Units shall have adjustable light level and off-time. For academic buildings, or similar buildings conducting sound sensitive research, the sound sensors shall be switched off and disabled.
C. Provide wall plates equal to building standard on all switches and receptacles. Where no standard exists, provide specification grade stainless steel (type 302).
D. Where there are multiple devices in one location, devices shall be ganged under one cover plate. All wall switches shall be flush mounted, where applicable.
E. Receptacles shall be mounted 18" above finished floor, on strike side of door, unless otherwise indicated.
F. Wall switches shall be mounted 48" above finished floor, on strike side of door, unless otherwise indicated..
2.6 CIRCUIT BREAKERS
A. All new circuit breakers shall match existing in style, manufacturer and interrupting rating for panel in which they are being installed, unless otherwise indicated. When multiple breakers in a source have differing interrupting ratings the highest rated breakers shall be used to match new equipment.
PART 3 - EXECUTION
3.1 LOAD BALANCE
A. The electrical contractor shall balance the loads on the three phases in the electrical panel board in which he does work insofar as physically possible, and report each panel loading to the engineer.

3.2 CIRCUIT BREAKER TESTING/SETTING
A. Feeder circuit breakers shall be tested by an independent testing firm with 10 years experience prior to installation.
B. Tests shall be performed at specified trip setting to insure proper operation.
C. Results of all tests shall be furnished to the owner for record.
D. Verify final trip settings for adjustable or interchangeable circuit breaker elements. Instantaneous settings shall be minimum unless otherwise noted.
3.3 GENERAL WIRING TESTS
A. At the time of final inspection and test, all wiring and connections throughout the renovation areas must be completed, devices and equipment properly operating, lighting fixtures installed, and power and lighting circuit and control wiring clearly identified with approved tags ready for acceptance. Each system shall test free from short circuit and grounds.
B. Insulation resistance for low voltage cables and wiring shall be performed at 1000 volts DC for one (1) minute. When insulation resistance must be determined, switchboards, panel boards, fuse holders, switches, and overcurrent devices shall be in place, and the insulation resistance when tested at 1000 volts DC shall be no less than 100,000 ohms for #14 and #12 wire and 250,000 ohms for #10 wire and larger. Conceal cables in finished walls, ceilings, and floors unless otherwise indicated.
3.4 OPERATIONS TESTS
A. Each piece of electrical equipment, including lighting fixtures, motors, and controls shall be operated continuously for a minimum test period of one hour.
B. Demonstrate by operating equipment that circuits and devices are in good operating condition. Each item of control equipment shall be operated a minimum of five times. Demonstration shall be performed after wiring tests. Tighten electrical connectors and terminals according to manufacturer's published torque-tightening values. If manufacturer's torque values are not indicated, use those specified in UL 486A-486B.
3.5 MECHANICAL SYSTEM ADJUSTMENT AND TESTING
A. Be present during adjustment period and final testing of mechanical systems. Take readings necessary to ensure that electrical systems are operating properly. Test for mechanical work are detailed under DIVISION 23.
B. Take ampere readings with true RMS reading ammeter at each electrical component, such as motor and compressors, to determine proper operation.
C. Record readings and submit them to the engineer for review.

3.6 LABELING
A. Label all new disconnects, starters, motors, feeder boxes, in a manner acceptable to the engineer. Provide updated panel schedules in all panel boards within the scope of work. Label feeder raceway along path to facilitate tracing with source, destination, voltage, and isolating device. Paint all new fire alarm raceway red.
B. All manufacturer's nameplates shall be kept clean and free of paint.
C. Data/Communications wiring done under this contract shall be recorded on cable management drawings. Each outlet shall be assigned a number which shall be keyed to its punch down location. Identify and color-code conductors and cables according to Section 260553 "Identification for Electrical Systems."; or, by Engineer of University IT Department directions and standards.
