"I recently had a generator installed by Emerge Electrical, and I couldn’t be more impressed with the service I received from start to finish. From the initial consultation to the final installation, the team demonstrated professionalism, expertise, and a genuine commitment to customer satisfaction. The technicians arrived promptly and took the time to explain the entire process to me, answering all my questions about generator size, maintenance, and functionality. They worked efficiently and carefully, ensuring that the installation was seamless and met all safety standards. The team also took great care to keep my home clean, laying down protective covers and cleaning up after themselves. What really stood out to me was their attention to detail. They made sure the generator was properly tested and walked me through how to operate it, providing useful tips for maintenance and troubleshooting. The generator itself has been running smoothly ever since, giving me peace of mind during power outages. I highly recommend Emerge Electrical for anyone in need of electrical services or generator installation. Their professionalism, expertise, and exceptional customer service set them apart from others in the industry. They’ve earned my trust, and I won’t hesitate to call them for any future electrical needs."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.
