◯ NOTES BY SYMBOL ' ':

1 OVERCURRENT PROTECTION RATING IS UNKNOWN. RECORD THE

OVERCURRENT PROTECTION RATING OF EACH BRANCH CIRCUIT DURING

SWITCHBOARD REMOVAL PHASE TO FACILITATE MATCHING RATINGS TO NEW

CIRCUIT BREAKERS IN NEW EQUIPMENT.

2 ELECTRICAL CIRCUIT BRANCH FEEDING EQUIPMENT AT NETWORK

OPERATIONS CENTER (NOC). ENSURE THIS BRANCH, FROM PANEL 'HE'

THROUGH 'LCR', REMAINS ENERGIZED THROUGHOUT ENTIRE CONSTRUCTION

PERIOD.

3 DISCONNECT EXISTING FEEDER FROM EXISTING GENERATOR AND PREPARE

TO CONNECT TO NEW GENERATOR DOCKING STATION.

4 REFER TO POWER MONITORING SYSTEM NOTES IN THIS SHEET FOR

INFORMATION ON DIGITAL POWER METER REQUIREMENTS. REFER TO

SPECIFICATION SECTIONS 26 24 13 AND 26 09 00 FOR ADDITIONAL

INFORMATION.

5 PROVIDE CIRCUIT BREAKER THAT MATCHES RECORDED OVERCURRENT

PROTECTION RATING OF EXISTING BRANCH CIRCUIT.

6 PROVIDE MAIN CIRCUIT BREAKER WITH LONG-TIME PICK-UP SETTING

REACHING ABSOLUTELY NO HIGHER THAN 3800 A. PROVIDE RED PLACARD

STATING “MAXIMUM LONG-TIME PICK-UP SETTING: 3,800 AMPS” IN WHITE FONT

AND ATTACH IT ON SAME ENCLOSURE SECTION AS MAIN CIRCUIT BREAKER.

7 PROVIDE EXTERIOR SURFACE-MOUNTED TYPE 2 SURGE PROTECTION DEVICE

(SPD), RATED AT 300KA/PHASE MINIMUM. CONNECT SPD TO LOAD BUS VIA

DEDICATED CIRCUIT BREAKER MOUNTED IMMEDIATELY DOWNSTREAM OF

MAIN CIRCUIT BREAKER. TIGHTLY TWIST FEEDER CONDUCTORS AND MAINTAIN

A MAXIMUM LENGTH OF 12 INCHES. COORDINATE CIRCUIT BREAKER RATING

AND ADDITIONAL FEEDER REQUIREMENTS WITH SPD MANUFACTURER.

8 PROVIDE EXISTING CIRCUIT BREAKER IN GENERATOR WITH KIRK-KEY

INTERLOCK DEVICE.
