The "big Green Boxes" are transformers that change the voltage from 14,000volts to 120volts for our homes. Inside the box is something called elbows that allows a service person isolate the 14,000volt cable in the event of a "fault". An 8 foot "hot stick" and a whole lot of dexterity is needed to pull these elbows. If plants are in the way they will be cut or pulled out for the safety of the service person. 14,000volts will create a big ball of fire and "cook" a person in seconds.
