Fire Control received calls to an incident in Ermington electrical cable which had become detached from its pole and had set fire to two nearby trees alight yesterday.
Two fire engines from Crownhill, Plymouth and Plympton attended.
Nearby occupants reported that their electricity supply was also off.
Fire crews confirmed a live electrical cable detached from a wooden pole and fallen to the ground. Fire crews set up a cordon to keep the scene safe and requested the attendance of Western Power.

Fire crews left the incident in the hands of Western Power.
