what is the difference betwteen overcurrent and short
circuit fault?

Answer Posted / mahesh katakdhond

overcurrent means just harm equipment slowaly (20to50percent greater than actual current)

shortcicuit means harm suddenly on equipment(it will some multipal value to actual current(4,5,6,7,....*actual current)
