Disadvantages of RCD: RCD don't provide protection against Current Overload. When an RCD trips due to fault current greater than the RCDs kA rating, the RCD could become damaged and may not pass an RCD test. In thiscase, audit revealed that there were more deaths in Bed 3 than the others, and more on Tuesdays than other days of the week.
