A high impedance fence charge will work because its output is 10,000 to 20,000 volts DC with very small amperage. It will require the high voltage to get through the bird’s tough skin on its foot. Don’t need high amps unless you want to fry them. The high voltage will knock their socks off.
Hot and Ground wires will need to be not too close or it’ll spark. I’d guess 3/4” separation.
Trying this with 110 or 240 vac is damned dangerous and probably not effective on the birds.
High voltage and low low amperage is the way to go. High amperage even at 120v will be ineffective and possibly very dangerous. When I was a growing up a neighbor went to jail when his “electric fence” which was hooked up to line current killed a kid.
The thread reminds me of locker room talk... I hope that VA Voter doesn't follow any of the dangerous advice. It doesn't make any sense to use something dangerous when a safe and effective option is available for relatively low cast.
