Generator Installation- A Complete Guide

Vance Electric • June 23, 2022

In 2021, North Carolina experienced 674 power outages affecting over 4 million residents. That's why many NC residents are choosing to install a generator at home.

A generator ensures your home maintains uninterrupted power during weather emergencies and power outages that are becoming increasingly common in this part of the country.

Do you want to be one of the homes on your block whose lights remain on during the next emergency? Rest assured your life can continue as normal when you install a home generator.

Keep reading to find out everything you need to know about generator installation from a Generac dealer in Northeastern North Carolina and Southeastern Virginia.

What Is a Home Generator?

The purpose of a home generator is to create an alternate power source. This is essential during a power outage.

Generators typically run on gasoline. They convert mechanical energy into electric energy. This is done through internal combustion and by manipulating magnetic fields.

Generators are especially helpful during long periods without power. They prevent food from going to waste and mitigate any interruptions in heating or cooling your home.

Planning and Preparing to Install Your New Generator

When it comes to generator installation, planning ahead is key. It is important to partner with a trusted generator expert for your generator installation.

They will use their expertise to help you find the right generator and pad location for your home. Here are some of the things you need to consider when preparing to install a generator.

Choosing the Right Generator Size

The size of your generator depends on the amount of power you require. How many electrical appliances do you need to keep running for your home to function properly?

Maybe your plan is only to power the essentials, like lights, refrigerator, freezer, and internet. In that case, you should be able to get by with a 7.5kW generator. Portable or standby generators should both work well.

A 10kW offers a little bit of an extra boost. With this size generator, you can power your essential appliances and a small well pump. It may also power a larger electrical appliance if you use it conservatively.

For a household with four people, a 14kW generator should be capable of powering the home like business as usual. This type of generator is a standby generator that can power an entire electrical panel.

For larger homes, a 20kW generator is essential. This size of a standby generator is capable of powering your home's entire panel.

For reference, the sizes recommended here are intended for homes that rely mostly on gas appliances. If your home uses mostly electric appliances (water heaters, ovens, well pumps), you will require a larger generator.

Selecting the Best Location

Every generator installation requires certain clearances. This varies depending on the type of generator and where you live. A Generac dealer in Northeastern North Carolina and Southeastern Virginia, will have the required local expertise to guide you in this process.

Most generators need to sit at least 18 inches away from any structure. This includes your home, garage, and any other detached buildings on your property.

Generators also need to be at least five feet away from windows, doors, and any other openings to your home.

An ideal location for a generator is next to your air conditioning system. These are typically located on the side of the home that gets the least traffic, which is generally the safest location.

Getting the Right Permits

It is necessary to get a permit when planning and preparing to install a generator at your home. You can find out what permits you need and how to apply for them through your county permit office.

Pouring the Generator Pad

A generator requires a flat and level surface for installation. Most generators sit on a gravel or concrete pad. If you place a generator on bare ground, eventually, it will begin to tilt from the vibrating weight of the unit.

This can damage the generator and your property. It also makes the generator unsafe to run.

Your generator installation expert will also install a level generator pad to avoid any such issues.

How To Install a Generator

Generator installation typically takes a matter of a few days. This is best handled by an experienced electrician specializing in generator installation.

Securing the Generator to the Pad

The first step of the generator installation is to secure the unit to your concrete or gravel generator pad. You must get a professional to do this because generators vibrate and move a lot.

Connecting the Fuel Line

To install a generator requires installing underground conduits for both the fuel line and the electrical line. That means the person you hire to install your generator needs to dig and then do some landscaping to cover that area.

Installing the Transfer Switch

The transfer switch is what senses when the regular power has gone out in your home. This switch transfers your power source to the generator automatically, so you don't lose power for more than a moment.

Connecting the Electrical System

After the electrician installs the transfer switch, there is only one step left in the generator installation process. Once the electrician connects the generator to your home electrical system, you are ready to go.

How To Avoid Generator Problems After Installation

Once your generator gets installed, there are a few things you need to do to keep your generator running smoothly.

Your generator supplier should offer a warranty for your generator purchase. However, there are other things you can do to avoid generator issues during the next power outage or emergency.

Get a Generator Inspection

After installation, it is beneficial (and likely necessary) to get a generator inspection. This will be done by a local inspector from your jurisdiction.

Perform Annual Maintenance

Just like any machine, generators require regular maintenance. The best way to make sure this gets done is to get an annual contract with a service company. That way, you know you'll have regular maintenance checks.

