"Colin helped us out with running electricity to our detached garage, and installing a level 2 charger for our cars. His work was excellent and efficient. He was communicative before, during, and after the project, and he was on time each day. His initial bid was very competitive, and we're super glad that we chose Colin to work with. We're looking forward to our next project with him."

"Tom was friendly, knowledgeable, and did quality work for a reasonable price. He took a messy junction box full of unlabeled wires and stray voltage and cleaned it up and installed a ceiling fan in 90 minutes. I plan to hire him for all my electrical needs for now on."

Electrical questions, answered by experts

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.

You can tell if a breaker is GFCI by looking for a red or yellow test and reset button that you can press in and out. You’ll know if an outlet is GFCI if the red reset button is located in between the two pronged sections.

For most applications, you won’t need a neutral for 240V. There are certain codes and regulations that differ between areas so just because you technically may not need one in order for the device to function properly, it may still be a local requirement. Professionals in your area know the requirements, which is just another reason to hire one instead of taking on a project that is frankly not very DIY-friendly.

While not always necessary, wiring your circuit breaker in a certain way can ease both the installation process and use afterward. For starters, you’ll need to install the electrical panel so that the main service knockout aligns with the cable conduit. If they aren’t aligned, you may not have sufficient working space to finish running the wires. Using cable trays, on the other hand, gives you a bit more freedom to and flexibility in where and which direction you install the wires. At the end of the day, the power flow will be the same whether the cords run up or down.

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.
