Cable Runs for Dogs have been around forever . However not property installed it can be disastrous when lightning hits close to or directly on the wire.
I was recently at a home where lightning hit a dog run and severely damaged a detached garage because there was not an insulator used to attach the wire to the garage.
You can see where Lightning went across the wire into the garage destroyed anything electronic and then discharged down thru the foundation cracking it.
Had a simple Ceramic Insulator been used to disrupt the path of the lightning the majority of the damage could have been avoided .
The lightning charge instead would have taken the least oath of resistance which was the tree. I have even seen dog runs wire taken and pout all way to the ground and attached to a ground rod but it must be dine properly to avoid step voltage.
A simple screw-in insulator is available most hardware and home centers in the electrical aisle and simple to install and attach wire to so it does not make contact with the structure
