An underground electrical service to a house is a type of electrical installation where the electrical service drop is buried underground, rather than being suspended from a utility pole. This installation method is becoming increasingly popular in areas with high winds, extreme weather conditions, or where utility poles are not aesthetically pleasing. In this article, we will explore the benefits, installation process, and costs associated with underground electrical service to a house.
Benefits of Underground Electrical Service
There are several benefits to having an underground electrical service to a house. Some of the most notable advantages include:
- Improved Safety: Underground electrical service reduces the risk of electrical shock or electrocution, as the electrical lines are not exposed to the elements or vulnerable to physical damage.
- Enhanced Aesthetics: Underground electrical service eliminates the visual impact of utility poles, making the property more attractive and maintaining its curb appeal.
- Reduced Maintenance: Underground electrical service requires less maintenance, as there are fewer exposed components that can be damaged by weather or physical contact.
- Increased Property Value: Underground electrical service can increase the value of a property, making it more desirable to potential buyers.
- Better Energy Efficiency: Underground electrical service can improve energy efficiency by reducing energy loss due to heat gain or heat loss in the electrical lines.
Installation Process
The installation process for underground electrical service to a house typically involves the following steps:
The first step is to determine the location of the electrical service drop and the path it will take to the house. This will require consulting with the local utility company and conducting a site survey to identify any potential obstacles or hazards.
Next, the electrical contractor will need to dig a trench for the underground electrical service, using a trenching machine or hand excavation methods. The trench will need to be deep enough to accommodate the electrical lines and any necessary conduit or cable.
Once the trench is dug, the electrical contractor will install the underground electrical service, which typically includes a combination of PVC or HDPE pipes, conduits, and electrical cables. The service will need to be sized to accommodate the electrical needs of the house and any outbuildings or secondary electrical services.
Finally, the electrical contractor will connect the underground electrical service to the electrical panel in the house and test the system to ensure it is functioning properly.
Costs Associated with Underground Electrical Service
The costs associated with underground electrical service to a house can vary widely depending on several factors, including:
Location: The cost of underground electrical service can vary depending on the location of the property, with urban areas tend to be more expensive than rural areas.
Trenching and excavation: The cost of digging the trench for the underground electrical service can range from $2 to $10 per linear foot, depending on the difficulty of the excavation and the location of the property.
Materials and labor: The cost of materials and labor for the underground electrical service installation can range from $1,500 to $5,000 or more, depending on the complexity of the installation and the type of electrical system being installed.
Permitting and inspections: The cost of permitting and inspections for the underground electrical service installation can range from $100 to $500 or more, depending on the local regulations and requirements.
Table 1: Estimated Costs for Underground Electrical Service
| Location | Trenching and Excavation | Materials and Labor | Permitting and Inspections | Total Cost |
|---|---|---|---|---|
| Urban Area | $3-$6/ft | $2,000-$4,000 | $200-$500 | $5,200-$10,500 |
| Rural Area | $2-$4/ft | $1,500-$3,000 | $100-$300 | $3,600-$7,300 |
Conclusion
Underground electrical service to a house offers several benefits, including improved safety, enhanced aesthetics, reduced maintenance, increased property value, and better energy efficiency. The installation process involves determining the location of the electrical service drop, digging a trench for the underground electrical service, and installing the electrical lines and necessary conduit or cable. The costs associated with underground electrical service can vary widely depending on several factors, including location, trenching and excavation, materials and labor, and permitting and inspections.
