAL

CODES AND NFPA 72.

12. THESE ARE STANDARD COVER SHEET ABBREVIATION LISTS AND SYMBOLS. DISREGARD

UNUSED ABBREVIATIONS AND SYMBOLS.

13. PATCHING AND MAINTAINING FIRE RATINGS ARE THE RESPONSIBILITY OF THE ELECTRICAL

CONTRACTOR.

14. ELECTRICAL CONTRACTOR SHALL COORDINATE ROUTING OF CONDUITS AND THE

INSTALLATION OF JUNCTION BOXES IN THE FIELD.

15. UNLESS OTHERWISE INDICATED, ALL WIRING SHALL BE IN ACCORDANCE WITH

MANUFACTURER RECOMMENDATIONS. CONDUIT SHALL BE 3/4" MINIMUM.

16. THE DRAWINGS ARE SCHEMATIC AND ARE NOT INTENDED TO SHOW ALL EXISTING

INTERIOR WALLS OR EVERY PROPOSED OFFSET OF FITTING. THE DRAWINGS ARE NOT

INTENDED TO SERVE AS SHOP DRAWINGS.

17. ELECTRICAL CONTRACTOR TO FURNISH A COPY OF THE ELECTRICAL PERMIT

APPLICATION AND COMPLETED PERMIT TO THE OWNER.

18. ELECTRICAL CONTRACTOR SHALL IMMEDIATELY CHECK ALL DRAWINGS FURNISHED UPON

THEIR RECEIPT AND SHALL PROMPTLY NOTIFY THE AUTHORITY OF ANY DISCREPANCIES.

19. ELECTRICAL CONTRACTOR SHALL FIELD VERIFY ALL MEASUREMENT BEFORE LAYING OUT

THE WORK AND SHALL BE RESPONSIBLE FOR ANY ERRORS WHICH MIGHT HAVE BEEN

AVOIDED THEREBY.

20. PROVIDE 10 AWG PHASE, NEUTRAL, AND GROUND CONDUCTORS FOR 120 VOLT, 20

AMPERE BRANCH CIRCUITS EXCEEDING 100 FEET AND FOR 277 VOLT, 20 AMPERE

CIRCUITS EXCEEDING 200 FEET.

21. VERIFY EXACT MOUNTING CONDITIONS AND PROVIDE APPROPRIATE ACCESSORIES AND

HARDWARE TO ACCOMMODATE REQUIREMENTS.

22. PROVIDE A GROUND CONDUCTOR IN EACH ELECTRICAL RACEWAY IN ACCORDANCE WITH

THE LATEST NATIONAL ELECTRICAL CODE AS FOLLOWS:

A. EQUIPMENT GROUND WIRES (INSULATED GREEN CONDUCTORS) SHALL BE PROVIDED IN

ALL FEEDERS AND ALL BRANCH CIRCUITS.

B. ALL FLEXIBLE METAL OR LIQUID-TIGHT CONDUIT CONNECTIONS TO EQUIPMENT MOTORS,

LIGHTING FIXTURES, ETC. SHALL CONTAIN EQUIPMENT GROUND WIRES. FLEXIBLE METAL

CONDUIT SHALL NOT BE USED AN AN EQUIPMENT GROUND CONDUCTOR.

C. ALL DEVICES, EQUIPMENT, FIXTURES, ETC. SHALL BE GROUNDED BY THE USE OF A

PROPERLY SIZED EQUIPMENT GROUNDING CONDUCTOR. MECHANICAL/ELECTRICAL

BONDS OF THE METALLIC RACEWAY SYSTEM SHALL ALSO BE MAINTAINED.

23. CONTROL AND POWER CABLES SHALL RUN IN SEPARATE CONDUITS.
