Generator installation for Bay Area homes and businesses
When the power goes out, a properly sized and installed generator keeps the lights on, the fridge cold, and your business running. We size, wire, and install it to code.
What generator installation is
Generator installation is the process of selecting, placing, wiring, and connecting a backup power source so it starts automatically or on demand when utility power fails. It includes sizing the unit to your loads, wiring it through a transfer switch, and confirming the installation meets local code.
Remnant Electric handles generator installation as a family-owned electrical contractor serving the Bay Area, California. We assess your power needs, size the unit correctly, and wire it safely so it works the moment you need it.
Why a generator matters here
The Bay Area sees outages from storms, heat waves, and grid stress. A generator keeps essential loads running, protects refrigerated food and medical equipment, and keeps a business operating instead of closing during an outage.
The key is sizing it to what you actually need to keep running and wiring it through a transfer switch that keeps your system safe.
Who generator installation is for
Any Bay Area home or business that needs power to stay on when the grid does not. The right setup depends on what you need to keep running.
Homeowners who want backup power
Keep the fridge, lights, and essential circuits running during an outage without scrambling for a portable unit.
Small businesses that cannot close
Stay open during outages so point-of-sale, refrigeration, and lighting stay up instead of losing a day of revenue.
Properties with medical or critical loads
Protect equipment that cannot go down, from medical devices to well pumps and security systems.
Anyone on an outage-prone circuit
If your block loses power often, a wired generator gives you automatic, hands-off backup instead of candles.
Sizing a generator the right way
A generator only works if it is sized to what you need to keep running. Here is a plain-language guide to what each size range typically covers, so you can picture where your project fits.
Small
7 - 10 kW
Runs essentials: lights, refrigerator, a few outlets, and a furnace or small AC. Right for keeping the basics on in a modest home.
Mid
12 - 18 kW
Covers essentials plus a water heater, well pump, and more circuits. A common fit for whole-home backup in an average Bay Area home.
Large
20 - 26 kW
Whole-home coverage including central air, larger appliances, and a second HVAC zone. Sized for bigger homes or heavier loads.
Commercial
30 kW and up
Right for businesses that need to keep refrigeration, point-of-sale, and lighting running through an extended outage.
These are general ranges. We size every generator to your actual loads with a proper load calculation, so you get enough power without paying for more than you need.
Benefits of a properly installed generator
Backup power that is safe, reliable, and ready when the next outage hits.
Power when the grid fails
A wired generator starts automatically and keeps your essentials running instead of leaving you in the dark.
Safe, code-compliant wiring
A transfer switch isolates your system from the grid, protecting your home and the crews working on the lines.
Right-sized to your loads
We calculate what you actually need to run, so the unit handles your essentials without overloading.
Built to keep working
A properly installed generator is ready for the next outage, not just the one that prompted the call.
Generator installation options
From an automatic standby unit to a portable hookup, we match the setup to your property and what you need to keep running.
Standby generator installation
A permanently installed unit that starts automatically during an outage, wired through an automatic transfer switch.
Transfer switch wiring
The safety component that isolates your system from the grid so power feeds only your property, never the lines.
Load assessment and sizing
