2. NFPA 70E - Wikipedia

   en.wikipedia.org/wiki/NFPA_70E

   Key principles covered are JSA/JHA/AHA procedures to ascertain shock protection boundaries, arc flash incident energy expressed in calories/cm2, lockout-tagout, and personal protective equipment. While the various OSHA, ASTM, IEEE and NEC standard provide guidelines for performance, NFPA 70E addresses practices and is widely considered as the ...

3. Arc flash - Wikipedia

   en.wikipedia.org/wiki/Arc_flash

   Light and current based protection can be set up with dedicated arc-flash protective relays, or by using normal protective relays equipped with an add-on arc-flash option. One of the most efficient means to reduce arcing time is to use an active arc flash mitigation device, e.g., an ultra-fast earthing switch (UFES).

4. IEEE 1584 - Wikipedia

   en.wikipedia.org/wiki/IEEE_1584

   IEEE 1584-2018 is an update to IEEE 1584-2002 and was developed to help protect people from arc-flash hazard dangers. The predicted arc current and incident energy are used in selecting appropriate overcurrent protective devices and personal protective equipment (generally abbreviated as PPE), as well as defining safe working distance. Since ...

   The flash-point is the temperature at which the material will generate sufficient quantity of vapor to form an ignitable mixture. The flash point determines if an area needs to be classified. A material may have a relatively low autoignition temperature yet if its flash-point is above the ambient temperature, then the area may not need to be ...

7. Arc-fault circuit interrupter - Wikipedia

   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires.
