"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."

"Electrician did not pull permit for this kind of work as required and after the work was completed, I asked and he said the permit wasn't really necessary. Turns out a permit is required and I assumed when agreeing to the work that all mandatory government requirements would be followed before starting work."

Our Big Frog, James Crofutt, after having worked for the larger electrical companies, decided the industry needed a change so, Big Frog Electric jumped in with a splash in 2011. His 21 years of experience in the field backed with numerous certifications and licenses makes our know-how hard to beat. Having spent these years directly interfacing with customers, James understands that customers priorities include personable service, fast response times, the ability to trust that the job is being done right, and professionalism. At Big Frog Electric we do not have commissioned salesman, just electricians that have your safety as their #1 priority and not their pockets! We fill a void in the disappearing art of craftsmanship, integrity and character in the electrical contracting business. Our Frogs are fully dedicated to the electrical trade, its research, industry knowledge and are actively on the edge of new technologies. Each Tadpole (new hires) we recruit displays optimal craftsmanship, knowledge, courtesy and professionalism with each project - from inspection to conception to completion. You can have peace of mind with Big Frog Electric on the job. Big Frog Electric is a family-owned, owner-operated, electrical service company that appreciate the communities we service and gives back where we can. One way that Big Frog Electric gives back is by offering a special discount to all of our public school teachers, veterans, seniors and first responders. Award winning .

Generator Install questions, answered by experts

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

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. 

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
