FOR INFORMATION PURPOSE. HOWEVER, THE ITEMS SHOWN ARE NOT NECESSARILY COMPLETE,

ELECTRICAL CONTRACTOR (E.C.) TO FIELD VERIFY ALL DEMOLITION ITEMS AND PROVIDE REMOVAL OF ALL DEVICES ACCORDINGLY. SEE RELATED NOTES ON MAINTAINING SEVICE TO NON-DEMOLITION AREAS. E.C. SHALL REMOVE ALL EXISTING LIGHTING FIXTURES, ASSOCIATED SWITCHES/DIMMERS, EXIT LIGHTS, RECEPTACLES, TELEPHONE, DATA, MISC. OUTLETS WHERE SHOWN IN DEMOLITION AREAS. REMOVE CONDUIT/WIRE BACK TO PANEL(S) UNLESS RE-USED FOR NEW AND/OR RELOCATED WORKS. EXISTING CONDUIT/WIRE WITH ADEQUATE CAPACITY FOR NEW AND/OR EXISTING LOADS MAY BE RE-USED. SIMILARLY FOR COMMUNICATION SYSTEM CONDUIT/WIRE (REMOVE BACK TO CONTROL PANEL(S) IF NOT RE-USED). LIGHT FIXTURES IN GOOD CONDITION MAY BE RE-USED IF SO INDICATED ON DRAWINGS. LIGHT FIXTURES TO BE RE-USED SHALL BE RE-LAMPED AND CLEANED. REPLACE BALLASTS IF NOISY OR INOPERATIVE. E.C. TO EXAMINE CONDITION OF ALL EXISTING BALLASTS, IF ANY BALLASTS ARE SUSPECTED TO CONTAIN PCB'S, DO NOT DISPOSE OF; SET SUCH ASIDE AND NOTIFY

OWNER FOR AUTHORIZED REMOVAL. REMOVE SUCH BALLASTS IN STRICT COMPLIANCE WITH

FEDERAL, STATE AND LOCAL LAWS AND ORDINANCES. BALLASTS DATED PRIOR TO 1976 OR NOT SPECIFICALLY MARKED "NO PCB'S" SHALL BE CONSIDERED TO CONTAIN PCB'S. FIXTURES NOT INDICATED FOR RE-USE SHALL BE DELIVERED TO A LOCATION TO BE SPECIFIED BY OWNER. ALL

90-DEGREE C CONDUCTOR MAY BE USED BUT ONLY AT 60-DEGREE C AMPACITY. EXCEPTIONS:

HIGHER TEMPERATURE CABLE ARE ALLOWED PROVIDED THE EQUIPMENT IS LISTED AND IDENTIFIED FOR USE WITH THE HIGHER RATED CONDUCTORS. (B) CIRCUITS RATED MORE THAN 100 AMP OR

CONDUCTOR LARGER THAN #1 AWG: USE 75-DEGREE C RATED CONDUCTORS ONLY. 90-DEGREE C

CONDUCTOR MAY BE USED BUT ONLY AT 75-DEGREE C AMPACITY. EXCEPTIONS: HIGHER

TEMPERATURE CABLE ARE ALLOWED PROVIDED THE EQUIPMENT IS LISTED AND IDENTIFIED FOR USE

WITH THE HIGHER RATED CONDUCTORS.

MANUFACTURERS SUCH AS GE MAY HAVE LARGER DIMENSIONS. IT IS THE RESPONSIBILITY OF THE ELECTRICAL CONTRACTOR TO PROVIDE EQUIPMENT WITH SIMILAR DIMENSIONS THAT WOULD FIT IN

THE SPACE NOTED.

• VERIFY LOCATION OF ALL OUTLETS (POWER & COMMUNICATION) WITH OWNER/ARCH PRIOR TO ROUGH-IN. OWNER RESERVES THE RIGHT TO MOVE ANY OUTLETS 5 FEET IN ANY DIRECTION PRIOR TO ROUGH-IN. ALL RECEPTACLES WITHIN 6 FEET OF ANY WET AREA (EXAMPLE : SINK, DISHWASHER, ETC..) SHALL HAVE GROUND FAULT PROTECTION, WHETHER SPECIFICALLY INDICATED OR NOT ON

DRAWINGS.

• MOUNTING HEIGHTS OF ALL OUTLETS (RECEPTACLES, SWITCHES, TELEPHONE, DATA, ETC.) IN AREAS WITH COUNTERTOP SHALL BE VERIFIED WITH ARCH/OWNER. GENERALLY ALL OUTLETS ARE TO BE

MOUNTED ABOVE COUNTERTOP EXCEPT OUTLETS FOR DISPOSERS, UNDERCOUNTER DISHWASHER,

UNDERCOUNTER REFRIGERATORS ETC. REFER TO ARCH INTERIOR ELEVATIONS.

LOADS ARE INDICATED AS (EST.) ON PLANS, RISER DIAGRAMS AND/OR PANEL SCHEDULES.

