Generator testing, fuel storage, and transfer switch operation
Power outages aren't a matter of if — they're a matter of when. Whether it's a PSPS event, a winter storm, or grid overload, the businesses and homeowners who weather it best are the ones who prepared before it happened.
Visual inspection — check for leaks, loose connections, debris, pest activity. Verify fuel level and battery condition.
Exercise under load for 30+ minutes at minimum 30% load. No-load exercise causes wet-stacking.
Manually initiate transfer. Verify switch transfers cleanly, generator carries load, retransfer works.
Apply resistive load to 100% rated capacity. Check voltage regulation, frequency stability, exhaust temps.
Treat with biocide and stabilizer. Test fuel annually for water contamination and microbial growth.
Verify pipeline pressure and regulator operation. Earthquake shutoff valves required in CA.
Check tank level weekly. Minimum 250-gallon tank for residential, 500+ for commercial.
Everyone who might need to operate the system should know these steps. Post them near the transfer switch and review quarterly.
Verify utility power is truly out — check neighbors and utility outage map
Start generator and let it warm up for 2 minutes minimum
Verify generator voltage and frequency are stable (nominal ±5%)
Initiate transfer to emergency position
Verify critical loads are energized
Monitor generator during operation — oil pressure, coolant temp, voltage
When utility returns, let it stabilize 5 minutes before retransfer
Return transfer switch to normal (utility) position
Let generator run 5 minutes cooldown before shutting down
A generator that hasn't been tested is a generator that won't start. We offer emergency preparedness evaluations, maintenance contracts, and 24/7 emergency service.
