In this guide, we will walk you through the process of installing a Generac generator transfer switch, step by step.

Before You Begin

Before diving into the installation process, there are several crucial considerations to keep in mind:

1. Check Local Regulations

First and foremost, you should verify with your local codes office whether it is legal and safe for you to perform the transfer switch installation.

Some locations require that this work be done by a professional electrician or mandate an inspection after installation. Complying with local regulations is essential to ensure your safety and that of your property.

2. Prepare Your Setup

To start the installation, you need to prepare the following items:

Generac automatic standby generator
Generac pre-wired automatic transfer switch
Screwdriver

Contact your power provider: Your power provider will need to disconnect the service to your home and remove your meter, so be sure to get in touch with them to make the necessary arrangements.

Step-by-Step Installation Guide

Now, let’s walk through the process of installing a Generac generator transfer switch. Ensure that you follow each step carefully to complete the installation safely and effectively.

1. Position the Generator

Select a suitable location for your Generac generator, typically outside and near the electrical meter. The generator should be placed where it has easy access to fuel, proper ventilation, and clear of any obstructions.

2. Mount the Transfer Switch

Mount the Generac transfer switch box on the wall using the provided screws and pre-drilled holes in the metal. Ensure it is securely attached.

3. Remove the Meter Cover

The next step involves removing the cover from your meter base. You can do this manually or by using a screwdriver, depending on how it’s secured. Once removed, you will gain access to the internal wiring.

4. Disconnect the Wiring

Inside the meter base, you will find a wire that runs from your home to the base, supplying electricity to your property. Carefully unplug this wire from the base. Ensure that you take precautions to handle the wiring safely.

5. Locate the Knockout

In the space where the meter used to be, you’ll find a knockout – a square or rectangular piece of metal with holes in it. Unscrew the screws that hold the knockout in place.

6. Connect the Wiring

Take the wire that you disconnected earlier and run it through the hole in the knockout. Now, connect it to the commercial output conduit on the Generac automatic transfer switch. Once the connection is secure, replace the knockout and secure it back into place with the screws.

7. Connect the Transfer Switch to the Meter Base

Locate the wire connected to the automatic transfer switch’s commercial input conduit. Run this wire back to the commercial output conduit on the meter base. After making the connection, close and secure the cover of the meter base, ensuring everything is in place and properly secured.

8. Verify Generator Connection

Ensure that the pre-wired connection on the generator is still connected to the accessory input conduit on the Generac automatic transfer switch.

9. Inspection and Reconnection

If local regulations require it, contact your local building codes office for an inspection. Once your installation is approved, you can have your electricity reconnected. It’s crucial to adhere to inspection requirements to ensure that your installation complies with safety standards.

Warning: Electrical Safety

Working with electricity can be extremely dangerous. If you are not comfortable and knowledgeable about electrical wiring, it is strongly recommended to have a professional electrician handle the installation. Your safety and the safety of your property should be the top priority.

Professional Help and Its Importance

Installing a Generac generator transfer switch is a complex electrical task that requires careful planning and execution.

If you are not comfortable working with electrical systems, it’s strongly recommended to hire a professional electrician to perform the installation.

Electrical work can be hazardous, and improper installation can lead to dangerous situations, electrical fires, or damage to your generator or property.

Here are a few additional points to consider:

Permits and Inspections: Always check local regulations and permit requirements. In many places, you’ll need to obtain the necessary permits and have the installation inspected to ensure it complies with safety standards.
Generator Location: Choose a generator location that complies with local zoning regulations, and ensure it’s well-ventilated, easily accessible for maintenance, and away from flammable materials.

Sizing the Generator: Ensure that your generator is appropriately sized to meet your electrical needs. It should be capable of supplying power to critical circuits during an outage.
Proper Grounding: Grounding is crucial for safety. Follow the manufacturer’s recommendations for grounding the generator and transfer switch.
Testing: Once the installation is complete, conduct thorough testing to ensure that the system functions correctly. Test it under different scenarios, such as a power outage and when utility power is restored.

Conclusion

In conclusion, installing a Generac generator transfer switch is a critical step in ensuring reliable backup power during outages.

While it is possible to perform the installation yourself, it’s essential to prioritize safety and compliance with local regulations. For many, hiring a professional electrician is the safest and most reliable option, as electrical work can be complex and potentially dangerous.

Properly installed transfer switches are key to safeguarding your home or business during power interruptions, and adhering to safety standards and regulations is paramount in this process.
