  1. 1. 130.7 ARTICLE 130 (9) Selection of Personal Protective Equipment When Required for Various Tasks. Where selected in lieu of the ffi analysis of 130.3(ffi)(1), Table 130.7(C)(9) shall be used to determine the hazardlrisk category ffi The assumed maximum short-circuit current capacities and maximum fault clearing times for various tasks are listed in the notes FPN No. 3: ffi circuit parts that operate at less than 50 volts w to be de- energized to satisfy an "electrically safe work condition." Consideration should be given to the capacity of the source, any overcurTent protection between the energy source and the worker, and whether the work task related to the source operating at less than 50 volts increases exposure to elec- trical burns or to explosion from an electric arc.

(b) Insulated and insulating hand tools are tools rated and tested for the marimum line-to-line voltage uporl which work will be done. and are manufactured and tested in accordance gith ASTM F 1505, Standard Specification for Insulated and Insulating Hand Tools. (c) Y = yes (required), N = no (not required). (d) For systems rated less than 1000 volts. the fault currents aad upstream protective device clearing times are based on an 18 in. working distance. (e) For systems rated 1 kV and greater, the Hazard/Risk Categories are based on a 36 in. working distance. (f) For equipment protected by upstream current limiting fuses with arcing fault current in their current limiting range (Vz cycle fault clearing time or less), the hazard,/risk category required may be reduced by one number. Specific Notes (as referenced in the table): 1. Maximum of 25 kA short circuit current available; maximum of 0.03 sec (2 cycle) fault clearing time. 2. Maximum of 65 kA short circuit current available; maximum of 0.03 sec (2 cycle) fault clearing time. 3. Maximum of 42kA short circuit current available; maximum of 0.33 sec (20 cycle) fault clearing time. 4.
