Reliable Backup Power Starts with Professional Installation
When the power goes out, your generator shouldn’t be something you hope works—it should be something you know will work. At Principle Electric, we don’t just install generators; we build dependable systems that fit your space, your usage, and your long-term needs.
As a locally owned company based in Centennial, we know how Colorado’s weather and power grid can be unpredictable. That’s why every install starts with a conversation, not a sales pitch. We take the time to understand how you use power, what you want to protect, and how to make sure your generator is there when it matters most.

FAQs About Generator Installation
Do I need a permit for generator installation in Colorado?
Yes, and we handle that for you. As licensed electricians, we make sure your system is installed to code and all permits are properly filed with your local municipality. You won’t have to worry about inspections—we take care of it.
Do you only install Generac generators?
We’re certified Generac installers, but we’re happy to discuss other trusted brands as well. If you already have a system in mind, we can evaluate whether it fits your power needs and local code requirements.
What’s the difference between a portable generator and a standby generator?
Portable generators are great for short-term, limited use, but they require manual setup, fueling, and plugging in each time. A standby generator is permanently installed and connects directly to your electrical system. It kicks on automatically during an outage and powers key systems until utility service returns.
Can a generator power my whole home, or just the essentials?
It depends on the size of the generator and what you want to keep running. Some homeowners choose to back up just essentials like the fridge, furnace, and Wi-Fi, while others go for full-home coverage. We’ll help you decide what makes sense based on your goals, budget, and available electrical capacity.
How do I know what size generator I need?
We start every installation with an on-site walk-through and load calculation. That means we’ll assess what systems you want to power—like your HVAC, appliances, internet, or medical devices—and recommend a generator that can handle the load safely and efficiently.
