How long does the generator installation take? What should I expect on day of install?

Generator Installation Duration and Expectations

The duration of a generator installation typically takes a day or less, depending on the type of installation. Below are the details for partial and whole house installations.

The typical schedule is:

  • Arrival on site by 8:00 AM
  • Power restored by 2:00 PM or 3:00 PM
  • Testing completed by 4:00 PM or 5:00 PM

The primary difference between partial and whole house installations is the duration of the power outage, though the overall job duration remains similar.

Partial House Installation

In a partial house installation, selected circuits are moved to a sub-panel controlled by the generator. Each circuit takes about 20 minutes to transfer, minimizing the downtime of the main panel.

Whole House Installation

For whole house generators, the main service must be intercepted before reaching the main panel, resulting in a full power shutdown. The power outage typically lasts 3 to 6 hours.

The remainder of the installation process is the same for both partial and whole house setups.



Installation Process Overview

  1. Arrival: We arrive between 8:00 AM and 9:00 AM with a truck and trailer carrying necessary tools and equipment.
  2. Parking: Please ensure there is a parking space near the work area for ease of access and to minimize foot traffic around your home.
  3. Power Cut: We aim to cut power within 1 hour of arriving on site.
  4. Installation: Our team works efficiently, with technicians assigned to different tasks.
  5. Testing: After installation, we perform minor tests to ensure everything functions correctly.
  6. Final Demonstration: We complete the process with a full manual test of the generator and components, followed by a transfer demonstration for you.

Roles of Each Technician (Depending on Crew Size)

  • Transfer Switch Installation: One technician installs the transfer switch(es) to your electrical system.
  • Generator Setup: Multiple technicians set up the pad and generator, while another works inside the breaker panel.
  • Natural Gas/LP Installation: A technician (or multiple) will manage the gas lines, whether inside or along the exterior of the house.


Preparation Checklist

To ensure a smooth process, please:

  • Clear any spaces around the electrical panel, gas lines, and work areas before the team arrives.
  • If applicable, prepare your WiFi username and password for the technician to set up Generator WiFi Monitoring. For LTE options, no setup is needed as it's a standalone system.


Accommodations During the Install

We strive to accommodate your needs during installation. If you have any special requests or requirements, please inform us as soon as possible. Here are a few examples:

  • Preferred doors or paths for our installers to use.
  • Animals that should be kept in a safe area.
  • Medical needs requiring power during installation.
  • Essential equipment that must remain powered.

Providing this information in advance helps us better prepare and ensure a smooth installation process.
