How Should I Shut Off My Generator After Power Is Restored?

When utility power returns, it is important to shut down the generator in the proper order to safely transition your home back to utility power.

Follow the steps below:

Step 1: Turn Off the Transfer Switch or Interlock Breaker

First, switch the main breaker on the transfer switch or interlock panel to the OFF position.

This disconnects the generator from your home’s electrical system and prevents power from feeding into the panel.

Step 2: Turn the Generator Breaker OFF

Next, locate the generator’s main breaker on the control panel and switch it to the OFF position.

This stops power from flowing to the outlets and connected circuits.

Step 3: Shut Down the Generator

Turn the key switch to the OFF position or press the push-button start/stop button to shut the generator down.

Allow the engine a moment to fully power down.

Step 4: Shut Off the Fuel Supply (If Using Propane or Natural Gas)

If the generator is operating on propane or natural gas, turn off the fuel supply valve.

Allow the generator to run until the remaining fuel in the system is consumed and the engine stops.

Step 5: Disconnect Power Cords

Once the generator has completely stopped running, you can safely disconnect the generator power cord or adapter cables.

Important Safety Note

⚠ Always allow the generator to fully power down before disconnecting cords or performing maintenance.

Following the correct shutdown procedure helps prevent:

• Electrical hazards

• Equipment damage

• Backfeeding into your electrical system

Common Questions

Do I need to turn the generator breaker off before shutting down the engine?

Yes. Turning off the generator breaker first removes electrical load from the generator before shutting down the engine.

Why should I shut off the fuel supply for propane or natural gas?

Closing the fuel supply allows the generator to burn off the remaining fuel in the line, which helps prevent fuel buildup in the system.
