1. Scope
1.1 This specification covers portable, live-line tool-supported two-pole phasing testers to be used on AC electrical systems. 1.2 Two Types of phasing testers are provided and are designated as Type I Resistive and Type II Capacitive. 1. 3Two Styles of phasing testers are provided and are designated as Style A Numerical and Style B Audible/Visual. 1.4 The use and maintenance of these high voltage phasing testers and any necessary insulated tool handles are beyond the scope of this specification. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE 1 Except where specified, all voltage defined in this specification refers to phase-to-phase voltage in a three-phase system. Phasing Testers covered by this specification may be used in other than three-phase systems, but the applicable phase-to-phase or phase-to-ground (earth) voltages shall be used to determine the operating voltage.
