STRUCTURE AND EQUIPMENT SERVED.

25 AVOID CUTTING AND BORING HOLES THROUGH CAVE WHEREVER POSSIBLE. OBTAIN PRIOR

APPROVAL OF CONTRACTING OFFICER WHEN CUTTING OR BORING IS NECESSARY AND

PERMITTED. EXISTING LOCATIONS, APPROVED FLOOR AREA LOCATION,STAIR STRUCTURES, OR

HANDRAILS SHALL BE USED OVER NEW LOCATIONS WHERE POSSIBLE.

ELECTRICAL VARIANCE AND WAIVERS

1 CODE INTENT: NEC 300.50 - TO PROTECT THE CABLE FROM DAMAGE

UNDERGROUND DIRECT BURRIED 0-600B CONDUCTORS SHALL BE INSTALLED

WITH MINIMUM COVER OF 24 INCHES.

WAIVER: 120V AND 240V CABLES SHALL BE ROUTED ON THE FLOOR THROUGH

THE CAVE AND WILL NOT BE BURIED IN THE CAVE OR ATTACHED TO THE CAVE

TO LIMIT RESOURCE DAMAGE. REFER TO SPECIFICATIONS DOCUMENT FOR

MORE INFORMATION.

CODE INTENT: TO ENSURE THAT LUMINAIRES ARE SERVICEABLE AND DO NOT

FALL AND HARM THE PUBLIC, NEC 410.3

WAIVER: THE LIGHT FIXTURES WILL BE SECURED WITH NON-METALLIC

JUNCTION BOXES AT THE BASE, AND AFFIXED TO THE RESOURCE UTILIZING

EXISTING HOLES FOR FASTENERS/HARDWARE TO THE EXTENT POSSIBLE AT

APPROVED LOCATIONS TO LIMIT RESOURCE DAMAGE. REFER TO

SPECIFICATIONS FOR MORE INFORMATION.

3 CODE INTENT: NFPA 101 - TO PROVIDE EMERGENCY LIGHTING TO A MINIMUM OF

1.0 AVERAGE FOOT-CANDLES ALONG THE PATH OF EGRESS, AND NO LOWER

THAN 0.1 FOOT-CANDLES ALONG THE PATH OF EGRESS. PROVIDE ILLUMININATED

EXIT SIGNAGE TO MARK PATH OF EGRESS

WAIVER: PARK RANGERS ARE EQUIPPED WITH FLASH LIGHTS TO ASSIST IN THE

EVACUATION OF VISITORS OUT OF THE CAVE IN THE CASE OF A POWER FAILURE

OR EMERGENCY SITUATION. REFER TO SPECIFICATIONS DOCUMENT FOR MORE

INFORMATION.

4 CODE INTENT: NEC 250 REQUIRES GROUND RESISTANCE TO BE ON THE ORDER OF

5-25 OHMS, WITH ADDITIONAL GROUND RODS/PLATES INSTALLED IF THIS LEVEL OF

GROUNDING IS NOT ACHIEVED IN ORDER TO PROVIDE A PATH TO GROUND WITH THE

LOWEST RESISTANCE POSSIBLE TO PROVIDE A FAST RESPONSE TO THE

OVERCURRENT PROTECTIVE DEVICES.

WAIVER: DUE TO THE NATURE OF THE WAY THAT THE CAVE DEVELOPED, THE CAVE

FLOOR IS ESSENTIALLY RUBBLE WITH A HIGH RESISTANCE. AS A RESULT,

CONNECTING ELECTRICAL EQUIPMENT TO A GROUND OF ANY NATURE PLACED

WITHIN THE CAVE IS NOT VERY EFFECTIVE. IN ADDITION, STANDARD METHODS FOR

REDUCING GROUND RESISTANCE INCLUDE CHEMICAL GROUNDS, GROUND RODS, OR

OTHER METHODS THAT WOULD DAMAGE OR COMPROMISE THE CAVE RESOURCE OR

ENVIRONMENT. WHILE THE GROUND RESISTANCE MAY NOT MATCH THAT OF

STANDARD BUILDING CONSTRUCTION, THE GROUNDING SYSTEM PROVIDED WILL BE A

GREAT IMPROVEMENT OVER THE EXISTING GROUNDING SYSTEM.

