"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."

"Callahan worked me in during a busy week before the 4th even though it was a cold call. I did not know him.. The electrician was exactly on time at 8AM and he wore a mask. He did a perfect job, and went out of his way to make the wire out of site as it was installed across my garage.. Even though it took a little longer than anticipated, he still charged me the quoted price.. I will definitely call him again for all my electrical work."

"It went great! Pete and Dave were fast, friendly, and professional. They did a great job installing the ceiling fans in my rooms. They made sure to protect my belongings so that nothing was damaged during the installation. And the quote they gave me was spot on. Their prices are affordable. For what they charged to install 3 fans, another company wanted to charge me just to install 1 fan. I absolutely would highly recommend contacting Supreme. I will be definitely contact them for additional work I need to have done!"

"Pete Definbaugh and his team installed the Generac 20 KW Generator and it passed the Harford County Inspection with flying colors. Pete organized everything to include with the plumber and county inspectors as well as BGE for the gas hook up and BGE's final hookup. The generator has a great transfer switch that kick right over and he installed TWO new grounds for the setup. He paid attention to all the details and that included making sure we had Harford County Approvals and PASSED inspection results. The workmanship of the installation was high quality all the way and it worked right during the test without a hitch."

"I highly recommend CAP Electrical for all of your electrical needs! Not only do they do an outstanding job, but they are extremely friendly, customer service oriented, and honest. The day that Rod (President) came out to give me an estimate, I thought that I had a short in one of my kitchen light fixtures. Rod quickly pointed out that I was not using the right type of bulb in the fixture (non-dimmable bulb on a dimmable light). That display of honesty led to me hiring Rod and his guys for the rest of the work I needed done, and I'm very glad I did. They ended up installing recessed lights in my basement, a receptacle on my front porch, repairing switches in my main breaker panel, and fixed existing receptacles throughout my house. The electricians Rod sent were very personable and courteous. They worked very efficiently, and ensured that my satisfaction was their number one priority. As the electricians worked they informed me that some of the work that they did was not as involved as originally anticipated, which ultimately led to me saving money. Another display of honesty and customer service at its finest. In addition, CAP was very flexible when it came to scheduling a day to come out. If you're looking for a company that prioritizes customer service and is extremely honest then look no further than CAP electrical. They are very good people who work hard and do the right thing! I'm very pleased with the work that they did and I know you will be too."

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
