"The crew very polite and informative. The whole house generator installed in one day and my place was left clean. The installation project was done in a cosmetic pleasing manner and no ugly pipes or wires are visible. I was given a detailed cost of the project and kept informed at all times. It was not the lowest bid but the work was excellent and I am very happy with the finished project. The office staff are very helpful and their excellent service and detailed bid is why I chose to go with LT Generator."

"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."

"William and his team did a fantastic job upgrading our meter panel. They took care of all the permits and had the job done on time and on schedule. They were extremely communicative throughout the entire process and I would use them for all electrical services in the future."

"I can't recommend Ken Johnson and his team, enough. They gave me a reasonable rate for a brand new electric panel and installed it in only a couple of hours. They even made sure to keep my refrigerator hooked up to power so it stayed cool. Of course, they are following Covid protocols, and were very efficient in their time. They did a really good job on the panel. I would absolutely hire these gentlemen again."

"I recently had Narek install a Tesla wall connector in my garage in Los Angeles, and I could 't be happier with the service I received. Narek was not only professional and knowledgeable, but he also got the permit required for the installation very quickly. He arrived on time and took the time to explain the installation process and answer any questions I had. The installation itself was done quickly and efficiently, and Narek made sure to clean up after himself once the job was complete. He also took the time to show me how to use the wall connector and ensure that it was working properly before he left. Overall, I would highly recommend Narek to anyone looking to install a Tesla wall connector. His professionalism, attention to detail, and expertise made the process easy and stress-free, and I am thrilled to now have a reliable and efficient way to charge my electric vehicle at home."

Generator Install questions, answered by experts

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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. 

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.
