"We hired Bi-State Electric to run a 20 amp circuit from our house to our new garden shed. This required Scott to hand dig a trench about 25 feet long between the house and shed. He installed a small porch light on the shed and a ceiling fan/light inside with switches to operate both. He also installed a total of 5 outlets at various locations inside the shed. As an added service, Scott installed a Whole House Surge Protector to our electrical panel and provided a safety inspection of the panel at no additional cost above his quoted price. Once the work was completed, the County Inspector came out and gave his stamp of approval."

Generator Install FAQs, answered by experts

Your home is an excellent candidate for generator installation if you live on a rural route or rely on a private well pump. Homes in Farmington with older electrical panels require an upgrade to ensure compatibility with a transfer switch. You must also have adequate space for proper setback requirements and a reliable fuel source, whether that is city natural gas or a correctly sized propane tank for your MO property.

Helpful?

Maximize safety during generator installation by building a code-compliant fence around the unit to protect children and pets from moving parts. Direct the exhaust away from windows, doors, and HVAC intakes to maintain safe air quality. Missouri law requires properly placed carbon monoxide detectors inside your home. Finally, choose a placement that complies with Farmington noise ordinances to ensure a peaceful environment for your family and neighbors.

Helpful?

Proper weatherproofing against humid summers and wet winters is essential for the longevity of your generator installation. You must place the unit in an accessible, level location to guarantee easy routine maintenance on sloped MO properties. Hiring licensed contractors ensures your system features a code-compliant transfer switch and proper grounding. Passing the required Farmington city inspections confirms your system operates safely and withstands severe weather for years to come.

Helpful?

You must prioritize generator installation immediately if your household relies on electrically powered medical equipment or a private well pump. For other homes, schedule the work before the spring severe weather season or the winter ice storms hit Farmington. Waiting until after a major MO storm guarantees long delays due to high demand for local professionals. Plan ahead and secure your permits during calm seasons to avoid extended wait times.

Helpful?

The physical work for generator installation takes one to two days to complete. However, you must account for permit processing and utility coordination, which add several business days to your timeline. Local professionals in Farmington experience high demand after severe storms, extending wait times by weeks. Schedule your project during calmer weather in late fall or early winter to ensure a faster process for your MO home.
