WebJun 20, 2024 · Understand basic features when selecting and specifying electrical distribution equipment. Know the types of overcurrent protection devices, such as circuit breakers and fuses, and switchgear as it is outlined in UL 1558. We are starting out with an excerpt directly from Article 90, the introduction to NFPA 70: National Electrical Code. WebArcing Fault: An arcing fault results from a gap between two electrodes (such as loose wire on a terminal block). Arc welding is a common example of the practical application of the heating due to arcing. The power supply for an arc welder can supply very high currents that flow through the welding rod and the metal pieces being welded.

For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker. … See more A transient fault is a fault that is no longer present if power is disconnected for a short time and then restored; or an insulation fault which only temporarily affects a device's dielectric properties which are restored … See more Asymmetric fault An asymmetric or unbalanced fault does not affect each of the phases equally. Common types of asymmetric fault, and their causes: See more A ground fault (earth fault) is any failure that allows unintended connection of power circuit conductors with the earth. Such faults can … See more Where the system voltage is high enough, an electric arc may form between power system conductors and ground. Such an arc can have a relatively high impedance (compared to the … See more A persistent fault is present regardless of power being applied. Faults in underground power cables are most often persistent due to mechanical damage to the cable, but are sometimes transient in nature due to lightning. See more One extreme is where the fault has zero impedance, giving the maximum prospective short-circuit current. Notionally, all the conductors are considered connected to ground as if by a metallic conductor; this is called a "bolted fault". It would be … See more Realistically, the resistance in a fault can be from close to zero to fairly high relative to the load resistance.
