i have used nylon wall-mates to secure the tape so as to be non-conductive.
an energiser is powered by a 12v battery and the hotwire connects to the energiser.
i can touch the weldmesh and no tingles.... so-far so good. the birds still hang on the wire as usual with no ill effect....i guess there is no grounding/earth to complete a circuit anyway.
the gap between the hot-wire and framework is small approx 1cm, the tape is tight and does not flap or sag. much less than this and it will spark across, especially at the corners.
so far i have had good results though a daily walk around is required to remove leaves and dead sugar ants(they "click" really loud) and the odd green frog.
i have yet to see a mouse or rat encounter the tape but feel my last line of defense will hold up!
i think it is true what others have said regarding animals being aware of the electric fence because my 2 dogs wont go near it and they would cock their legs on just about anything if it stood still long enough, so the rodents/snakes may just stay away....which suits me. time will tell.
