COMMON POINT GROUND
Per ANSI/ESD S6.1, Grounding section 4.1.1 “Every element to be grounded at an ESD protected station shall be connected to the same common point ground.” ESD Handbook ESD TR20.20 section 5.1.3 Basic Grounding Requirements “The first step in ensuring that everything in an EPA is at the same electrical potential is to ground all conductive components of the work area (worksurfaces, people, equipment, etc.) to the same electrical ground point. This point is called the common point ground. The next step in completing the ground circuit is to connect the common point ground to the equipment ground (third wire, green).”
General Grounding Guidelines
1. ANSI/ESD S20.20 requires that all conductors in an ESD protected area, including personnel, must be grounded. 2. The ESD ground must be tied directly to and at the same potential as the building or “green wire” equipment ground. 3. Per ANSI/ESD S20.20, the ESD control program can in no way replace or supercede any requirements for personnel safety. Ground fault circuit interrupters (GFCI) and other safety protection should be considered wherever personnel might come into contact with electrical sources. 4. All electrical outlets should be verified for proper wiring ­ configuration, resistance or impedance and GFCI function when the mat is installed and periodically thereafter.

Designation:A 363–03Standard Specification forZinc-Coated (Galvanized)Steel Overhead Ground Wire Strand 1This standard is issued under the fixed designation A 363;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon (e )indicates an editorial change since the last revision or reapproval.1.Scope*1.1This specification covers high-strength,extra-high-strength,and utilities grades of concentric lay steel wire strand composed of three wires or seven wires with Class A,Class B,or Class C zinc coatings specifically intended for use as overhead ground wires or static wires for electric power transmission lines.1.2The values stated in inch-pound units are to be regarded as the standard.The SI units given in brackets are for information only.2.Referenced Documents 2.1ASTM Standards:A 90/A 90M Test Method for Weight

definitions of terms used in this specification,refer to Terminology A 902.4.Ordering Information4.1Orders for strand purchased under this specification shall include the following information:4.1.1Quantity of each size,4.1.2Size and grade of strand (Table 1),and4.1.3Class of zinc coating (Section 11and Table 2).4.1.4ASTM designation and year of issue.5.Materials and Manufacture5.1The base metal shall be steel produced by any commer-cially accepted steel making process and shall be of such quality and purity that when drawn to the size of wire specifiedand coated with zinc,the finished strand will have the properties and characteristics prescribed in this specification.5.2The slab zinc when used for the coating shall be any grade of zinc conforming to Specification B 6.6.Stranding6.1The strand shall have a left lay with a uniform pitch of not more than 16times the nominal diameter of the strand.A left lay is defined as a counter-clockwise twist away from the observer.Stranding shall be sufficiently close to ensure no significant reduction in diameter when stressed to 10%of the minimum breaking strength.7.Preforming Strand7.1Preformed strand shall be supplied when so specified by the purchaser.Strand is preformed when the component wires are set to the helical form which they assume in the product by any means of process other than by merely laying them about the strand core.8.Breaking Strength and Weight8.1The approximate weight per unit length of strand and the minimum breaking strength of the finished strand shall be as specified in Table 1.8.2A test in which the breaking strength is below the minimum specified and which may have been caused by the slipping of the specimen in the jaws of the testing machine,by breaking within the jaws or within 1in.[25.4mm]of the jaws,or by the improper socketing of a specimen shall be disre-garded and another sample from the same coil or reel shall be tested.9.Elongation9.1The elongation of the strand in 24in.[610mm],determined as specified in 9.2,shall be not less than 5%for the high-strength and for the 5⁄16-in.[7.94-mm],3-wire utilities grades,and 4%for the extra-high-strength and for the "-in.[9.52-mm],7-wire Utilities grades.9.2The elongation shall be measured as the percentage increase in separation between the jaws of the testing

zinc-coated wire shall be uniform in diameter and shall be free from splints,scales,inequalities,flaws,and other imperfections not consistent with good commercial practice. The coating shall be continuous and reasonably uniform. 16.Sampling16.1The number of samples to be taken shall be determined by lot size as follows:Lot Size Number of Samples1to3reels1from each reel4to30reels3min31reels or greater4min16.2Each sample taken shall be subjected to all tests prescribed in Sections6,8,and9.16.3In addition to the strand testing in16.2the individual wires from the strand samples shall be tested for compliance with Sections10,11,12,and14.Select all three wires in three-wire strand,and four of the wires in seven-wire strand. Individual wire samples selected for compliance to Section14 shall be discarded if any distortion of the wire occurred during the stranding operation.16.4Instead of testing the wires from the completed strand in accordance with16.3,the producer may elect to establish compliance with Sections10,11,12,and14of this specifica-tion by tests made on the wires prior to stranding,unless otherwise stipulated by the purchaser.However,if the producer makes this election,the purchaser shall still reserve the right to test wires from the completed strand for compliance.TABLE1Physical Properties of

hot galvanizing,are not perfectly smooth and devoid of irregularities.If the tolerances shown above are rigidly applied to such irregularities that are inherent to the product,unjustified rejections of wire that would actually be satisfactory for use could occur.Therefore,it is intended that these tolerances be used in gaging the uniform areas of the galvanized wire.TABLE2Minimum Weights of
