How to Connect a Generator to Your Home Safely

When the power goes out, a generator can be a lifesaver. Whether it’s keeping your lights on during a storm or powering essential appliances during an outage, a generator gives you peace of mind. But connecting a generator to your home incorrectly can be dangerous, leading to fires, electrical shocks, or damage to your appliances.

Here’s what every homeowner should know about connecting a generator safely.

1. Choose the Right Type of Generator

Before anything else, make sure you have the appropriate generator for your needs:

• Portable Generator: Runs on gasoline or propane and is mobile. Great for powering a few circuits or appliances.

• Standby Generator: Permanently installed and hardwired to your home. Can power your entire home automatically during an outage.

2. Never Plug a Generator Directly into a Wall Outlet

This is called “backfeeding” and it’s extremely dangerous. Backfeeding can:

• Electrocute utility workers repairing power lines

• Damage your home’s electrical system

• Void insurance coverage if an accident occurs

Instead, use one of these safe connection methods.

3. Use a Transfer Switch

A transfer switch is the safest and most effective way to connect a generator to your home. It safely isolates your generator from the utility lines and allows you to power selected circuits without risk.

Types of Transfer Switches

Manual Transfer Switch

• Requires you to flip a switch when the generator is running

• Lets you select which circuits to power (e.g., refrigerator, lights, furnace)

• Pros: Lower cost, reliable, simple

• Cons: Must be activated manually

Automatic Transfer Switch (ATS)

• Detects a power outage automatically and starts your standby generator

• Switches your home’s circuits to generator power instantly

• Returns to utility power automatically when the grid is restored

• Pros: Hands-free, ideal for whole-home coverage, great for medical equipment or home offices

• Cons: Higher upfront cost, requires professional installation

  
  

Why a Transfer Switch Is Important

• Safety: Prevents dangerous backfeeding

• Appliance Protection: Avoids power surges that can damage sensitive electronics

• Code Compliance: Often required by local building codes

• Convenience: Lets you control exactly which circuits get powered

  
  

Installation Tips

• Always hire a licensed electrician for installation

• Ensure the switch is sized for your generator and home circuits

• Label circuits clearly for quick operation during outages

  
  

4. Keep Your Generator Outside and Well-Ventilated

Never run a generator inside your home, garage, or basement. Generators produce carbon monoxide, which is deadly. Always:

• Place the generator at least 20 feet from your home

• Keep it on a dry, stable surface

• Avoid running it in enclosed or partially enclosed areas

  
  

5. Use Heavy-Duty, Outdoor-Rated Extension Cords

If you’re using a portable generator to power appliances directly:

• Choose cords rated for the wattage of your appliances

• Make sure cords are outdoor-rated and free of cuts or damage

• Plug appliances directly into the generator—never into wall outlets

  
  

6. Turn Off Appliances Before Connecting

To prevent surges:

• Turn off major appliances before connecting the generator

• Start the generator first, then turn on appliances one at a time

  
  

7. Follow Manufacturer Instructions and Local Codes

Every generator comes with a user manual—read it! Also:

• Check local building codes for generator installation requirements

• Standby generators almost always require professional installation

  
  

Final Thoughts

Connecting a generator safely protects your family, your appliances, and utility workers. While a portable generator can be useful in emergencies, nothing beats the safety, convenience, and reliability of a professionally installed standby generator with a transfer switch.
