INSTALL COUPLING AND EXTEND NEW CONDUIT ON EXISTING FEEDER FROM SWITCHBOARD "T3." PULL IN NEW WIRING AS

SHOWN ON "SINGLE LINE DIAGRAM." FOR BID PURPOSES, ASSUME THAT EXISTING CONDUIT IS 4" RIGID GALV. STEEL.

PANELBOARD NOTE:

PHYSICAL SIZE OF NEW PANELBOARD SHOWN IS MEANT TO DEFINE THE INTENTION OF THE PANELBOARD REPLACEMENT.

OTHER SIZES MAY BE ACCEPTABLE, BUT CARE MUST BE TAKEN TO ENSURE THAT EXISTING CONDUCTORS WILL REACH

NEW CIRCUIT BREAKER TERMINALS. CIRCUIT BREAKERS LOCATIONS MAY HAVE TO BE ADJUSTED WITHIN THE

PANELBOARD TO ENSURE THAT THE EXISTING CONDUCTORS WILL REACH. ALL CONDUIT TERMINATIONS ON NEW

PANELBOARD WILL BE PROVIDED WITH GROUNDING BUSHINGS.

NEW PANELBOARD "PDP-1" - APPROXIMATE DIMENSIONS OF NEW BOX SHALL BE 26" W. X 6.5" D. X 83" H.

RECONNECT EXISTING EMPTY CONDUIT TO NEW PANELBOARD. FOR BID PURPOSES, ASSUME THAT EXISTING CONDUIT IS 2"

CIRCUIT BREAKER NOTE:

EXISTING FUSE SIZES HAVE BEEN VERIFIED IN THE EXISTING FUSIBLE PANELBOARDS ONLY WHERE EXISTING FUSIBLE

SWITCH DOORS COULD BE OPENED WHILE THE SWITCH WAS ENERGIZED. FUSE SIZES HAVE NOT BEEN VERIFIED WHERE

THE SWITCH DOORS COULD NOT BE OPENED. THE CONTRACTOR SHALL SCHEDULE A POWER OUTAGE PRIOR TO

ORDERING THE NEW REPLACEMENT CIRCUIT BREAKER PANELBOARDS SO THAT ALL FUSIBLE SWITCH DOORS CAN BE

OPENED AND ALL FUSES SIZES CAN BE VERIFIED. THE CONTRACTOR SHALL PROVIDE NEW CIRCUIT BREAKERS IN THE

NEW PANELBOARDS WHICH ARE SIZED TO MATCH THE EXISTING FUSE SIZES. THE AS BUILT DRAWINGS PROVIDED AT

THE END OF CONSTRUCTION SHALL REFLECT THE EXACT CIRCUIT BREAKER SIZES.
