"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!"

"B&C Electric did a great job. Robert Burns came to my house after another electrician from another company installed a Tesla charger. For the next 4 weeks we had trouble with different areas of our house losing power. I called this initial electrician back to fix the problem. He came and did some work but the power outages continued. That's when I said enough is enough and called Robert at B&C electric. He came and did a thorough evaluation of my sub panel. He found that the breaker switch installed by the other company was not only cheap but not wired correctly. Robert installed a new breaker switch and I have not had any trouble since. Robert explained everything to me and showed me what he was doing. The best electrician I have used, hands down. I will use him again!"

"They installed a 50 amp plug in my garage to connect an EV charger. I was afraid that the installation may require a panel upgrade. But he made it work without the upgrade. The price was good and the work was done quickly. Great job. Would hire them again."

"I had Mister Sparky come out to install a ceiling fan at my house and the experience was great from start to finish. The technician was professional, showed up on time, and got everything installed quickly and cleanly. You can tell they take pride in their work and pay attention to the details. If you’re looking for a reliable electrical company that does quality work, I’d definitely recommend Mister Sparky."

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

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.
