Notify the Engineer before performing work on the existing system. You may shu t down the system for alteration or removal. SECTION 87 ELECTRICAL SYSTEMS Where an existing Department underground facility is shown within 10 feet of any excavation, locate and field mark the facility before performing work that could damage or interfere with the existing facility. If a mandrel is used, it must be sized per the manufacture r's requirements. If an existing facility is within 2 feet of an excavation, determine the exact location of the facility by excavating with hand tools before using any power -operated or power -driven excavating or boring equipment. A vacuum excavator may be used if authorized. Notify the Engineer immediately if an existing facility is damaged by your activities:
1.Damaged existing traffic signal systems must be repaired or replaced within 24 hours. I f the system cannot be fixed within 24 hours or it is located on a structure, provide a temporary system until the system can be fixed.
2.Damaged existing lighting systems must be repaired or replaced by nightfall. If the system cannot be fixed by nightfa ll, provide a temporary system until the system can be fixed. If existing underground conduit is to be incorporated into a new system, clean it with a mandrel or cylindrical wire brush and blow it clean with compressed air. Limit the shutdown of traffic signal systems to normal working hours. Notify the local traffic enforcement agency before shutting down the signal. Place temporary W3 -1 and R1 -1 signs in each direction to direct traffic through the intersection during shutdown of the signal. Pla ce two R1 -1 signs for 2 -lane approaches. The signs must comply with part 2 of the California MUTCD . Cover signal faces when the system is shut down overnight. Cover temporary W3 -1 and R1 -1 signs when the system is turned on. If you work on an existing ligh ting system and the roadway is to remain open to traffic, ensure the system is in operation by nightfall. Replace detectors you damage within 72 hours, or the Department replaces them and deducts the cost. Work performed on an existing system not described is change order work. Do not use electrical power from existing highway facilities unless authorized. Maintain a minimum 48 -inch clearance for a pedestrian pathway when placing equipment. Except for service installation or work on service equipment enclos ures, do not work above ground until all materials are on hand to complete the electrical work at each location.

3.Be equipped to provide automatic start -stop operation with a 12 V starting system
4.Have generator output circuits that have overcurrent protection with a maximum setting of 15 A
5.Have a spark arrester complying with Pub Cont Code § 4442
87-20.02C Automatic Transfer Switches
An automatic transfer switch must provide:
1.Line voltage monitoring in the event of a power outage that signals the back -up power source to start
2.Start delay, adjustable from 0 to 6 seconds, to prevent st arting if the power outage is only momentary and a stop delay, adjustable from 0 to 8 minutes, to allow the back -up power source to unload
3.Transfer delay from 0 to 120 seconds to allow the back -up power source to stabilize before connecting to the load and retransfer delay from 0 to 32 minutes to allow the line voltage to stabilize SECTION 87 ELECTRICAL SYSTEMS
4.Mechanical interlock to prevent an application of power to the load from both sources and to prevent backfeeding from the back -up power source to the primary power source

87-20.03 Construction
87-20.03A General
Provide power and telecommunication services for temporary systems. Do not use existing services unless authorized. Commercial power must be 120 V(ac) or 120/240 V(ac) single phase. Make arrangements with the utility company for providing service. Protect the power sou rce in a locked enclosure. Provide keys for all locks to the Engineer. You may install conductors and cables:
1.In a conduit
2.Suspended from wood poles at least 25 feet above the roadway
3.Suitable for direct burial Install conduit outside the paved a rea at a minimum of 12 inches below grade for Type 1 and 2 conduit and at a minimum of 18 inches below grade for Type 3 conduit. Install direct burial conductors and cables outside the paved area at a minimum depth of 24 inches below grade. Install conduct ors and cables in Type 1, 2, or 3 conduit when mounted on wood poles to a height of 10 feet above the grade. Place conductors across structures in a Type 1, 2, or 3 conduit. Attach the conduit to the outside face of the structure . Mount the photoelectric u nit at the top of the standard or wood post. You may a bandon :
1.Conductors and cables in sawed slots
2.Underground conduit after removing conductors SECTION 87 ELECTRICAL SYSTEMS
