Wet Location Body Resistance

Legh Richardson:

You can usually half the body resistance, which, in effect corrolates to half the shock voltage when the body is wet, as Mike has stated. These safety measures are usually achieved by supplementary bonding and/or RCDs, reg 415.


RCDs seem to be the preferred method of protection today. See this link below.

Right, though if supplemental bonding is not present, the CPC & ADS should be the first line of defense followed by RCD. RCDs are more likely to fail than a CPC.
