"They werenâ t able to install lighting in my brick pillars after I purchased new lights per their request. They said the pillars would probably need to be taken apart to find the problem.They did some rewriting work and it was ok."

"CD Electric was fantastic. They added electrical outlets to the interior and exterior of my home and installed an exterior light. Chase was very thorough with the estimate he provided me and completed the job in the time he said it would take. I would definitely hire them again for any future jobs and I highly recommend them to anyone else."

"Things went great with them and we are still using them. As soon as our bar is installed, they are going to finish up the electrical work. They were fast, reliable and really nice people. They were also on time. We got bids and they had the lowest bid."

Generator Install questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
