Electric lines, or service drops, are the bundles of electrical cables that run from the electric utility company's power pole to a house. The cables are either suspended above ground or installed underground. The service drop connects to an assembly called the service head, which consists of a rigid steel conduit that runs up through the roof or along an exterior wall. The bottom end of the service mast connects to the home's meter base. From the meter, an additional set of service cables runs through the service head and connects to the service drop cables near the mast, representing the dividing line between the utility company's property and the homeowner's property.

What You'll Learn
Electric lines run from the utility pole to the house
Electric lines from the utility pole to the house are known as the service drop. This is a bundle of electrical cables, or three individual wires in older installations, that run from the electric utility company's power pole to the connection at your house. The cables descend from a higher spot to a lower spot, and they must be at least 12 feet above the ground. The minimum height requirements for service drop cables are determined by local building or electrical codes, but most follow the recommendations of the National Electrical Code (NEC).
The service drop is a key element that funnels all the electricity into your home. If it goes down, all the power in your home will shut off. If there is a problem with the service drop, you should contact your utility company. Fallen service drops are extremely dangerous as they carry enough electricity to power an entire house, so they should not be approached.
When the service drop reaches the house, it connects to an assembly called the service head, service mast, or masthead. This typically consists of a rigid steel conduit that runs up through the roof or along an exterior wall, topped with a shell-like fitting called a weatherhead or weather cap. The bottom end of the service mast connects to the home's meter base.
The electrical cables that run from the power pole to the house are usually three insulated cables: live, neutral, and ground. These cables are loosely twisted around a strain relief cable, which supports their weight and relieves strain on the attachment points.

The service drop connects to the service head
When the service drop reaches your house, it connects to an assembly called the service head, service mast, or masthead. The service head is usually a rigid steel conduit (like a large pipe) that runs up through the roof or along an exterior wall. It is topped with a shell-like fitting called a weatherhead or weather cap, which has an open front that faces downward to prevent rain and snow from entering the service head. The bottom end of the service mast connects to the home's meter base.
The service drop is the bundle of electrical cables, or three individual wires in older installations, that run from the electric utility company's power pole to the connection at your house. The cables descend from a higher spot to a lower spot since the power company lines are higher than your home. The service drop is the main connection between the power pole and your house, and it includes three cables or conductors: live, neutral, and ground. These cables provide 200 amp electrical service to most homes.
Before connecting to the service head, the service drop cables make a downward loop near the service point, known as the drip loop. This simple system uses gravity to prevent water from running down the cables and into the service head. Any water travelling down the outside of the cables collects in the loop and eventually drops off. The service point is the connection between the service drop cables and the cables that start at the service panel and the electric meter, running through and out of the service head.
The service point represents the dividing line between the utility company's property and the homeowner's property. While the meter may be owned by the utility company, it is typically located on the homeowner's side. Homeowners are not allowed to work on any part of the utility's service drop or the cables between the service drop and the home's electrical service panel as these cables are live at all times. If there is any problem with the service drop, the utility company should be called. However, if there is an issue with the service head or the cables between the service point and the main panel, a licensed electrician should be contacted.

The service head consists of a rigid steel conduit
Electric lines run into a house through a bundle of electrical cables, known as an electric service drop. This service drop connects to an assembly called the service head, which consists of a rigid steel conduit.
The rigid steel conduit, or service head, is a large pipe that runs up through the roof or along an exterior wall. It is topped with a shell-like fitting called a weatherhead or weather cap, which has an open front facing downward to prevent rain and snow from entering. The bottom end of the service head connects to the home's meter base.
The rigid steel conduit is typically made of steel with a thick-walled metal raceway. It can be galvanized steel with a coating of zinc on the exterior and interior, or it may have a combination of zinc and non-metallic coatings. Supplementary coatings can also be applied to provide additional corrosion protection. The conduit is threaded on both ends, with one end having a coupling and the other a color-coded thread protector.
The service head is an important component of the electrical system in a house. It serves as the connection point between the electric service drop and the home's meter base. An additional set of service cables starts at the service panel and runs up through the service head, connecting to the service drop cables. This connection, known as the service point, represents the dividing line between the utility company's property and the homeowner's property.

The service cables run from the service panel to the service head
The service head is an assembly that the service drop connects to when it reaches the house. Typically, it consists of a rigid steel conduit that runs up through the roof or along an exterior wall. The bottom end of the service mast connects to the home's meter base. The service head is also known as the service mast or masthead. It is topped with a shell-like fitting called a weatherhead or weather cap, which has an open front that faces downward to keep out rain and snow.
The service cables that run from the service panel to the service head are an additional set of cables that start at the service panel (and the electric meter) and run 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. The service point is typically located near the service head.
The service drop is the bundle of electrical cables that run from the electric utility company's power pole to the connection at the house. The service drop is higher than the house, so the cables descend to reach the connection. If a house does not have a service drop, it is supplied by similar cables running underground. All electricity to the house comes through the service drop. If the service drop goes down, all power in the house will shut off.
The service cables that run from the service panel to the service head are an important part of the electrical system in a house. They connect the service drop cables to the service panel and the electric meter. These cables are typically located near the service head and are owned by the utility company. Homeowners should not attempt any work on these cables and should call the utility company if there are any issues.

The electrical service meter and the main disconnect
The electrical service meter is the point where the electrical cables from the utility company connect to your home's electrical system. It is typically located near the main electrical panel, which houses the main disconnect, also known as the main breaker assembly. This assembly is where the electrical service feed enters your home and is distributed to the various circuits and outlets.
The main disconnect is a critical component of your home's electrical system, as it allows you to shut off all power to the house in case of an emergency or when doing electrical work. It is usually located at the top of the electrical panel and consists of two or more large breakers that can be switched off to cut power to the entire house.
In some cases, there may be a need for a disconnect switch between the electric meter and the service panel. This could be for various reasons, such as installing a whole-house generator or adding more control over individual breakers. If this disconnect switch is not an emergency disconnect, it will become the service disconnect, and specific wiring requirements must be followed.
It is important to note that the meter itself may have a disconnect switch, which is different from the main disconnect. The meter disconnect switch is usually required by utility companies to allow linemen to shut off power before pulling the meter for maintenance or other purposes. This prevents the risk of electric arcs when the meter is removed while under load. Proper labelling is crucial to distinguish the meter disconnect from the service disconnect.
