Generator Installation and Setup

Whole-Home & Portable Generator Installation in Phoenix and Maricopa County

Whether you’re protecting your home during monsoon season or keeping your business running during outages, a properly installed generator gives you the peace of mind you need. At Extra Electrical Inc., we provide complete generator installation services for both whole-house standby systems and portable generator setups with transfer switches. Our licensed electricians ensure every installation is safe, efficient, and fully code-compliant.
“A generator is only as reliable as the installation behind it. We take care of everything—from sizing to wiring to testing—to make sure it’s ready when you need it most.” — David Gomez, Owner, Extra Electrical Inc.

Why Proper Generator Setup Supports Electrical System Health

Generators integrate directly with your home or business’s electrical panel. A poor or unsafe installation can backfeed power, damage your system, or pose serious safety risks. Our installations include correct sizing, transfer switch integration, grounding, and load management to protect your entire electrical infrastructure and ensure uninterrupted performance during outages. Whether it’s a portable generator with a manual transfer switch or a whole-home automatic system, proper setup is critical.

Generator Installation FAQs

What’s the difference between a whole-home generator and a portable one?
Whole-home generators are permanently installed and automatically power your home during outages. Portable generators are manually started and require an inlet box and transfer switch to safely connect to your panel.
Do I need a transfer switch for my generator?
Yes. Transfer switches isolate the generator from the utility grid and prevent dangerous backfeeding. We install both manual and automatic models.
Can you install a generator I already purchased?
Absolutely. We can install customer-provided generators and ensure the setup meets code and functions safely.
Do you handle permitting for generator installs?
Yes. We handle all permits, inspections, and utility coordination to ensure your generator is safely and legally installed.
