At what voltage is arc flash PPE required?
Each piece of equipment operating at 50 volts or more and not put into a deenergized state must be evaluated for arc flash and shock protection.
What PPE should be worn when testing for voltage on electrical conductors?
Face shields with the appropriate arc flash rating (in cal/cm2) shall be used for electrical work. Safety glasses or goggles must always be worn underneath face shields. Nonconductive safety glasses or goggles are to be worn. Eye protection may be tinted to protect from flash injury.
What is the arc flash boundary for 480 volts?
12 inches
The earlier mentioned voltages of 208, 220, 240, 277, 380, and 480 volts AC have a restricted boundary of 12 inches.
What PPE does an electrician need?

What level of PPE is needed when the highest degree of respiratory protection is needed but a lower level of skin protection can be used?
Level B
Level B: Level B PPE should be worn when an employee needs the highest level of respiratory protection, but less skin and eye protection is necessary. This protective ensemble is used on initial site entries where hazards may not have been fully identified yet.
What is the highest voltage protection that electrical protective gloves provide?
Similarly, gloves also are rated for use in applications where protection against higher voltages is required. Class 1 gloves can be used up to 7,500 volts AC, Class 2 up to 17,000 volts AC, Class 3 up to 26,500 volts AC, and Class 4 up to 36,000 volts AC.