5 CODE INTENT: NEC 110.13 REQUIRES ELECTRICAL EQUIPMENT TO BE FIRMLY

SECURED TO A SURFACE ON WHICH IT'S MOUNTED SUCH THAT IT IS SERVICEABLE

AND WILL NOT FALL AND HARM THE PUBLIC.

WAIVER: LIGHTING ENCLOSURES MAY BE PLACED OFF TRAIL AND EQUIPMENT WILL

BE LOCATED OFF TRAIL WHERE THE PUBLIC IS NOT PERMITTED AND THE STAFF IS

AWARE OF THE HAZARD, SIMILAR CONDITION TO THE EXISTING CONDITION. REFER TO

THE SPECIFICATIONS DOCUMENT FOR MORE INFORMATION.

6 CODE INTENT: THE INTENT OF NEC 300.5 AND 300.50 - UNDERGROUND RACEWAYS

SHALL BE BURIED TO A MINIMUM DEPTH TO PROVIDE SUFFICIENT PROTECTION TO

BURIED RACEWAYS.

WAIVER: THE EXISTING 120V CABLE CONDITION IS ROUTED ON THE SURFACE OF THE

CAVE FLOOR, OFF TRAIL WHERE THE PUBLIC IS NOT PERMITTED AND CAVE

PERSONNEL RECEIVES TRAINING ON WHERE THE CABLES ARE AND HOW TO

PROTECT THE CABLES WHEN OFF TRAIL. REFER TO SPECIFICATIONS DOCUMENT FOR

MORE INFORMATION.

7 CODE INTENT: THE INTENT OF NEC 720.11 - LOW VOLTAGE CABLING SHALL BE BURIED

TO A MINIMUM DEPTH TO PROVIDE SUFFICIENT PROTECTION TO BURIED CABLING.

WAIVER: THE EXISTING CABLING CONDITION IS ROUTED ON THE SURFACE OF THE

CAVE FLOOR, OFF TRAIL WHERE THE PUBLIC IS NOT PERMITTED AND CAVE

PERSONNEL RECEIVES TRAINING ON WHERE THE CABLES ARE AND HOW TO PROTECT

THE CABLES WHEN OFF TRAIL. REFER TO SPECIFICATIONS DOCUMENT FOR MORE

INFORMATION.

POSSIBLE TO ROUTE NEW BRANCH CIRCUIT MULTICONDUCTOR CABLING TO

SWITCHES, LIGHT FIXTURES, AND RECEPTACLES. ADDTIONALLY, ROUTING

ADJUSTMENTS SHALL BE MADE FOR BETTER CONCEALMENT FROM DIRECT VIEW OF

WALKING TRAIL. ALL ROUTING ADJUSTMENTS AND MOUNTING POSITIONS SHALL BE

COORDINATED WITH CONTRACTING OFFICER.

CONDUCTOR SIZING FOR LIGHTING CIRCUITS:

THE FIRST WIRING SEGMENT FROM PANELBOARD TO SWITCHES SHALL BE 2#X, 1#XG,

WHERE "X" IS THE WIRE SIZE INDICATED IN THE CIRCUITING TABLE ON EACH PLAN

SHEET. FOR 3-WAY SWITCHING, PROVIDE 3#X,1#XG BETWEEN SWITCHES TO

ACCOUNT FOR THE TRAVELER WIRE. SOME SIZES INCREASED TO ACCOUNT FOR

VOLTAGE DROP. ALL DOWNSTREAM WIRING FROM SWITCHES TO LIGHT FIXTURES

SHALL BE 2#12,1#12G.

CONDUCTOR SIZING FOR RECEPTACLE CIRCUITS:

PROVIDE 2#8,1#8G TO ACCOUNT FOR VOLTAGE DROP.

EC SHALL PROVIDE PIGTAIL / PIN REDUCER CONNECTORS AND SPLICE BOX AS

REQUIRED FOR PROPER TERMINATION OF CONDUCTORS AT SWITCHES AND
