FAQs
Why should I install a standby generator for my Tellico Plains home or business?
Tellico Plains experiences severe thunderstorms, winter ice, and occasional tornado-related outages that can leave customers without power for hours or days. A permanently installed standby generator automatically restores electricity within seconds, protecting refrigerated food, medical equipment, sump pumps, internet routers, and sensitive electronics. For businesses, uninterrupted power keeps POS systems, security cameras, and critical data servers running, preventing costly downtime and product loss.
What size generator do I need and how is the capacity determined?
Proper sizing depends on the starting and running wattage of the appliances, HVAC equipment, well pumps, and other loads you want to power. Our technicians perform a free on-site load analysis using amp-meter readings and manufacturer specifications. We then apply a 20–25 % buffer for motor start-up surges and future circuit additions. Residential systems in Tellico Plains typically range from 14 kW to 24 kW, while small businesses often choose 30 kW to 60 kW three-phase units.
How often do generators need maintenance and what services do you provide?
Manufacturers recommend service every 6–12 months or after 200 hours of run time, whichever comes first. Our Generator Care Plan includes semi-annual oil and filter changes, spark-plug replacement, valve adjustments, battery inspection, firmware updates, complete load-bank testing, and remote monitoring. Regular maintenance preserves the warranty, maximizes fuel efficiency, and ensures your unit starts instantly when Tellico Plains Utility Board reports an outage.
Will a generator work with my existing electrical panel and fuel supply?
Yes. During consultation we verify panel capacity, grounding, and bonding to meet the latest NEC and Monroe County codes. We install an automatic transfer switch (ATS) matched to your panel’s amperage—usually 200 A for homes and 400 A or higher for commercial sites. Generators can run on propane or natural gas. If you currently have a propane tank, we size the regulator accordingly; if you’re on natural gas, we check line pressure and meter size to confirm adequate BTU flow.
How long does installation take and will I need permits in Tellico Plains?
A standard residential installation takes 1–2 days: day one for concrete pad placement and fuel line trenching, day two for electrical tie-in and commissioning. Commercial projects can take 3–5 days. We pull all required electrical, mechanical, and fuel gas permits from Monroe County Building & Codes and schedule the final inspection. Homeowners do not typically need to be present for inspections, and we coordinate with the Tellico Plains Utility Board for any planned service disconnects.
What happens during a power outage – will the generator turn on automatically?
When utility voltage drops below threshold for more than 3–5 seconds, the ATS signals the generator to start. Once the engine reaches rated speed (about 10 seconds), the ATS transfers your building’s circuits from utility to generator power. When utility service is restored and stable for a preset duration—usually 60 seconds—the ATS switches back to grid power and the generator enters a cool-down cycle before shutting off. Throughout the process, power to critical loads is seamless, so lights, HVAC, and electronics stay on without interruption.
