Who is responsible for maintaining power lines?
service panel that houses your fuses or circuit breakers.
distributes electricity through your home.
As a customer, it’s also your responsibility to maintain open access to the meter and keep obstructions away from power lines that extend from the utility pole to your home..
How close to power lines can you plant trees?
Never plant a tree near a power line that could grow within 25 feet of it. Tall growing trees should be planted a minimum of 20 feet away from power lines, and 50 feet away to avoid future pruning. A mature height of less than 15 feet is recommended for trees planted near power lines.
What is the minimum safe distance from energized overhead power lines?
2 feetThe following minimum clearances must be maintained between scaffolds and exposed energized power lines: 2 feet for insulated power lines of less than 300 volts . . .
What happens when a tree limb touches a power line?
If you climb a tree near a power line and touch the power line, electricity will go through you and you can be hurt or killed. If a tree branch falls on a power line, it can cause a power outage. … If a tree branch touches a high-voltage power line, electricity from the line can make the branch so hot it catches fire.
Do power companies remove trees?
However, the law allows an electric company to trim or remove a tree, under certain circumstances, without notifying the property owner. … Neither the law nor PURA decisions appear to allow the company to bill the property owner for subsequent work if the owner initially refused to permit the trimming or removal.
Can you hang off a power line?
Hanging from a power line you should be as safe as a bird. The voltage difference is between the lines (e.g. in a 3-phase system) and between the line and ground. … As the distance between the lines will usually be smaller than that between your feet and the ground, again no current will flow, and you will be safe.
What are the three wires coming into my house?
House wiring is installed using cables. 120-volt cables will have three wires: one black, one white and one bare conductor. The black is the hot wire, the white is called the neutral and the bare wire is the ground. A 220-volt cable will have an additional hot wire, red in color.
Who is responsible for the wire from pole to house?
The wire that runs from the utility pole to your house and the meter itself are the responsibility of OG&E. The cable that runs from the side of your house as well as the box that holds the meter are owned by, and are the responsibility of, the homeowner.
Can I touch the power line going to my house?
Power lines coming from the transformer to your house are covered and okay to touch. 5. … It is safe to climb a tree located near a power line as long as the limbs aren’t touching the line.
How can I get trees cut for free?
How to Remove Trees for FreeCheck to see if your trees are part of a city, state or federal program. … Post ads, either in stores, laundromats or online bulletin boards, advertising free wood for anyone willing to cut it up and haul it away. … Call the power company to remove any unwanted trees that are near power lines. … Cut down the trees yourself.More items…
Why do birds not get electrocuted when standing on power lines?
Birds on power lines don’t get shocked because they are not in contact with the ground or other conductive element that is in contact with the ground. If the bird were to touch another wire at the same time, and that second wire was of a differing resistance, it could be electrocuted.
Why do lightning hit trees?
Weather Library > Lightning Strikes to Trees. … And for a good reason – trees protrude from the earth’s surface, making them frequent victims of direct lightning strikes. Electricity seeks the path of least resistance, and the moisture (sap and water) inside a tree is a much better conductor than air.
What wire is used for service entrance?
All service-entrance cable is rated 600V and is listed in sizes 14 AWG and larger for copper and 12 AWG and larger for aluminum or copper-clad aluminum conductors.
What are those things hanging from power lines?
They’re called visibility marker balls or marker balls. You’ll often find them near mountain passes, in the deep valley areas, near major freeway crossings and around airports. They weight about 17 pounds each. The marker balls are placed on power lines to make the conductor crossings visible to aircraft.
What is the minimum height for overhead cables?
For power lines above areas used only by pedestrians, including sidewalks, decks, and patios, the rules for minimum vertical clearance of wires above the ground are: For lines carrying 150 volts or less: a minimum vertical clearance of 10 feet. For lines above 150 volts: a minimum vertical clearance of 12 feet.
Can you cut a tree limb that is touching a power line?
Call the electric utility instead. You don’t have to touch any wires personally to headline a big story in your local paper. Just touching a branch that’s touching a wire can cause fatal injury, as the voltage on a typical overhead power line can be a hundred times greater than your indoor household current.
What is electrical clearance?
The electrical clearance is the electrical isolation between two conductive components, whereas the creepage indicates the conduction of electricity across the surface of a nonconductive component. The clearance and creepage distance are two important parameters while designing an electrical assembly.
What is the average height of a power line?
The standard height of power lines depends entirely upon the city and state they’re in and the types of power lines on the pole. Despite recommended minimum ground clearance levels starting at 12 feet, industry standards now lean toward 35 feet or higher.
Why do power lines have 3 wires?
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power.
