"Ellenwood Electric responded to a request for quote to upgrade our existing 100 amp electrical panel to a 200 amp electrical panel and was onsite within the week to perform a detailed walkthrough to prepare a scope of work and quote. Once the work was approved a date was scheduled and vendor Mark from Ellenwood reached out directly to provide scheduled dates and ask if there were any questions. On the the two days of install Luis and Diego were promptly on time and performed the entire scope of work and answered questions that we had about the process. Overall Ellenwood Electric was 100% professional and pleasant and would work with them again for all future electrical needs."

"Anthony was very attentive to my project on an old building. He sought out a safe and viable solution to change out an old fuse box and relocate with a new breaker box. He was quick with a response to my request, inspection and quickly gave a solution with a quote. Once I accepted, he scheduled my work right away. He was also prompt on the day of installation and did the work professionally and quickly. I recommend A & A Electric and I would even recommend Anthony to my family and friends. - Pastor Jeff"

"My house generator was serviced and the battery replaced. Everything about the experience was excellent. Mike, the technician, called when he was on the way, worked with me and my restrictions because of Covid, he was punctual, professional, explained thoroughly the work he did. For 8 years Anderson has serviced my generator and when needed during electric outage, my generator keeps my house running until the electric service is restored! Thank you for reliable service!"

"Mike at MDL electrical went above and beyond the call of duty. We were facing a potential major electrical issue during a very busy evening in the middle of service. He responded to the call and even took the time to stop and check out the issue to ensure our minds were put at ease. He came back the following day promptly and repaired the situation with efficiency and ease. We would highly recommend MDL & Mike and take comfort in knowing we have a reliable electrician to call on! Thank you so much Mike! We appreciate you! Molly & Living Roots Winery Crew"

Electrical questions, answered by experts

A C-wire is typically blue, but don’t rely on colors to find which wire is which when it comes to thermostat wires. The C-wire may also be black, brown, or purple. Instead, if you’re looking for the C-wire, look at the thermostat panel for a wire connecting to “terminal C,” or call in a pro to help you look for a C-wire.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Unless you’re a licensed electrician, you should not DIY any electrical work in your home. Working with wires and electricity is potentially dangerous to both you and the structure you’re working on, and it could lead to house fires or electric shock if you’re not 100% sure what you’re doing. There’s a big difference between changing a light switch cover and rewiring an entire home. If you’re staring down a potentially difficult electrical job, give a pro a call.

Upgrading your electrical panel is often worth the cost for safety, improved electrical performance, and potential long-term savings. A primary benefit is preventing electrical fires and other hazards from a malfunctioning panel, ensuring your household's safety. An upgraded panel also provides a steady flow of electricity, eliminating issues like flickering lights and frequently tripped breakers. It allows you to connect additional appliances without overloading the system, which is especially beneficial for older homes with 100-amp service that are prone to overheating. If you run large appliances like central air conditioning, heating systems, hot tubs, or saunas, you might consider upgrading to a 300- or 400-amp service to meet the higher electrical demand. Furthermore, an upgrade can lead to long-term savings on energy bills and potentially lower insurance costs.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.
