"Raul is awesome! Couldn't have asked for a better electrician to work on my projects. He is an expert and has a great work ethic. He installed a chandelier, light switch, and neon sign above my fireplace. He also rerouted wires in my guest bathroom and installed a vanity light. He also added three outlets in the house. Great work all around. I would definitely recommend him for anyone that needs electric work done."

"C&S was very professional and yet still very polite and personable. That makes perfect sense since the owner and founder is a US Armed Forces vet. Seth and Jeremiah made quick work of my flood light installation when they arrived. Earlier, Seth had recommended a supplier where I could select the fixture that worked best for my application. The labor cost was very fair and I was pleased to pay the "contractor price" for my fixture. Overall, I had a VERY GOOD experience with C&S and I would recommend this company highly."

Generator Install questions, answered by experts

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.
