PART 3 EXECUTION
3.1 INSTALLATION
A. VERIFY EXACT LOCATION, mounting height and usage of each outlet box. Boxes shall be set plumb and square with building walls, floors, ceiling and other elements. Maximum tolerance shall be 1/16 inch.
B. MOUNT outlet boxes flush in areas other than mechanical rooms, electrical rooms, and above removable ceilings.
C. ADJUST position of outlets in finished masonry walls to suit masonry course lines.
D. DO NOT INSTALL boxes backtoback in same wall. Coordinate cutting of masonry walls to achieve neat openings for boxes. Use rotary cutting equipment to cut masonry work for installation of electrical fittings.
E. LOCATE boxes in masonry walls so that only a corner need be cut from masonry units.
F. DO NOT USE sectional or handy boxes unless specifically requested.
G. FOR BOXES MOUNTED in exterior walls make sure that there is insulation behind outlet boxes to prevent condensation in boxes.
H. FOR OUTLETS MOUNTED above counters and splash backs, coordinate location and mounting heights with builtin units. Adjust outlet mounting height to agree with required location for equipment served.
I. SHEET STEEL BOXES: Do not set where fixture and device requires cast or otherwise special outlet boxes.
J. FLOOR, WALL AND CEILING OPENINGS:
1. REQUIRED OPENINGS: Coordinate with Contractor in arranging for openings required in floors, walls or ceilings, such as large floor boxes, recessed light fixtures, and panels.
2. PLASTER RINGS OR TRIMS: Unless otherwise indicated, Electrical Subcontractor shall provide plaster rings or trims for openings used by him.
PART 4 LOCATION
4.1 LOCATIONS OF OUTLETS
A. STUDY Architectural, Structural and Mechanical Drawings as well as any Drawings of existing structures, prior to roughin.
B. VERIFY exact mounting heights and exact locations for outlets. Adjust actual heights and locations to minimize masonry cutting by utilizing joints in masonry as much as possible.
C. LOCATE OUTLETS AND EQUIPMENT so as to avoid interference with building trim, door swings, mechanical and other equipment, sprinkler heads, and ducts.
D. STUBBING ARRANGEMENTS AND OUTLET ARRANGEMENTS: Verify for equipment connections, to be proper for equipment installed.
E. OUTLETS: Align, group and otherwise arrange in pleasing and logical arrangement with respect to architectural elements.
F. GANG UP OUTLETS shown together on Drawings unless interconnecting conduit is indicated.
G. INSTALL OUTLETS flush and plumb unless otherwise noted. Long axis of a "Gang" shall be vertical except where the word "Horizontal" is noted, or unless available room dictates that outlet be set horizontally.
