How do I test my backup generator
Brian’s bakery was dark. Completely dark. Not a romantic, dimly lit ambiance, but the kind of dark that meant a $12,000 walk-in freezer full of wedding cakes and custom orders was rapidly turning into a sugary, melted mess. A blown transformer knocked out power to the entire block, and Brian’s manual transfer switch, untested for five years, refused to engage. The resulting loss of product and customer goodwill cost him nearly $18,000 – a price easily avoided with a simple, regular generator test.
Why Regular Generator Testing Matters
Have you ever really verified your backup generator will kick in when the lights go out? It’s not enough to just hear it run during an outage. A surprising number of generators fail to operate correctly when needed due to simple neglect, fuel degradation, or mechanical issues. Think of it like a smoke detector – it needs periodic checks to ensure it will actually protect you when a fire breaks out.
What Does a Generator Test Involve?
A comprehensive test goes beyond just starting the engine. Here’s a breakdown of what you need to do, moving from simple checks to more in-depth procedures:
- Visual Inspection: Start by visually inspecting the generator for any obvious damage, loose connections, or corrosion. Check the oil and coolant levels, ensuring they’re at the proper marks.
- Fuel Check: Gasoline degrades over time. Fuel stored for longer than 6-12 months can cause starting and running problems. Ideally, use a fuel stabilizer, but at a minimum, ensure you rotate your fuel supply or completely drain and refill the tank annually.
- Battery Test: Most generators use a 12-volt battery to start. Use a voltmeter to check the battery voltage – it should be above 12.6 volts. If it’s significantly lower, the battery may need to be charged or replaced.
- Automatic Transfer Switch (ATS) Verification: This is where Brian failed. Simulate a power outage by switching off the main breaker that feeds your generator. The ATS should automatically switch over to generator power. If it doesn’t, you need to investigate the ATS itself. This might require an electrician.
- Load Test: Simply starting the generator isn’t enough. You need to put a load on it to ensure it can handle your critical circuits. Start by powering essential appliances – refrigerator, sump pump, furnace – and then gradually add more load. Monitor the generator’s voltage and frequency to ensure they remain within acceptable limits.
How Often Should You Test?
I recommend a tiered testing schedule, based on over 16 years of experience delivering managed IT and cybersecurity solutions. It’s about risk mitigation – understanding that a failed generator isn’t just an IT problem, it’s a business continuity problem.
- Monthly – Visual Inspection: A quick walk-around to check for obvious issues.
- Quarterly – Short Run Test: Start the generator and let it run for 5-10 minutes without a load. This helps keep the engine lubricated and ensures the starting system is functioning.
- Annual – Full Load Test: This is the most important test. Simulate a power outage, verify the ATS is working, and run the generator under a full load for at least 30 minutes.
Understanding the Cybersecurity Advantage
While we’re talking about keeping your business running, consider this: a functioning generator keeps your network up and running during an outage. That protects your data, your security systems, and your ability to operate critical software. It’s not just about powering lights; it’s about maintaining a secure IT infrastructure. A robust power plan – including generator testing – is a core component of a layered cybersecurity strategy.
What About Portable Generators?
The process is similar for portable generators, but without the automatic transfer switch. You’ll need to manually connect the generator to your critical circuits using appropriate extension cords, being extremely careful not to backfeed power into the utility grid (which is illegal and dangerous). The load test is even more crucial with portable generators, as you have to manually manage the load distribution.
Nevada Legal Considerations
If you’re operating a business in Nevada, remember that NRS 603A.215 requires you to maintain “reasonable security measures” to protect personal information. This extends to ensuring your business continuity plan – including your generator – is reliable, preventing potential data loss or security breaches during an outage.

Is your current backup plan “insurance-ready”?
Insurance policies often deny claims if “reasonable security measures” (NRS 603A) weren’t in place before the disaster. Don’t guess. Let our Reno-based team audit your disaster recovery plan to ensure you are fully compliant and recoverable.
