neighbors who've been here for 20+ years say they've never seen deer during
the hours when kids would be out playing and might approach the garden. So,
I thought I'd probably put the electric fence on a timer. I understand that
the fence is unlikely to harm a person

I wouldn’t wory about those kids unless one of them has a pacemaker. My
small unit runs at 1000 Volts and the big one at 5000, but the current is
miniscule. Touching the fence is about equivalent to the shock you get when you
scuff your feet on a rug. That static electricity jolt, by-the-way is about
50,000 volts, but the only way you can get hurt is if you happen to be picking
up a gas can.