According to the National Centers for Environmental Information, each of the twenty-seven weather disasters that occurred in 2024 cost more than one billion dollars . Part of the reason these storms are so expensive is that they can knock out power infrastructure, causing outages. That is why it is so essential to have home backup power . But where do you get this type of reliable power backup power? And what safety considerations should you take into account? This emergency power options guide will answer these questions to prepare you for the next storm. The Risks of Power Outages During Storms Power outages during storms create various challenges, many of which can severely impact families. Losing electricity disrupts everyday routines, affecting lighting, heating or cooling systems, and access to communication. This makes staying connected with emergency services, loved ones, and weather updates difficult, leaving families vulnerable during a crisis. Beyond daily inconveniences, power outages also pose significant health and safety risks. Without refrigeration, perishable food can spoil, increasing the risk of foodborne illness. A prolonged outage can become a medical emergency for individuals who rely on medical devices such as oxygen concentrators or CPAP machines. Additionally, extreme temperatures can make homes uninhabitable, leading to dangerous conditions, particularly for children, older people, and those with health concerns. The financial burden of power outages can also be substantial. A sudden power surge can damage expensive electronics and appliances, leading to costly repairs or replacements. Types of Backup Power Solutions Several types of home backup power solutions are available, each with unique benefits and considerations. Portable generators offer a cost-effective and flexible option capable of powering select appliances. However, they require manual setup, fuel storage, and proper ventilation to prevent carbon monoxide poisoning. These generators are ideal for short-term power outages but require careful handling to ensure safety and efficiency. Learn more about in-stock generators . Standby residential power generators provide automatic power restoration during an outage for a more seamless solution. These units are permanently installed and typically run on natural gas or propane, eliminating the need for refueling. Standby generators can power an entire home and offer a reliable, long-term solution. However, they require professional installation and regular maintenance to maintain optimal working conditions. Read about professional generator installations and their benefits. Battery backup power systems provide another alternative, storing electricity during outages. While they are well-suited for short-term power needs, their effectiveness depends on battery capacity. For families looking for a sustainable and long-term solution, combining solar power with battery storage ensures electricity is available even during extended outages. Just make sure you are choosing the right generator . Choosing the Right Backup Power for Your Family Selecting the best backup power solution depends on various factors, including household power needs, budget, fuel availability, and ease of maintenance. Assessing power requirements is the first step in determining which appliances and systems must be operational during an outage. Understanding essential devices' wattage and energy consumption helps identify the appropriate generator size. Find the size generator you need to ensure your home is adequately powered. Budget is another critical consideration. Portable generators have a lower upfront cost but may require frequent refueling and maintenance. Standby generators involve a higher initial investment but provide automatic power restoration and long-term reliability. Battery backup systems and solar power solutions also have varying price points, with potential long-term savings on energy costs. Explore the complete guide to generator installation to make an informed decision. Fuel availability plays a crucial role in backup power planning. Portable generators often run on gasoline, which can be scarce during severe weather events. Standby natural gas or propane generators provide a more consistent fuel source. Battery-powered solutions eliminate the need for fuel but depend on stored energy capacity. Learn about the benefits of a Generac standby generator for a dependable energy source. Some generators require frequent servicing, while others offer automated operation with minimal intervention. Proper installation and routine maintenance ensure the system functions correctly when needed. Get essential maintenance tips to extend the lifespan of your generator. Safety Considerations When Using Backup Power Backup power solutions provide security during power outages, but proper usage is essential to prevent safety hazards. Portable generators can produce carbon monoxide poisoning , which is a significant risk. Therefore, it is crucial to operate them outdoors, away from windows and doors. Homeowners should install carbon monoxide detectors to monitor indoor air quality and prevent exposure to this deadly gas. Electrical hazards are another concern when using backup power. Qualified professionals should always install generators to avoid the risk of electrical shocks, short circuits, or fire hazards. Proper grounding and adherence to local electrical codes ensure safe operation. Find out more about preparing your home for generator installation. Safe fuel storage and handling are also vital when using generators. Gasoline and propane should be stored in approved containers and kept away from living spaces. Spills should be cleaned immediately to reduce fire risks. Routine maintenance, including oil changes and component inspections, helps keep generators in peak condition and ready for emergency use. Learn more about generator repair and warranty services . Additional Storm Preparedness Tips Beyond the benefits of professional generator installation for backup power, families should take additional steps to prepare for storms. Create an emergency kit stocked with the following: Non-perishable food Water First-aid supplies Flashlights Extra batteries A battery-powered radio or alternative communication method helps families stay informed about storm developments and emergency updates. Developing a family emergency plan is also critical. Establishing communication protocols, designating meeting points, and outlining evacuation routes help ensure everyone knows their role during an emergency. Staying informed through weather forecasts and local emergency alerts provides valuable time to implement preparedness measures. Need Home Backup Power?
