Before every underground installation, there are seven things to undertake

 To replace overhead wires with underground cables, underground wire installations are created. They provide an effective way to reduce blackouts and outages caused by wind thunderstorms. In contrast to overhead lines, which tend to obstruct the sky, they are also quite attractive.
I'll concentrate on underground wire installation in homes and residential subdivisions for this article, which will only be possible after determining whether such work is feasible. For that process, engineers, developers, and electricians must be well-prepared.

Let's first take a look at some crucial points.
When should an underground wire installation be planned?
When the client wishes to give its garden or yard some extra power.
When there is no way to proceed with overhead underground wire installation during transmission line construction, which usually happens in areas with natural barriers, fragile ecosystems, or simply a rich history.
When a client wants to choose a more environmentally friendly choice for health grounds, such as when they have leukemia disease and want to limit magnetic field emissions.
How to install underground: Steps to take
1) Talk with the customer
Give the customer a clear understanding of what is happening; you are the professional, he is not, therefore engage in a meaningful conversation with him. The majority of the time, clients alter their installations to imitate or to stay current. It's important to take into account the following:
What kind of project is it—a renovation or an extension? Explain in detail what is involved in that project and where its obligation begins, depending on what he wants to know. Before beginning any subterranean installation, you should be able to explain to him how you will proceed and what he can do (dig the trenches for example).
The electrical pole and the telephone pole share the same pole, right? If a joint connection is possible, he should then call the phone provider to request permission to carry out such actions.
What time does he want to begin? This will assist you in beginning to plan your job. He ought to be aware of how long the task will take to complete.
2) Make a site visit to choose the trench and route for your underground installation.
This is of utmost importance because it aids in the evaluation of the project's viability as well as the work itself. It will be thoroughly examined how the loads and terrain will affect the ability to build and maintain those subsurface facilities.

Before digging any trench, the client is typically required to obtain permission. Ordinarily, the underground meter will be installed next to the overhead electrical supply, but if the client requests a different position, confirm this with him and request a copy of the new suggested location.
3) Decide how to install the cables.
The methods for underground wire installation vary depending on the project, the budget, and the application. The most typical installation style is direct buried cable.
Why? Perhaps because it is the most affordable and offers homeowners a decent financial option. Surface troughs are typically utilized in areas without vehicular traffic, whereas ducted techniques are more expensive but need less time to build. The decision is based on the project's level.
4) Determine the installation's material requirements.
We will have PVC conduits, PVC coupler, etc. for direct underground wire installation specifically, trenching shovels, marker flags, warning subterranean tapes, meter tape to measure the distances, hammer, etc. depending on the project and the type of installation.
This evaluation is crucial to the project's development since it prevents any delays that could result from inadequate planning.
5) Complete the client's contract.
A contract is drafted and then signed by the customer with the cost and estimation of the material and equipment involved after drawing the suggested installation route agreed upon by both the client and the utility company's representative.
6) Electrical installation procedure from the meter socket to the control box
For underground wire installation, the client engages a licensed electrician. The client should be informed of the specifics of the electrician's work. After a specific amount of time, there are no additional maintenance tasks beyond those listed in the agreement.
Many clients enjoy having their other electrical issues presented during such treatments. No, why not if the issue is a straightforward light fix? Inform the client where the project should begin and what you want to perform, such as installing a metal socket, connecting it to its control panel, and waiting for an inspection. I'm done now.

7) Schedule an inspection.
Before beginning any subterranean project, this is an essential step. For those works, many authorities required a permit. An inspection gives you the chance to assess some crucial aspects of the project, such as trenches and conduits (trench depth, sand bed, etc.), structures (backfills, property pins, access, etc.), and streetlights (base alignment or base grade), all of which appear at various stages of the process, including trenching, grounding of structures, and ductwork. The final work schedule is then established.
Although there are many alternatives and benefits to using this method, one drawback is the high installation costs, which can be up to 14 times higher than those of overhead installations.
Conclusion
Electricians should always check the regulations board and policies of each town to see if they approve any underground installations there and to find out more about the underground wire installation requirements there, such as the minimum size of buried conduits, the color of ducts, the depth allowed for conduit system installations, etc.
When working on these projects, always take your time and be cool because anything can suddenly become dangerous.
