Standby Generators Installation
Generac Standby Generators by Illuminations Lighting Design
Illuminations Lighting Design installs Generac standby generators for homes throughout the Houston area. Power outages caused by severe weather, grid disruptions, or utility issues can interrupt daily life and affect essential systems in the home. A Generac standby generator provides reliable backup power that automatically restores electricity when utility power is lost.
Our company has been providing residential electrical services since 1985, and we are licensed installers for leading generator manufacturers including Generac, Cummins, and Kohler. Installing a standby generator requires proper electrical planning, load evaluation, and integration with the home’s electrical panel.
A professionally installed Generac generator helps ensure that lighting, appliances, and critical systems continue operating when the electrical grid goes down.

Why Choose Generac Generators
Generac is one of the most widely recognized manufacturers of residential standby generators. Their systems are designed specifically for home backup power and are widely used across the United States.
Generac standby generators are designed to provide:
- dependable backup power during outages
- automatic startup when power is lost
- stable electrical output for home electronics
- reliable operation during extended outages
- generator systems designed specifically for residential use
These generators allow homeowners to maintain power during storms and other events that interrupt utility service.

Automatic Backup Power for Homes
Generac standby generators are designed to operate automatically when connected to an automatic transfer switch. The transfer switch constantly monitors incoming utility power.
When an outage occurs, the transfer switch signals the generator to start and routes generator power to the electrical panel.
Once utility power returns, the system automatically switches back and the generator shuts down.
This automatic process ensures the home continues to receive power without manual intervention.
Systems That Can Be Powered During an Outage
A Generac standby generator can supply electricity to many important systems throughout the home. The number of systems powered depends on the generator size and the electrical configuration.
Backup generator systems may power:
- interior and exterior lighting
- refrigerators and kitchen appliances
- heating and cooling systems
- security systems and alarms
- garage door openers
- home office equipment and internet systems
Some generator installations power the entire home, while others focus on selected circuits.


Generator Installation Planning
Installing a standby generator requires evaluating the electrical demand of the home and determining the correct generator size.
Our electricians perform load calculations to determine the generator capacity needed to support the desired electrical circuits.
Installation planning typically includes:
- evaluating the home’s electrical load
- selecting the appropriate Generac generator model
- determining generator placement outside the home
- planning fuel supply connections
- installing an automatic transfer switch
These steps help ensure the generator system operates reliably.
Fuel Supply for Standby Generators
Most residential Generac generators operate using natural gas or propane as a fuel source. These fuels allow generators to operate for extended periods without requiring refueling.
During installation, the generator is connected to the home’s fuel supply to ensure reliable operation when outages occur.
This connection allows the generator to activate automatically whenever power is interrupted.

Generator Maintenance and Service
Standby generators require periodic maintenance to ensure reliable operation. Routine maintenance helps keep the engine and electrical components ready for emergencies.
Maintenance services may include:
- inspecting engine and fuel systems
- checking electrical connections
- testing automatic startup operation
- performing system diagnostics
Regular maintenance helps ensure the generator is prepared to provide backup power when needed.
Professional Generator Installation
Generator systems must be installed correctly to ensure safe electrical integration and reliable operation. Our electricians install generator systems according to manufacturer specifications and electrical code requirements.
Typical installations include:
- installing the generator unit outside the home
- connecting the generator to the electrical panel
- installing the automatic transfer switch
- verifying proper grounding and wiring
- testing the generator system under load
These steps ensure the system is ready to operate when power outages occur.
Licensed Generator Installation
Illuminations Lighting Design is licensed to install generator systems from major manufacturers including Generac, Cummins, and Kohler.
