Whole Home Generator Installation in Dallas
Standby and portable generator hookups from licensed electricians serving Dallas, Crandall and the DFW metroplex for 15+ years.
Generator Installation Done Safely and to Code
A to Z Electric installs whole home generators and portable generator hookups for homes in Dallas and across DFW. A standby generator connects through an automatic transfer switch, so it starts on its own when the power goes out and hands the house back to the grid when it returns. A portable generator connects through an outdoor inlet and an interlock or transfer switch at the panel, never through a cord back-fed into an outlet.
Either way, we size the generator and the transfer equipment to the circuits you actually need, pull the permit and handle the inspection. You get the price before any work begins.
Backup power moved up a lot of wish lists after the rotating outages of February 2021. The goal is simple: keep the refrigerator, heat or air, lights and the essentials running without putting a lineworker at risk.

Everything the Generator Hookup Needs
The generator is only one part of the job. The wiring between it and your panel is what keeps it safe.
Load Review and Sizing
We list what you want running during an outage, check your panel and service size, and size the generator and transfer equipment to that list.
Automatic Transfer Switch
For standby generators, a transfer switch that senses the outage, starts the generator and isolates your home from the utility lines.
Portable Inlet and Interlock
For portable units, an outdoor inlet box plus an interlock or manual transfer switch at the panel, the simplest legal way to power selected circuits.
Panel Work
If the panel has no room or is near capacity, we tell you before quoting and handle the panel upgrade as part of the same job.
Permit and Inspection
We pull the electrical permit and schedule the inspection, so the installation is documented when you sell or refinance.
Surge Protection
A whole home surge protector at the panel pairs well with backup power and protects electronics when the grid comes back on.
Who a Generator Installation Is For
- Homeowners who lost power in 2021. If a multi-day outage is still fresh, a standby generator or a proper portable hookup takes the scramble out of the next one.
- Families with medical or comfort needs. Refrigerated medication, medical equipment, or relatives who cannot handle a house without heat or air.
- People who work from home. Keeping internet, a few outlets and the lights on keeps the workday going.
- Rural and edge-of-metro homes. Rural lines can take longer to bring back after an outage.
- Owners of a portable generator with no safe hookup. An inlet and interlock replaces extension cords through the window and stops dangerous back-feeding.

Generator Installation Questions
What size generator do I need for my house?
It depends on what you want running. We list the essentials, such as the refrigerator, furnace fan, some lighting and one air conditioner, check your panel and service, and size the generator and transfer equipment to that list instead of guessing.
Can I run my house on a portable generator?
Yes, with the right connection. A portable generator needs an outdoor inlet plus an interlock or transfer switch at the panel so it cannot feed power back onto the utility lines. Running a cord from the generator into an outlet is dangerous and not allowed.
What is the difference between a standby generator and a portable one?
A standby generator is installed permanently outside and uses an automatic transfer switch, so it starts by itself during an outage. A portable generator is rolled out and started by hand, then connected through an inlet and interlock to power selected circuits.
How much does a whole home generator installation cost?
The price depends on the generator size, the transfer switch, whether the panel needs work, the distance from the panel to the generator location and the permit. We quote after a site visit, and you get the price before any work begins. Our whole house generator cost guide explains each factor.
Do you pull the permit?
Yes. We pull the electrical permit and schedule the inspection for generator and transfer switch work.
