Frequently Asked Questions
Have questions about backup generators, electrical systems, or getting ready for outages? You’re in the right place. Here are answers to the most common questions homeowners and businesses ask.
How does a standby generator work?
A standby generator automatically detects when the power goes out. Within seconds, the automatic transfer switch shifts your home or business to generator power, keeping lights, appliances, and critical systems running. Once utility power is restored, it switches back automatically.
​
What size generator do I need?
It depends on what you want to power. A smaller system can cover essentials like lights, refrigeration, and basic appliances. Larger models can run your entire home or business, including HVAC systems. We offer free consultations to determine the right generator size for your needs.
​
Can a generator power my entire home or business?
Yes, if the generator is properly sized. Whole-house and commercial generators are designed to run everything from air conditioning to heavy equipment. We’ll evaluate your property and make sure your system is built to handle your full load if that’s what you need.
​
How loud are Cummins generators?
Cummins Quiet Connect generators are designed for quiet operation, typically running at about 65 dB — similar to a central air conditioner. That makes them among the quietest standby units available.
​
What type of fuel do Cummins generators use?
Cummins standby generators run on natural gas, propane, or diesel, depending on the model and your installation. Home units often connect to your existing natural gas line, so there’s no need to worry about manual refueling.
​
How long can a standby generator run?
A generator can run as long as fuel is available. Natural gas units can run continuously during extended outages, while propane and diesel generators are limited by tank size. With proper maintenance, a generator can provide days or even weeks of power.
​
What maintenance does a generator require?
Standby generators need regular service to stay reliable. We recommend maintenance every 6 months, which includes oil and filter changes, checking the battery, and running load tests. We also offer ongoing maintenance contracts so you never have to worry.
​
What happens if my generator doesn’t start during an outage?
Most Cummins units have self-diagnostics to alert you before there’s a problem. If your generator doesn’t start, check for fuel supply, battery charge, or AUTO mode settings. If the issue continues, our technicians can quickly troubleshoot and repair the system.
