# E3.0 - SPECIFICATIONS

## SECTION 16010 - BASIC ELECTRICAL REQUIREMENTS

### 1) PART 1 GENERAL

#### a) POWER AND CONTROL WIRING

* i) Provide power system conduit and wiring to mechanical equipment.  Controls system conduit and wiring for mechanical systems is included under Division 15.  “Power” wiring includes line voltage wiring from distribution apparatus to disconnecting means provided or installed under this section, and from such disconnecting means to motors, and to terminal boxes of 'package' equipment.  “Controls” wiring includes wiring, regardless of voltage, which provides start-stop control for mechanical equipment and/or which is used to monitor functions of mechanical systems.  Where line voltage wiring is extended from a local disconnecting means to relays, thermostats, by-pass timers, starter coils or the like, or from mechanical control panels or motor control centers to control devices, such extensions are considered “control” wiring.

#### b) MOUNTING HEIGHTS

* i) Mounting heights and locations: verify the exact location of equipment with architect prior to installation.  Wall mounted devices requiring operational access shall be mounted a minimum of 15 inches above finished floor to bottom of device and a maximum of 48 inches above finished floor to top of device.  Visual alarms shall be mounted not less than 80 inches to the bottom or 96 inches to the top of the device.

#### c) REGULATORY REQUIREMENTS

* i) Conform to:

    * (1) NFPA-70 - National Electric Code.

* ii) Comply with the current applicable codes, ordinances, and regulations of the authority or authorities having jurisdiction, the Owner's insurance underwriter, and applicable base building standards.

* iii) When conflict exists between two or more governing codes, comply with the stricter requirement.

* iv) Obtain permits, and request inspections from authority having jurisdiction.

#### d) PROJECT/SITE CONDITIONS

* i) Install Work in locations shown on Drawings, unless prevented by Project conditions.  Coordinate installation of work in available space with work furnished under other Divisions.

### 2) PRODUCTS

* a) Where manufacturer's model or series numbers are specified or shown, these indicate generally acceptable types required.  Furnish products which comply with all requirements, as specified or shown.

* b) When more than one unit of the same class of equipment is required, provide units produced by a single manufacturer.

### 3) TESTS

* a) Furnish test equipment, facilities, and technical personnel required to perform field tests.

* b) At completion of job, check voltage at several points of utilization on the system.  Energize all loads installed.

### 4) CLEANING

* a) Clean all fixtures and equipment at the completion of the project.  Wipe clean exposed lighting fixture reflectors and trim pieces with a non-abrasive cloth just prior to occupancy.

### 5) RECORD DRAWINGS

* a) Upon completion of the Work, deliver to Architect and up-to-date set of “as-built” record drawings on a reproducible medium including AutoCAD.

### 6) DEMOLITION

* a) Remove, relocate, and reroute existing electrical equipment to facilitate new construction or remodeling work.

* b) Examine the site to observe and note existing conditions prior to submitting a bid.

* c) Schedule demolition in advance.  Schedule work to avoid disruption of normal operations.

* d) Reconnect circuits serving equipment required to remain in service to other panelboards, motor control centers, or other appropriate distribution equipment.  Provide additional panelboards, motor control centers, or other appropriate distribution equipment where there is insufficient available capacity in remaining existing equipment for reconnection.

* e) Remove existing conduit and wire back to panelboard, motor control center, or other distribution source.

* f) Where a circuit is interrupted by removal of a device or fixture from that circuit, provide additional conduit and wire to restore service to the remaining devices and fixtures on that circuit.

* g) Electrical equipment to be removed that is in good working order shall be carefully removed and offered to the Owner. Items rejected by the Owner shall be removed from the project site and properly disposed of.
