Part 3           EXECUTION

3.01.                      Installation of Wiring Devices:

A.                  Interior Locations: In finished walls, install each device in a flush mounted box with washers as required to bring the device mounting strap level with the surface of the finished wall.  On unfinished walls, surface mount boxes level and plumb.

B.                  Mounting Heights: Measure locations of wall outlets from the finished floor to the center of the outlet box.  Adjust boxes so that the front edge of the box shall not be farther back from the finished wall plane than 1/4-inch.  Adjust boxes so that they do not project beyond the finished wall. Unless otherwise noted, height above finished floor shall be as follows:

1.                   Receptacles                        18  Inches from floor

2.                   Toggle Switches                  48  Inches from floor

C.                  Receptacles:

1.                   Ground each receptacle using a grounding conductor, not a yoke or screw contact.

2.                   Install receptacles with connections spliced to the branch circuit wiring in such a way that removal of the receptacle will not disrupt neutral continuity and branch circuit power will not be lost to other receptacles in the same circuit.

3.02.                      Installation of Wall Plates:

A.                  General - Plates shall match the style of the device and shall be plumb within 1/16-inch of the vertical or horizontal.

B.                  Interior Locations, Finished Walls: Install non-metallic plates so that all four edges are in continuous contact with the finished wall surfaces.  Plaster filling will not be permitted.  Do not use oversized plates or sectional plates.

C.                  Interior Locations, Unfinished Walls: Install stainless steel or cast metal cover plates.

D.                  Exterior Locations: Install cast metal plates with gaskets on wiring devices in such a manner as to provide a rain tight weatherproof installation.  Cover type shall match box type.

E.                  Future Locations: Install blanking cover plates on all unused outlets.

3.03.                      Tests:

A.                  Receptacles:

1.                   Test receptacles for blade and ground plug tension prior to installation.  Do not install any receptacle having less than 16 oz. individual blade retention.

2.                   After installation of receptacles, energize circuits and test each receptacle to detect lack of ground continuity, reversed polarity, and open neutral condition.
