What it covers
Generator options for Petaluma homes
Generator installation is the wiring that lets a generator power your home without touching the PG&E grid. The key part is the transfer switch or interlock that separates the two sources.
- Standby generator: a fixed unit that starts on its own when power drops.
- Portable generator inlet: an outdoor inlet and interlock that let a portable unit feed chosen circuits.
- Automatic transfer switch: moves the load to the generator and back without you touching the panel.
- Essential-loads subpanel: a smaller panel holding only the circuits you need during an outage.
Why Petaluma homes add them
PG&E uses Public Safety Power Shutoffs during extreme fire weather. During a 2019 shutoff, 4,296 Petaluma customers lost power. Homes with well pumps, medical equipment or home offices feel those outages most.
Planning
Sizing and placing a generator
The electrician starts with a list of what must run during an outage. That list sets the generator size and the transfer equipment.
A standby unit needs a level pad, clearance from windows, doors and vents, and a fuel supply. Natural gas or propane lines are often run by a separate licensed contractor.
Some panels have no room for an interlock or transfer equipment. In that case the plan may include an electrical panel upgrade in Petaluma first.
Before you call
- Circuits you need during an outage
- Portable or standby
- Gas, propane or gasoline fuel
- A photo of the main panel label
Safety and permits
Backfeed, permits and inspection
Backfeed is power flowing from a generator back onto utility lines. It happens when a generator is plugged into a wall outlet, and it can injure PG&E crews working on lines they believe are dead.
A licensed electrician confirms which permit the installation needs, pulls it from the City of Petaluma Building Division and books the inspection.
A generator is only as safe as the grounding behind it. See grounding and bonding in Petaluma for that part of the system.
Generator safety rules
- Run portable units outdoors only.
- Keep them away from doors, windows and vents.
- Use a transfer switch or interlock, never a wall outlet.

Generator Installation in Petaluma: FAQs
Talk to a licensed electrician
Describe the problem and your ZIP. We will connect you with a local pro in Petaluma.
Call (815) 456-4349What size generator do I need for a PSPS outage?
It depends on the circuits you want to run. A refrigerator, lights and internet need far less than a whole house with a well pump. The electrician sizes it from your list.
Is an interlock as safe as a transfer switch?
Yes, when it is the approved interlock for your panel and installed by a licensed electrician. Both stop the generator and PG&E from feeding the house at the same time.
Do I need a permit to install a standby generator in Petaluma?
A fixed standby generator needs permitted electrical work. The electrician confirms the full permit list with the Building Division and pulls it.
