What size generator do I need for my house?

Generator sizing depends on what you want to run during an outage, how your home is heated, and whether you need high-demand loads like a well pump, electric range, or central air conditioning. In most Fenton homes, the first step is identifying “essential loads” such as refrigerators, sump pumps, lighting circuits, internet equipment, a furnace blower, and selected receptacle circuits. Potts Electric can perform a load calculation and create a plan that balances comfort and budget without overspending on capacity you’ll rarely use.

As a general guideline, many essential-load standby systems fall in the 10–18 kW range, while whole house generator systems that cover most circuits commonly land around 20–26 kW or more depending on the home and appliances. Starting loads matter, too—motors and compressors draw a surge when they start, and that surge can dictate a larger generator or require load-shedding controls. If you want a precise answer for your address in Fenton, MO 63026, the next step is a site visit for panel evaluation, gas availability, and a room-by-room power plan.

Whole house generator vs portable generator: which is better?

A whole house standby generator is permanently installed outdoors, connected to your electrical system through an automatic transfer switch, and typically fueled by natural gas or propane. It turns on automatically during an outage, restores power in seconds, and can power either your entire panel or a prioritized set of circuits. For many homeowners, the biggest benefits are convenience, reliability, and the ability to protect critical systems like sump pumps and medical equipment even when you’re not home.

A portable generator is usually a lower upfront cost option and can work well for short outages, job sites, or powering a limited number of appliances. However, portables require manual setup, safe cord management, proper ventilation, and a code-compliant inlet connection to avoid dangerous backfeeding. If you want the portability route done correctly, Potts Electric can install a generator inlet, interlock kit (where allowed and appropriate), and dedicated circuits so you can connect safely and confidently.

If you’re deciding between the two, the next step is to define your outage goals: do you want “minimal survival power,” or seamless whole-home comfort? Contact Potts Electric for a recommendation based on your home’s electrical panel, outage risk, and budget, or explore related options like electrical panel upgrades when your system needs more capacity.

Whole house generator installation cost, run time, and central A/C capability

Homeowners often ask, “How much does a whole house generator installation cost?” Pricing varies by generator size, fuel source, site conditions, electrical scope, and whether trenching, panel upgrades, or gas line work is needed. In the St. Louis County area, a typical professionally installed standby generator system frequently falls into a wide range depending on complexity, with the generator unit, transfer switch, permits, labor, and commissioning all contributing to the final investment. The most accurate way to price your project is an on-site assessment that confirms placement, electrical routing, and the circuits you want backed up.

How long can a standby generator run continuously? Standby units are designed for extended operation, and many can run for days as long as fuel supply is uninterrupted and the unit is maintained and operating within its rated load. Natural gas standby generators can often run continuously because fuel is supplied via the utility line, while propane and diesel run time depends on tank size and load. Even with long run capability, we recommend periodic checks during extended outages and following manufacturer guidelines for oil level, airflow, and service intervals.

Can a generator power central air conditioning? Yes—many properly sized standby generators can power central A/C, but it depends on the A/C tonnage, compressor starting surge, and what else is running simultaneously. In some cases, adding a soft start kit to the A/C or using load management modules allows you to run cooling without needing an oversized generator. The next step is a load analysis that includes your air handler, condenser, and any other large loads so you can get cooling without nuisance shutdowns or poor performance.

Automatic transfer switches (ATS): what they are and whether you need one

An automatic transfer switch is the device that safely switches your home from utility power to generator power during an outage, then returns the home to utility power when service is restored. It prevents backfeeding—an extremely dangerous condition that can injure line workers and damage your home’s electrical system. For standby generators, an ATS is standard because it enables the automatic start/stop sequence, load transfer, and protective interlocking required for a safe, code-compliant installation.

Do you need one? If you’re installing a whole house standby generator, the answer is almost always yes. If you’re using a portable generator, you may use a manual transfer switch, an interlock system, or a dedicated critical-load panel depending on your goals and local code requirements. Potts Electric can walk you through the best approach for your Fenton home and can coordinate related upgrades such as whole-home surge protection to protect electronics when power switches and returns.

If you’re not sure what you have today, the next step is a quick panel and service inspection to confirm your current setup and recommend the safest upgrade path.

Fuel options and maintenance schedules for standby generators

Standby generator fuel options typically include natural gas, propane, and diesel, and the “best” choice depends on availability, storage preferences, and runtime expectations. Natural gas is popular in Fenton because it can provide long-term operation without refueling and is generally convenient for residential standby installations. Propane is a strong option when natural gas isn’t available; it burns cleanly and stores well, though runtime depends on tank size and you’ll need a delivery plan during extended outages.

Diesel is often associated with higher torque and strong performance under heavy loads, but it requires on-site fuel storage and careful maintenance to keep fuel stable over time. For many residential customers, natural gas or propane offers the best balance of convenience and clean operation, while diesel may fit specific needs or properties. Potts Electric will help you select the right fuel configuration and ensure the installation meets clearance, ventilation, and code requirements.

How often does a standby generator need maintenance? Most manufacturers recommend routine service at least annually or after a certain number of run hours, with oil and filter changes, battery testing, and inspection of wiring, exhaust, and transfer switch operation. Even if your generator “exercises” weekly, it still needs professional maintenance to confirm it will perform under real load during an outage. The next step is setting up a scheduled maintenance plan so your generator is ready when storms or utility issues hit Fenton, MO 63026.

Installation requirements, permits, and troubleshooting when your generator won’t start

Generator installation requirements include proper placement and clearances, correct conductor sizing, grounding and bonding, compliant transfer equipment, and safe routing of electrical and fuel connections. In most cases, installing a standby generator also involves coordinating with the local authority having jurisdiction for inspections and completing the electrical permit process. Potts Electric handles these details, ensuring your system is installed to applicable code standards and that the final setup is tested and commissioned correctly before we leave.

If you’re calling because your generator won’t start, there are several common causes we can help you check and resolve. Frequent culprits include a weak or dead battery, fuel supply issues (closed gas valve, empty propane tank, stale fuel on portables), clogged air filters, low oil level, tripped breakers, or fault codes that indicate a sensor or control issue. Sometimes the generator starts but won’t carry load due to transfer switch problems, wiring issues, or overload conditions that require a load plan adjustment. Potts Electric can troubleshoot the generator, the transfer switch, and the connected circuits to restore dependable operation and prevent repeat failures.

If you’re experiencing starting issues or want to confirm your current setup is safe, the next step is to schedule a diagnostic visit and have our electricians verify fuel, controls, transfer switching, and load performance.
