Maybe, maybe not. 29mA for even a short period would kill some people. The line had to be drawn somewhere, and the 30mA requirement for RCDs relates to the fact that a shock of 30mA or above carries a 'significant' risk of death - but a risk of death exists at less than 30mA in healthy people, and at a lot lower currents than that in those with certain diseases. Conversely, there's no guarantee that currents of 30mA (or a lot higher) will kill.So if you received a 29mA shock for god knows how long you'd walk away absolutely unharmed would you?
