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 .

"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."

Generator Install questions, answered by experts

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. 

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
