<div>There definitely can be mA of leakage to ground, even if its not

one will not present any danger unless you are referenced to its

<div style="margin: 0px;">Except of course, if there is more
leakage (capacitive) from one ungrounded wire to ground than the other
ungrounded wire to</div>
<div style="margin: 0px;">ground. <span
class="Apple-converted-space"> </span>You may still feel a tingle...
The higher the voltage, given similar leakage, the higher the
tingleage. (is that a real word?)</div>
<div style="margin: 0px;">I am more apprehensive about touching
ungrounded and live things (although sometimes I do). People have a
larger area and</div>
<div style="margin: 0px;">therefore a higher capacitance than birds
do.</div>
<div style="margin: 0px; min-height: 14px;"><br>
</div>
<div style="margin: 0px;">This applies for AC (mainly) of course.</div>
