Power outages have become pretty common, which is why more households are investing in generators. Installing a home backup generator sounds pretty straightforward. You have to choose an appropriate generator type, choose a location, connect electrical wires, and set up a fuel connection.
Unfortunately, the actual process involves many moving parts and can be incredibly complex. If you’re tempted by the idea of DIYing a generator installation, this guide is for you.
Let’s consider whether you can install a backup generator yourself and why professional installation matters.
DIY Generator Installation
Many homeowners, especially those comfortable with tools and weekend home renovation projects, consider installing a backup generator by themselves. And they have their reasons. DIY generator installation allows you to save on labor costs, have complete control over the installation process, and gain personal satisfaction.
For small and portable generators, DIY installation is generally safe and manageable. This is especially true with plug-and-play models. Just place near windows or doors at a safe distance and run heavy-duty extension cords to appliances. You can connect it to an outdoor power inlet box or directly to appliances.
But for standby and whole-house generators, installation isn’t as straightforward as YouTube tutorials might have led you to believe.
The Complexity Behind Generator Installation
Installing a home backup generator is more than just placing a unit next to your home and plugging it in. A generator will power your entire house during an outage, which makes installation a layered process.
Here are the common steps of a home generator installation:
Placing generator unit: A backup generator requires a secure, level concrete pad for mounting to handle the weight and vibration. The location must comply with local clearance regulations.
Automatic transfer switch: The generator is connected to your home’s main panel with an automatic transfer switch.
Fuel setup: The generator is connected to a natural gas or propane line. The gas or fuel line must be properly sized and leak-free.
Managing control panel: The control panel serves as the command centre and ensures connection between the generator and the transfer switch. This is necessary for automatic start/stop.
Maintenance and inspection: The entire process of installing a generator requires multiple permits from local authorities, including electrical, building, and fire zoning permits.
The Risks of Installing a Generator By Yourself
In addition to being complex, the installation process can pose several risks for homeowners. Improper generator installation can lead to:
- Backfeeding (electricity flowing back to utility lines)
- Carbon monoxide poisoning
- Fire hazards
- Electrical wiring malfunctioning
- Lack of compliance
Why Professional Backup Generator Installation Makes Sense
While you can try to install a backup generator yourself, it is generally not recommended. Professional backup generator installation makes more sense. Here’s why:
- They assess your home’s power load, including HVAC systems, kitchen appliances, and lighting, before recommending a generator unit.
- They follow local codes and have the necessary permits to install a backup generator safely.
- They are licensed and have years of experience.
- They handle every aspect of generator installation, including delivery, placement, and securing the unit in accordance with local codes.
To sum up, homeowners can install portable generators themselves. But for standby and whole-house generators, professional services are important.
