How It Works

Transfer Switch Installation Process

1
Assessment & Generator Sizing

We evaluate your power needs, identify essential circuits, and recommend the correct transfer switch size and type for your generator.

2
Permit & Planning

We file for the electrical permit with LADBS. Generator installations require permits for safety and code compliance.

3
Power Off & Safe Work

We shut off power at the main panel, verify it's dead, and work using insulated tools and PPE.

4
Wiring & Mounting

Run new wiring from panel to transfer switch location. Securely mount the transfer switch and connect to panel and generator.

5
Interlock Installation & Testing

We install the mechanical or electrical interlock preventing simultaneous utility and generator connection. Test operation under load.

6
Startup & Walkthrough

We start the generator, verify transfer operation, test under load, and show you the operation procedure before we leave.

FAQ

Generator Transfer Switch FAQ

Do I need a permit for a generator transfer switch in Los Angeles? ▾
Yes — we handle all permitting and inspections as part of every installation. We manage the entire process: permit applications with LADBS (Los Angeles Department of Building and Safety), plan review submissions, coordination with LADWP for service upgrades, scheduling inspections, and obtaining the final Certificate of Completion. The permit process typically takes 3-10 business days, depending on the scope of work. Permitting ensures code compliance and protects your insurance.
Can I install a transfer switch myself? ▾
Transfer switch installation involves working with your main electrical panel and creating a permanent modification to your home's wiring. Improper installation can create backfeed hazards that endanger utility workers and violate NEC 702. Professional installation is required for safety and code compliance.

What's the difference between manual and automatic transfer switches? ▾
Manual transfer switches require you to physically move a lever or switch during an outage. Automatic transfer switches sense power loss, start the generator, and transfer load without intervention — ideal for unattended operation.

Do I need a separate panel for my generator transfer switch? ▾
Not always. We perform a free load calculation to determine if your existing panel can support a new circuit. Many homes can add a single EV charger or appliance without a panel upgrade if they have 200A service and available breaker slots. Older homes with 100A service typically need an upgrade to 200A. Factors include your current electrical load, the new circuit requirements, and local code requirements. We inspect at no cost and let you know before providing a final quote.
How long does generator transfer switch installation take? ▾
Most manual transfer switch installations take 2-4 hours. Automatic transfer switches or those requiring panel modifications may take 4-8 hours. We provide a time estimate during the quote.
