Some say that an electric fence can start a fire with the vegetation around it.
However, the likelihood of this happening is actually quite low.
In order for an electric fence to start a fire, all of these conditions would need to be met:
The fence is improperly maintained (broken or damaged wires and insulators) An abundance of dry vegetation around the fence A damaged wire shorts to a metal object such as a metal fence post
With this in mind, an electric fence is unlikely to start a fire.
