How many types of electric poles are there?
They can be divided into three types namely; Tangent distribution poles, guyed distribution poles, and self-supporting distribution poles.
Why are there 3 power lines?
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.
Is it safe to live next to a utility pole?
Most scientists believe that exposure to the low-level EMFs near power lines is safe, but some scientists continue research to look for possible health risks associated with these fields. If there are any risks such as cancer associated with living near power lines, then it is clear that those risks are small.

How to check if your service mast is damaged?
It could be but isn’t necessarily your service mast. Locate your mast outside by finding your meter box and following the mast up to the roof. If the mast looks dented, disconnected, or otherwise damaged at any point, then the components inside could be damaged, too. Check the connected supply drop wires while you’re at it, but don’t get too close and don’t touch them!

How does electricity run from power lines to homes?
Electricity runs from overhead power lines down to your home through a collection of wires called “service drops” because of the way the wires literally drop from the overhead power lines down to your home. These service drops enter the structure at a slanted plastic cover called a weatherhead. Inside the weatherhead, the service drops connect to the service entrance conductors at the “service point.”
Why is my meter socket loose?
Loose or disconnected meter socket: This might happen as the result of construction, weather, or debris falling hard enough to knock the service entrance conductors off of the meter.
What is the name of the wires that run from power lines down to your home?
The wires that run from power lines down to your home are known as “service drops.” These drops connect to your home at the mast. The service mast transfers distributed municipal electricity to your individual home’s system. Those wires connected to your home are how your home receives power!

What is the service head on a house?
When the service drop reaches the house, it connects to an assembly called the service head, also know as the service mast or masthead. Typically, a service head consists of a rigid steel conduit (like a big pipe) that runs up through the roof or along an exterior wall and is topped with a shell-like fitting called a weatherhead or weather cap.
How does a weatherhead work?
The bottom end of the service mast connects to the home's meter base. An additional set of service cables starts at the service panel (and the electric meter) and runs up through and out of the service head. These cables connect to the service drop cables near the outside of the mast. This connection is called the service point, and it represents the dividing line between the utility company's property and the homeowner's property (although the meter may be owned by the utility even though it is on the homeowner's side).
