KEY NOTES:
1. REPLACE WOOD POLE, 600A GANG-OPERATED SWITCH,
ARRESTERS, AND POLE GROUNDING.
2. REPLACE SINGLE POLE SOLID BLADE DISCONNECTS WITH
NEW 34.5kV SMU-20 POWER FUSE DISCONNECTS. ADD
WILDLIFE CAPS ON ARRESTERS.
3. INSTALL TWO 1/2” EHS STEEL GUY LEADS TO A COMMON
ANCHOR ATTACH THE PRIMARY GUY AT THE TOP
CROSSARM USING A 72” FIBERGLASS GUY STRAIN
INSULATOR ROD ATTACH THE SECONDARY GUY AT THE
NEUTRAL ATTACHMENT MAINTAIN A MINIMUM GUY LEAD
SLOPE OF 30º USE A POWER DRIVEN HELIX ANCHOR WITH A
20,000 LB PULL-OUT RATING.
4. INSTALL NEW RISER POLE INCLUDING 38kV TERMINATIONS, 34.5kV SMU-20 POWER FUSE DISCONNECTS. INSTALL 45'
CLASS 3 SOUTHERN YELLOW PINE POLE,
PENTACHLOROPHENOL PRESERVED. SET POLE AT 6.5'
DEPTH.
5. PROVIDE AND INSTALL NEW 10' X 8' X 7'H PRECAST
CONCRETE MANHOLE INCLUDING GROUNDING, RACKS,
RING, AND COVER ASSEMBLY. INSTALL NEW 6" - 4-WAY
DUCT BANK TOWARD RISER POLES, TURN UP TO STEEL
ELBOWS AT THE BASE OF EACH POLE. USE ONE OF THE
NEW TURN-UPS TO ROUTE CIRCUIT "B" FROM THE NEW
RISER POLE TO MH-1. CAP THE OTHER FOR FUTURE USE.
6. INSTALL A NEW 6' - 4-WAY DUCT BANK FROM MH-1 TO MH-2
AND TIE INTO THE EXISTING MANHOLE. IT IS ASSUMED
THAT THE FOUR CONDUITS NOW LEAVING MANHOLE MH-2
DO NOT EXTEND ALL THE WAY TO THE RISER POLES. IF IT
IS FOUND THAT THEY DO EXTEND TO THE EXISTING RISER,
INTERCEPT THEM AS CLOSE AS POSSIBLE TO MH-1 AND TIE
INTO THE EXISTING CONDUITS. IF THIS IS THE CASE, THE
GOVERNMENT WILL REQUIRE A DEDUCT CREDIT.

KEY NOTES:
1. REPLACE EXISTING MARINE FEDERAL CREDIT UNION
SECTIONALIZING SWITCH. DEMOLISH EXISTING CONCRETE
PAD, EXCAVATE SUB-BASE UNTIL LEVEL, AND ESTABLISH A
12" BASE OF CRUSHED STONE TO GRADE LEVEL TO
SUPPORT THE PRE-CAST PAD. MOVE NEW PAD LOCATION
SLIGHTLY TO THE EAST TO ADJUST EXISTING AND NEW
CONDUIT LOCATIONS TO THE LOCATIONS OF THE SWITCH
BUSHINGS.
2. MODIFY FENCE TO ALLOW ACCESS TO PRIMARY AND
SECONDARY TRANSFORMER COMPARTMENTS AT EXISTING
M.C.U. TRANSFORMER.
3. RECONFIGURE CABLES IN MANHOLE MH-4 PER MANHOLE
DIAGRAM DETAILS. RUN NEW TAPS FROM CIRCUITS "A" AND
"B" IN MH-4 AND CONNECT TO NEW LINE SIDE WAYS IN
SWITCH SS-2. RECONNECT EXISTING TAP TO MARINE
FEDERAL CREDIT UNION TO LOAD WAY OF NEW SWITCH.
CUT TAP TO LENGTH AS NEEDED AND INSTALL NEW LOAD
BREAK ELBOW CONNECTORS. IF THE CABLE DOES NOT
NEED TO BE SHORTENED, REMOVE EXISTING OUTER
ELBOW HOUSING, VERIFY CABLE CUT-BACKS, CLEAN
CABLE, AND INSTALL A NEW OUTER ELBOW HOUSING UNIT.
IF DAMAGE IS FOUND IN THE ELBOWS OR CABLE LENGTHS
WILL NOT WORK BACK, CONSULT DESIGNER OF RECORD
FOR GUIDANCE.
4. INSTALL ONE NEW 6" PVC CONDUIT FROM MH-4 TO NEW
SS-2 TO THE EAST OF THE EXISTING CONDUIT BANK.
