 Trustindex verifies that the original source of the review is Google. Alliance Electrical was nothing but professional during the entire job. They arrived on time, made me feel extremely comfortable by following COVID protocols and ensured me that they are taking all steps to ensure the safety of my family. They took the time to prep the space, had proactive conversation about the project I wanted to complete and finished the whole job in a timely manner. The final project looks absolutely amazing and they left the work space clean following there work. The price was extremely reasonable for the level and quality of work completed. I would highly recommend them and will definitely be calling on their services for future projects.

I contacted Jessi and got a quick response.  His communication was great and informative. Our living room looks fantastic with the new lights. We will be hiring him again for more electrical work!

Generator Installation Process

Plan the backup load before installing the backup system.

Generator work should start with what you need to keep running. From there, the panel, transfer equipment, wiring route, and installation plan become much clearer. Some backup-power projects also require an electrical panel or service upgrade before connection.

1. Project Details

We collect your site details, generator type, panel photos, backup power goals, critical loads, and any project notes.

2. Review

We review your panel, service, desired backup circuits, generator location, wiring path, transfer equipment needs, and practical install options.

3. Plan

We identify the right electrical approach: transfer switch, generator panel, inlet, critical-load panel, or standby generator wiring support.

4. Install

We complete the electrical work cleanly, safely, and with professional communication through the job.

Why Alliance

Backup power needs safe transfer and clean electrical planning.

Generator work is not just another circuit. The system has to protect people, equipment, utility workers, and the building. Alliance focuses on safe wiring, proper transfer, clean layout, and practical backup-load planning.
