Power outages can be a major inconvenience, leaving you without essential appliances and lighting. Connecting a portable generator to your house can provide a reliable backup power source, ensuring you’re not left in the dark. In this article, we’ll explore the methods and steps involved in hooking up a portable generator to your house.

Section 1: Types of Generator Connections
When it comes to connecting a portable generator to your house, there are two primary methods: using a transfer switch or installing an interlock kit. These methods ensure a safe and efficient transfer of power from the generator to your home’s electrical system.
Subsection 1.1: Using a Transfer Switch
A transfer switch is a device that connects your generator to your house’s electrical panel. It allows you to easily switch between utility power and generator power. The transfer switch ensures that only one power source is active at a time, preventing backfeeding and protecting utility workers from unexpected electrical currents.
To use a transfer switch, you’ll need to follow the manufacturer’s instructions for installation. Generally, the process involves connecting the generator to the transfer switch and then connecting the transfer switch to your electrical panel. When a power outage occurs, you simply switch the transfer switch to the generator position to activate the backup power supply.
Subsection 1.2: Installing an Interlock Kit
An interlock kit is another option for safely connecting a portable generator to your house. It’s a device that prevents the main electrical panel’s main breaker and the generator breaker from being in the “on” position simultaneously. This eliminates the risk of feeding power back into the grid and ensures that only one power source is active.
Installing an interlock kit involves mounting it onto the electrical panel and connecting the generator breaker to the interlock device. This way, the main breaker and generator breaker cannot be turned on simultaneously. Interlock kits are a cost-effective solution, but they may require some electrical knowledge for proper installation.
Section 2: Necessary Equipment and Precautions
Regardless of the method you choose, there are some necessary equipment and precautions to consider:
- Generator: Ensure you have a suitable portable generator with sufficient wattage to power your essential appliances.
- Extension Cords: Use heavy-duty extension cords to connect the generator to your house. Make sure they’re rated for outdoor use.
- Grounding: Properly ground both the generator and your house’s electrical system to prevent electrical shocks.
- Electrical Load Management: Calculate the total wattage of the appliances you want to power and avoid overloading the generator.
Section 3: Step-by-Step Connection Process
Connecting a portable generator to your house involves several steps:
Subsection 3.1: Location
- Location: Place the generator outdoors in a well-ventilated area, away from windows and doors.
Subsection 3.2: Extension Cord
- Extension Cord: Connect the generator to the house using a suitable extension cord.
Subsection 3.3: Powering Appliances
- Powering Appliances: Start the generator and power essential appliances one by one, avoiding overloading.
Subsection 3.4: Transfer Switch or Interlock Kit
- Transfer Switch or Interlock Kit: If using a transfer switch, switch it to the generator position. If using an interlock kit, ensure the main breaker is off before turning on the generator breaker.
Subsection 3.5: Using Power
- Using Power: Enjoy your backup power, but be mindful of your generator’s fuel levels and avoid overuse.
Section 4: Safety Measures and Tips
Safety is paramount when connecting a generator to your house:
- Backfeeding Risk: Backfeeding, where generator power flows into the utility lines, can be dangerous for utility workers. Use a transfer switch or interlock kit to prevent backfeeding.
- Carbon Monoxide Poisoning: Generators produce carbon monoxide, a colorless and odorless gas that can be lethal. Always operate the generator outdoors, far from windows and vents.
- Grounding: Properly ground your generator to prevent electrical hazards.
- Extension Cord Use: If using extension cords, ensure they’re rated for outdoor use and are in good condition.
Section 5: Benefits of Professional Installation
While DIY installation is possible, hiring a professional for generator connection offers several benefits. Professionals are well-versed in electrical codes and can ensure a safe and compliant setup. They can also provide expert advice on generator sizing and placement, giving you peace of mind during power outages.
Section 6: Conclusion
Hooking up a portable generator to your house is a valuable solution for maintaining power during outages. Whether you choose a transfer switch or an interlock kit, following safety guidelines and precautions is essential. By ensuring proper installation and operation, you can rely on your generator to provide backup power when you need it most.
Frequently Asked Questions
Q1: Can I connect my generator directly to my house without a transfer switch or interlock kit?
Connecting a generator directly to your house without a proper transfer switch or interlock kit is not recommended. It can lead to backfeeding, posing risks to utility workers and your home’s electrical system.
Q2: Can I power my entire house with a portable generator?
The wattage of your generator will determine how many appliances you can power simultaneously. It’s best to prioritize essential appliances to avoid overloading the generator.
Q3: Can I install a transfer switch or interlock kit myself?
While it’s possible to install a transfer switch or interlock kit yourself, it’s recommended to hire a licensed electrician for proper installation to ensure safety and compliance with electrical codes.
Q4: What’s the difference between a transfer switch and an interlock kit?
A transfer switch connects the generator to your electrical panel and allows you to switch between utility power and generator power. An interlock kit prevents the main breaker and generator breaker from being on simultaneously, ensuring only one power source is active.
Q5: Can I connect a generator to my house’s wiring directly through an outlet?
No, connecting a generator to your house’s wiring through an outlet can be dangerous and is not recommended. It can lead to backfeeding and electrical hazards. Use proper transfer switches or interlock kits for safe connection.
Q6: Can I run my generator indoors if I have proper ventilation?
No, running a generator indoors, even with ventilation, is extremely hazardous due to the risk of carbon monoxide poisoning. Always operate generators outdoors in well-ventilated areas.
