What Is a Generator Transfer Switch — and Why You Need One
A transfer switch safely connects your backup generator to your home's electrical panel, isolating it from the utility grid so power can't "backfeed" and endanger line workers. In the Chicago suburbs, proper generator installation with a code-compliant transfer switch isn't optional — it's required for safe, legal operation. Alta Property Services, a licensed and insured electrical contractor in Addison, handles the full job from panel assessment to final inspection.

Generator Transfer Switch Mistakes to Avoid
- "Suicide cord" backfeeding. Plugging a generator into an outlet without a transfer switch can kill line workers and start fires. Never do it.
- Undersizing the switch. A switch that can't carry your critical loads leaves you in the dark anyway. We size it to your home.
- Skipping the permit. Unpermitted electrical work can void insurance and fail at resale. We handle it properly.
- DIY installs. Transfer switches tie directly into your service panel — this is licensed-electrician territory, full stop.
