"Sergio did a fantastic job! Very happy with the clean install of my tier 2 charger and he added a plug down below my panel. Would recommend for any sort of EV charging installs! Clear communicator, showed up when he said he would and his services were well-priced!"

"Highly Recommended! We have hired Zero Electric to do several jobs at our apartment complex including installing a generator, EV chargers, new panel, and even installing recessed lighting in the units. They handled all aspects of the projects and had top notch communication throughout. The team has always been quick and professional. We will continue using Zero Electric for our electrical needs."

"Ricardo is the best electrician I?ve ever hired. Was very professional and friendly to talk to. Honest pricing for a meter panel upgrade. Did what he said he was going to. Also checked out some lighting fixtures I wanted to get installed in my home as I?ve had several quotes and they were just outrageously priced but he gave me the best price out of 6 electricians! Will definitely hire Rick for all my future electrical needs!!"

"They were great from the start. Setting up the appointment was easy. They let me know through text when the electrician would arrive. The electrician was very professional and was able to explain things to me clearly in a way I would understand. He gave me a fair price and there were no surprise charges."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
