With electric fencing rule #1 is always have a good ground. Put your grounding rod in moist earth and keep any grass or other vegetation from touching the wires. This will short the fence out and then the fence won't work. For 5 strands, be sure to buy a charger big enough to power the 5 strands. I personally like to buy twice the power for the amount of wire I have, say 5 miles of wire get a 10 mile charger.
