This document provides guidance on selecting personal protective equipment (PPE) for various electrical work tasks. It includes the following: - Table 130.7(C)(9) outlines hazard/risk categories for different tasks on energized equipment, ranging from panelboards to switchgear. The table considers factors like voltage, fault current, and clearing time to determine the category. - Table 130.7(C)(10) specifies the required PPE, including rubber insulating gloves, insulating hand tools, protective clothing etc. based on the hazard/risk category determined in the previous table. - Notes provide additional guidance, such as on fault currents and clearing times for different voltage classes, and indicate that PPE is

(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

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.

General Notes (applicable to the entire table):
(a) Rubber insulating gloves are gloves rated for the maximum line-to-line voltage upon which work will be
done.
(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.
