Planting and maintaining a tree has serious electrical safety implications. While a 6ft tree may not seem imposing when you plant it, it may grow to be over 40ft tall and 30ft wide and pose a threat to the electric grid.
Many service outages and interruptions are caused by tree limbs falling into power lines causing damage to wires, short circuits and other problems. This danger can be avoided by not planting tall trees under or near electric wires, and by routine tree trimming.
Do not plant trees near electrical lines; or plant low-growing trees or vegetation.
The guidelines in the diagram below aim to reduce sprouting, increase the time between pruning cycles, and help the trees planted near power lines to be healthy, safe and as attractive as possible.
