i remember that one from a long time ago. i wonder why he used the adapter. it showed him plugging it into a 3 prong outlet. i think he may have touched the fence the same time the frayed wires did.
one way this could have been avoided was hired professionals to the job. i live in a town with around 25000 people. it seems like every year there are 25- 30 people injured doing somthing that they dont either have proper tools or know how.
