    Safety of Using Adiabatic Method?

    I'm thinking, and while I could be wrong, is the adiabatic method a possible latent safety hazard? As well as undersized CPCs on circuits 32 amps and under? Normally DNO sources are strong with relatively high PFC, and we have a known Ze value. However, should someone bring a portable...

    Table 710

    Right, but I'd imagine there is some specific table in one of the IEC standards. Basically I want to quantify body impedance in 3 environments: 1) Dry (general indoor locations) 2) wet (bathrooms, kitchens, unfinished basements, garages, exteriors) 3) special locations (pools, spays, medical...

    Table 710

    Does anyone know what body resistance this table is based on? And what IEC standard is it derived from?

    In theory the voltage gradient would be worse in fresh water than salt water.

    I'd argue the UK public is among the most educated on earth. If given listed appliances with a note "do no use in shower or bathtub" I'd trust everyone would follow through. At least they do in the US.

    Rain vs wet hands is a bit different, but, at the same time, rain water has a resistance of 20,000 ohms.

    Are wet hands really going to bring voltage out of the dryer or drill?

    How would a listed hair dryer be dangerous when its double insulated? Having an outlet by the sink and within two feet of the shower is common and no one I know has ever gotten hurt. A typical example:

    Thats my point, bath sockets all over the world, including in the litigation driven USA.

    How would they get killed with listed appliances and an RCD?

    I'd argue not having a socket in the bathroom increases the odds of an extension lead being used. I personally see no issue with a socket reasonably placed outside the tub perimeter.

    What stops someone from taking power from the hall receptacle?

    It does on the basis that BS7671 fails to require a faster disconnection time. IEC61200-413 assumes 200 ohms in wet locations and allows for a maximum of 0.17 seconds.

    Still doesn't make sense. The switch plate, screws and toggle would not be energized.