COORDINATE LOCATION WITH THE ACTUAL SWITCH
BUSHING LOCATIONS SUCH THAT THE NEW CONDUIT
ALIGNS WITH THE EASTERNMOST LINE SIDE BUSHING
POSITION.

NOTE: CONDUIT
ARRANGEMENT VARIES.
GENERAL NOTES:
1. ALL QUANTITIES ARE ESTIMATES. CONTRACTOR
IS RESPONSIBLE FOR DETERMINING FINAL
QUANTITIES.
2. USE MATERIALS BY SPECIFIED MANUFACTURER
OR EQUIVALENT.
3. THE TOP OF THE DUCT BANK ENCASEMENT
SHALL BE A MINIMUM OF 30" BELOW GRADE.
4. SECURE THE CONDUIT IN POSITION BY DRIVING
A 36" LONG PIECE OF REBAR INTO THE TRENCH
WALLS. THIS WILL PREVENT THE CONDUIT FROM
RISING WHEN THE CONCRETE IS POURED.
5. POUR READY MIX CONCRETE WITH A STRENGTH
OF 2000 PSI AFTER 28 DAYS AND A MAXIMUM
AGGREGATE SIZE OF 3/8" AROUND THE DUCT
BANK. THE CONCRETE SHALL BE VIBRATED IN
ORDER TO FILL ALL OF THE SPACES AROUND
THE DUCTS. THERE MUST BE NO LESS THAN A 3"
ENVELOPE OF CONCRETE SURROUNDING THE
PERIMETER OF THE DUCT BANK.
6. FOLLOW NATIONAL ELECTRICAL CODE AND
NATIONAL ELECTRIC SAFETY CODE
REQUIREMENTS FOR MINIMUM BURIAL DEPTH
OF PRIMARY CABLE IN CONDUIT OR DUCT BANK.
NO PRIMARY CABLES SHALL BE BURIED AT LESS
THAN 30" BELOW GRADE WITHOUT SPECIFIC
GOVERNMENT APPROVAL.
7. THE TRENCH BOTTOM SHALL BE SMOOTH AND
FREE OF ROCKS AND DEBRIS. A 4" BED OF SAND
SHOULD BE ADDED IF THE BOTTOM IS ROCKY.
8. BACKFILL TRENCH WITH EARTH THAT IS FREE
OF VEGETATION, LARGE ROCKS, PIECES OF
PAVEMENT, AND OTHER FOREIGN MATTER.
9. INSTALL DUCT SPACERS EVERY 4' ALONG DUCT
ROUTE.
10. CONTRACTOR IS RESPONSIBLE FOR PLUGGING
EXTRA CONDUITS IN VAULTS.
DUCT BANK GROUNDING NOTES:
1. THE 4/0 BARE COPPER WIRE SHOULD BE
INSTALLED IN THE CONCRETE OF THE DUCT
BANK INSTALLATION FOR THE PURPOSE OF
LOWERING THE GROUND RESISTANCE IN THE
TRANSFORMER VAULTS AND MANHOLES.
THIS EMBEDDED CONCRETE METHOD WILL
OBTAIN LOWER GROUND RESISTANCES THAN
WIRE DIRECTLY BURIED IN THE SOIL OR A
LARGE NUMBER OF GROUND RODS. THE 4/0
BARE COPPER WIRE IS USED FOR THE PURPOSE
OF GROUNDING - NOT A SUBSTITUTE FOR THE
SYSTEM NEUTRAL.
2. CONSTRUCTION GUIDELINES:
A. INSTALL THE CONDUIT SPACERS AND THE
BOTTOM ROW OF PVCCONDUITS IN THE
TRENCH.
B. INSTALL THE 4/0 BARE COPPER WIRE
ALTERNATING THE WIRE FROM POSITION "A"
TO POSITION "B" IN THE CONDUIT SPACERS.
THE 4/0 BARE COPPER WIRE SHOULD BE
SAGGED WITH A 2" CLEARANCE FROM THE
BOTTOM OF THE CONCRETE DUCT BANK.
C. INSTALL THE REMAINING CONDUITS, CONDUIT
SPACERS AND CONCRETE IN THE
RECOMMENDED MANNER.
D. CONNECT THE 4/0 BARE COPPER WIRE TO
THE SYSTEM NEUTRAL IN EQUIPMENT AND TO
THE GROUND BUS IN THE MANHOLES. ALSO, A
DRILLED 1/2" HOLE IS REQUIRED IN THE
MANHOLE WALL FOR THE 4/0 BARE COPPER
WIRE. THE 1/2" HOLE AND WIRE SHOULD BE
WATERPROOFED WITH SEALING TAPE. THE 4/0
COPPER WIRE CAN BE SPLICED IN THE
VAULTS AND MANHOLES.