CONTRACTOR SHALL BID THE PROJECT USING THE ESTIMATED FEEDER/BREAKER/SWITCHES SHOWN

ON DRAWINGS. HOWEVER, THE CONTRACTOR IS RESPONSIBLE FOR CONFIRMATION AND

VERIFICATION OF ALL SUCH ESTIMATED LOADS WITH THE APPROPRIATE VENDORS/SUPPLIERS. ALL

SHOP DRAWINGS SUBMITTED BY THE CONTRACTOR SHALL INCLUDE CERTIFICATION THAT THE

CONTRACTOR HAS CONFIRMED/VERIFIED ANY ESTIMATED LOADS SHOWN ON THE DRAWINGS.

CONTRACTOR WILL NOT BE DUE ANY ADDITIONAL COMPENSATION FOR HIS FAILURE TO VERIFY THE ESTIMATED LOADS SHOWN ON DRAWINGS. PROVIDE CREDIT TO THE OWNER IF ACTUAL LOADS ARE SMALLER THAN ESTIMATED LOADS, CREDIT SHALL BE GIVEN FOR SIZE REDUCTION ON FEEDER/

BREAKER/ SWITCHES.

BE OMITTED IF NOT REQUIRED BY EQUIPMENT.

• THE ELECTRICAL CONTRACTOR SHALL FAMILIARIZE THEMSELVES WITH THE DRAWINGS OF ALL

OTHER TRADES ON THE PROJECT. ELECTRICAL OR SYSTEMS CONNECTIONS INDICATED ON

ARCHITECTURAL, MECHANICAL, CIVIL, STRUCTURAL AND ALL OTHER DRAWINGS WHICH ARE PART OF THIS PROJECT SHALL BE CONSIDERED A PART OF THIS CONTRACT AND SHALL BE PROVIDED BY THE

ELECTRICAL CONTRACTOR AT NO EXTRA COST TO THE OWNER.

• THE ELECTRICAL DRAWINGS ARE DIAGRAMMATIC IN NATURE AND AS SUCH SHALL NOT BE SCALED.

TO ROUGH-IN OF SERVICE EQUIPMENT AND WIRING. COORDINATE MOUNTING HEIGHTS OF ALL

DEVICES WITH ARCHITECTURAL PLANS, SECTIONS, ELEVATIONS AND CASEWORK DRAWINGS.

• THE CONTRACTOR SHALL BE RESPONSIBLE FOR DETERMINING THE EXACT ROUTING OF WIRING AND CONDUITS AND SHALL BE RESPONSIBLE FOR SIZING ALL BRANCH CIRCUIT WIRING TO LIMIT VOLTAGE

DROP TO 3%. CONTRACTOR SHALL SIZE CONDUIT TO ACCOMMODATE WIRING PER NEC.

• WIRING AND CONDUIT SIZES INDICATED IN PANEL SCHEDULES ARE MINIMUM ONLY. CONTRACTOR SHALL BE RESPONSIBLE FOR DETERMINING EXACT WIRING AND CONDUIT SIZES. CONTRACTOR SHALL PROVIDE SPLICE BLOCKS AND REDUCING PINS AS REQUIRED TO TERMINATE WIRING AND MAKE FINAL

CONNECTIONS.

• ELECTRICAL BOXES IN FIRE RATED PARTITIONS SHALL NOT EXCEED 16 SQUARE INCHES IN AREA (IF 4" x 4"), SHALL BE MADE OF STEEL AND SHALL BE SUCH THAT THE CUMULATIVE AREA OF BOX "CUTOUTS" IN THE FIREWALL DOES NOT EXCEED 100 SQUARE INCHES PER 100 SQUARE FEET OF WALL AREA. ELECTRICAL BOXES ON OPPOSITE SIDES OF THE SAME FIREWALL SHALL BE SEPARATED

BY A HORIZONTAL AND VERTICAL DISTANCE OF NOT LESS THAT 24 INCHES. THE ELECTRICAL

CONTRACTOR SHALL MAKE MINOR ADJUSTMENTS, AS NECESSARY, TO ELECTRICAL BOX LOCATIONS

TO ENSURE COMPLIANCE WITH THIS REQUIREMENT SINCE BOX LOCATIONS ARE TYPICALLY NOT

DIMENSIONED ON THE DRAWINGS. CONSULT ARCHITECT IF CLARIFICATION IS REQUIRED.

• ALL CONDUIT SHALL BE CONCEALED IN WALLS, FLOORS, ABOVE CEILING OR THROUGH MILLWORK UNLESS OTHERWISE NOTED. AT TIMES CONDUIT ROUTING IS SHOWN FOR CLARITY AND IN NO WAY PROVIDES THE CONTRACTOR ABILITY TO NOT PROVIDE CONCEALED CONDUIT AT ANY POINT. REFER

TO SPECIFICATIONS FOR CONDUIT AND WIRING REQUIREMENTS BASED ON APPLICATION.

• IN ALL PARTITIONS AND WALLS REQUIRING ACOUSTIC INSULATION OR AN STC RATING, OUTLETS, SWITCHES, ETC. SHALL NOT BE LOCATED BACK TO BACK; THEY SHALL BE OFFSET AT LEAST 16", SHALL NOT OCCUPY THE SAME STUD CAVITY AND SHALL BE SEALED.
