Generator installation and service in Missoula, MT for homes and businesses facing frequent outages or critical power needs
Redcliffe Electric installs and maintains standby generators for homeowners and business owners who need uninterrupted power when utility service fails. You rely on electricity for heating, cooling, refrigeration, medical equipment, security systems, and communication devices, and a properly sized generator keeps those systems running during storms, grid failures, or scheduled outages. The work begins with a load calculation to determine which circuits need backup and what fuel source makes sense for your property.
A standby generator connects directly to your electrical panel through an automatic transfer switch, which detects a power loss and starts the generator within seconds. The transfer switch isolates your home or building from the utility line to prevent backfeeding, then routes generator power to designated circuits. Natural gas and propane are the most common fuel sources because they provide continuous operation without refueling, though diesel systems are used in some commercial settings. The generator runs until utility power returns, then shuts down and switches the load back to the grid.
If you are evaluating generator options or need a site assessment to determine system capacity and placement, reach out to discuss load requirements and fuel availability.
Sizing and Installing a Generator That Matches Your Load
You need a generator that can handle the startup surge of motors and compressors, not just the running wattage of lights and electronics. Air conditioners, well pumps, and refrigerators draw several times their rated power when they first turn on, so the generator must be sized to accommodate those inrush currents without overloading. Redcliffe Electric calculates total connected load and applies diversity factors to recommend a unit that runs efficiently without unnecessary oversizing.
After installation, your transfer switch operates automatically during an outage, and you will hear the generator start within ten to fifteen seconds of losing utility power. Lights stay on, the furnace continues to run, and refrigeration remains active. The system runs a self-test weekly to confirm the battery is charged, the oil level is adequate, and the engine starts cleanly. You receive audible or visual alerts if the test fails or if maintenance is due.
Generator pads must be level, vibration-isolated, and located according to setback requirements. Gas line sizing must support the generator's maximum fuel demand, and exhaust outlets must be positioned away from windows, doors, and air intakes. Electrical connections are made at the transfer switch, which is installed near the main panel. Permits and inspections are required for both the electrical and fuel supply work.
What to Know Before Installing a Generator
The following questions address common concerns about generator selection, installation, and maintenance.
- What size generator do I need for my home? You need a unit sized to handle the combined startup load of your largest appliances, typically ranging from eight to twenty-two kilowatts for most residential applications depending on square footage and whether you include central air conditioning.
- How long can a generator run continuously? Natural gas and propane generators can run indefinitely as long as fuel is available, though manufacturers recommend service intervals after extended use and some units include runtime limits to protect the engine.
- What maintenance does a standby generator require? You should schedule annual service that includes an oil change, air filter replacement, spark plug inspection, and battery test, along with checking the transfer switch operation and fuel connections.
- Why does the generator need a transfer switch? The transfer switch prevents your generator from sending power back into utility lines, which protects line workers and prevents damage to the generator when grid power returns.
- How is the generator positioned on the property? The unit must be placed on a level concrete or composite pad with clearance for airflow and exhaust, positioned to meet local setback rules and avoid obstructing windows or intake vents.
