SHALL BE TAKEN INTO ACCOUNT THROUGHOUT THE PROJECT.

4. USE EXISTING ROUTING FOR NEW FEEDERS AND BRANCH CIRCUITS WHENEVER POSSIBLE. IF

A PATH IS FOUND TO BE UNTENABLE, CONFIRM NEW ROUTING WITH THE COR. WIRING SHALL

BE INSTALLED WITHIN CONDUIT WHERE EXISTING PATHS INCLUDE CONDUIT.

5. USE EXISTING HOLES AND OPENINGS TO INSTALL CONDUIT AND CABLE. WHERE NO USABLE

PATH EXISTS, CUT NEW HOLES. COORDINATE SIZE AND LOCATIONS OF DRILLED HOLES AND

CUT OPENINGS WITH THE COR.

6. IT IS RECOMMENDED THAT THE CONTRACTOR VISIT AND BECOME FAMILIAR WITH THE SITE

PRIOR TO SUBMITTING BID.

7. THE TERM "REMOVE" MEANS DISCONNECT AND REMOVE THE DEVICE INCLUDING OUTLETS,

BRANCH CIRCUIT WIRING AND RACEWAY.

12. PROVIDE ENGRAVED, PHENOLIC NAMEPLATE PANELS, SAFETY SWITCHES, CABINETS, ETC,

TO IDENTIFY THE UNIT AND THE SOURCE PANEL AND CIRCUIT NUMBER.

13. ALL ELECTRICAL MATERIALS SHALL BE TEMPERATURE RATED FOR 90°C.

DESIGN ASSIST NOTES

1. ELECTRICAL WORK RELATED TO MECHANICAL SYSTEMS SHALL BE PROVIDED USING A

DESIGN-ASSIST APPROACH. ELECTRICAL CONTRACTOR SHALL PREPARE FINAL ELECTRICAL

DESIGN DOCUMENTS BASED ON MECHANICAL EQUIPMENT REQUIREMENTS, FIELD

CONDITIONS, AND APPLICABLE CODES. FINAL DESIGN SHALL BE SUBMITTED FOR ENGINEER

AND OWNER REVIEW PRIOR TO INSTALLATION. DRAWINGS INDICATE GENERAL INTENT ONLY

AND DO NOT REPRESENT A COMPLETE ELECTRICAL DESIGN.

2. CONTRACTOR SHALL VERIFY EXISTING ELECTRICAL CAPACITY AND INFRASTRUCTURE AND

NOTIFY THE ENGINEER OF ANY DISCREPANCIES PRIOR TO PROCEEDING WITH FINAL DESIGN.

3. ELECTRICAL CONTRACTOR SHALL COORDINATE POWER AND CONTROL WIRING

REQUIREMENTS WITH THE MECHANICAL CONTROLS CONTRACTOR AND EQUIPMENT

MANUFACTURERS.

4. CONTRACTOR SHALL VERIFY ALL MECHANICAL EQUIPMENT ELECTRICAL CHARACTERISTICS,

INCLUDING VOLTAGE, PHASE, MCA, MOCP, AND CONTROL REQUIREMENTS PRIOR TO FINAL

DESIGN.
