NFPA 70E (130.4)

(A) Shock Hazard Analysis – A shock hazard analysis or Arc Flash Analysis shall determine the voltage to which personnel will be exposed, the approach boundary requirements, and the personal protective equipment necessary in order to minimize the possibility of electric shock and personnel.

(B)  Shock Protection Boundaries – The shock protection boundaries identified as limited approach, restricted approach, and prohibited approach boundaries, shall be applicable where approaching personnel are exposed to energized electrical conductors or circuit parts.

NFPA 70E Table 130.4 (C)(a) shall be used for the distances associated with various AC system voltages.

NFPA 70E Table 130.4 (C)(b) shall be used for the distances associated with various DC system voltages.

(C) Approach to Exposed Energized Electrical Conductors or Circuit Parts Operating at 50 Volts or more – No qualified person shall approach or take any conductive objects closer to exposed energized electrical conductors or circuit parts operating at 50 volts or more than the restricted approach boundary set forth in Tables 130.4 (C)(a) or (b) unless any of the following apply:

(1) The qualified person is insulated or guarded from the energized electrical conductors or circuit parts operating at 50 volts or more. Insulating gloves or insulating gloves with sleeves are considered insulation only withregard to the energized parts upon which work is being performed. If there is a need for an uninsulated  part of the workers body to cross the prohibited approach boundary, a combination of 130.4(C)(1), 130.4(C)(2), and 130.4(C)(3) shall be used to protect the uninsulated body parts.

(2) The energized electrical conductors or circuit part operating at 50 volts or more are insulated from the qualified person and from any other conductive object at a different potential.

(3) The qualified person is insulated from any other conductive object as during live-line bare hand work.

(D) Approach by Unqualified Persons – Unless permitted by 130.4 (D)(2), no qualified person shall be permitted to approach nearer than the limited approach boundary of energized conductors and circuit parts.
