WebAs with ungrounded systems, during a ground fault the line-to-ground voltage of the unfaulted phases increases (from line-to-neutral to line-to-line voltage), which increases the probability of a second ground fault because of increased stress on insulation. The faulted equipment should be repaired or replaced as soon as practicable. WebA ground fault circuit interrupter (GFCI), or Residual Current Device (RCD) is a type of circuit breaker. This type shuts off electric power (or breaks the electrical circuit ), to protect people from an electric shock caused when …
