LOL - You would not be hooking a fence charger to your chickens hardware cloth - chickens would get zapped and fence would be too weak to keep out bears. You need to have a STRONG Fence Charger run by electric or solar/battery, steel post, insulators, fence wire and underground insulated wire - which will hook up to the ground on fence charger and to ground wire and to 3 8' ground rods (each put in the ground 6'+ deep and space 12-15' apart) ground rods can be underneath your elecric fence.
Normally you would alternate hot wires and ground wires. below is simple diagram.
Hot wire _____________________________________ Fence Charger (+) ( -)
Ground wire ___________________________________
Hot wire ______________________________________ Hot wires lines hook together by insulated wire and then a insul. wire goes to (+) on the fence charger
Ground wire ___________________________________ Ground wires lines hook together by insulated wire and go to the 3rd Ground Rod
Hot wire ______________________________________
3rd Ground Rod_____ 2nd Ground Rod_____ 1st Ground Rod ____ Ground Rods hook together with underground insulated wire, which is buried- just under the ground. The insul. wire hooks to a ground rod clamp on top of each. 1st Ground Rod is buried in-ground near/below Fence charger and hooked to (-) I hope this was helpful. Do you have a Farm/Feed Store in your area like Tractor Supply Co? They can help you get everything you need.
