Generator Installation in Waxahachie, TX

An automatic transfer switch (ATS) is the device that connects your generator to your home's electrical system. When utility power from Oncor drops, the ATS detects the loss, signals the generator to start, disconnects your home from the grid, and routes generator power to your panel. The full sequence takes 10 to 30 seconds, so you don't lose your HVAC cycle mid-run. NEC Article 702 requires the transfer switch to prevent simultaneous connection to utility and generator power, which protects both your home and Oncor lineworkers restoring grid power. A manual transfer switch requires you to physically switch over during an outage, typically outside in a storm. An ATS handles it automatically regardless of when the outage happens. Every whole-home generator install we perform includes an automatic transfer switch sized to your panel amperage.

Possibly. If your home still runs on a 100-amp electrical panel, upgrading to a 200-amp panel is strongly recommended before installing a whole-home generator. A 100-amp service lacks the capacity to handle modern household loads plus a generator transfer switch. Nearly 40% of Waxahachie's housing stock was built before 1980, according to U.S. Census housing data, and many of those homes still have original panels. We assess your current panel, service entrance, and load before specifying the installation. If an upgrade is needed, we include that scope in your written quote before any work starts. The panel upgrade requires its own permit and city inspection, in addition to the generator electrical permit. Homes in historic sections of Waxahachie near the downtown square may also have service entrance conditions that require additional assessment.

Most Waxahachie homes with natural gas service choose natural gas for their standby generator. Natural gas connects directly to your existing gas line and runs indefinitely during an outage without refueling. For homes in rural areas of Ellis County without natural gas, propane is the right choice. A 500-gallon propane tank provides roughly 5 to 7 days of continuous operation at 50% load for a 22 kW unit. Many rural properties in Maypearl and unincorporated Ellis County already have propane tanks for cooking or heating. Adding generator capacity to an existing tank often simplifies the installation. The gas line connection for either fuel type requires a permit and is performed by a licensed gas contractor. We coordinate that portion of the work as part of the full installation project.

We don't service generators or perform maintenance on generator units after installation. For generator repairs and scheduled maintenance, contact the manufacturer or its authorized service provider.

An HOA in Waxahachie can regulate generator placement under Texas Property Code Section 202.019, but those restrictions are limited. A dedicatory instrument provision is unenforceable if it increases the cost of installing the standby generator by more than 10% or increases the cost of installing and connecting electrical and fuel lines by more than 20%. An HOA also cannot withhold approval if the proposed installation meets the requirements they're allowed to regulate. In plain terms, your HOA can require the unit to be placed in a specific location or screened from street view, but it cannot effectively block you from installing a generator by making compliance cost-prohibitive. If you're in a planned community in Waxahachie or Midlothian, review your HOA's dedicatory instrument before installation begins. We can work around placement requirements as part of the site assessment.

Mr. Electric of Waxahachie does not perform scheduled generator maintenance or repair services. Those fall under the manufacturer's warranty and authorized service network. Generac, Kohler, and other major brands have dealer service networks that handle oil changes, spark plug replacement, load bank testing, and warranty repairs. We strongly recommend scheduling annual maintenance through your generator's manufacturer service network. The generator's automatic self-test function runs the unit weekly under light load, but that does not substitute for professional maintenance. We handle any electrical issues on the home side of the transfer switch, including panel work, circuit issues, or load changes after installation.

Call us or schedule your appointment online to get started. We'll gather basic information about your home, including square footage, HVAC system size, and current panel amperage. Then we schedule an on-site assessment to perform a load calculation, identify the best placement for the generator and transfer switch, and confirm gas line routing. You receive a flat-rate written quote covering the electrical scope of the project. If additional work, like a panel upgrade, is needed, that appears as a separate line in the quote.
