What Size Generator Do I Need?
One of the most common questions homeowners ask is what size standby generator is needed to power their home during an outage.
​
The correct generator size depends on several factors, including the size of your home, the appliances you want to power, and whether you want to run essential circuits or the entire house.
​
Many homes in Hampton Roads are well served by 18kW–24kW standby generators, but the correct size should always be determined by a professional load calculation.
At Wire All Mechanical, we evaluate your electrical system and power needs to recommend the right generator for your home.

How Automatic Backup Power Works
When a power outage occurs, a standby generator automatically restores electricity to your home within seconds.
​
A device called an automatic transfer switch constantly monitors utility power. If the system detects a power outage, it signals the generator to start.
​
Within moments, the transfer switch safely disconnects your home from the utility grid and switches power to the generator. Once utility power is restored, the system automatically switches back and shuts the generator down.
​
This process happens automatically, so homeowners don’t need to go outside, start equipment manually, or worry about extension cords.
​
With a professionally installed standby generator, your home stays powered safely and reliably during unexpected outages.
