"Tom and his team did an amazing job. They showed up on time, were very professional and cleaned up after each day. Their work was neat and they also installed quality hardware - which not may electricians do. I would highly recommend TFC Electric for anyone looking for a great job at a fair price. Will definitely use in the future."

"Mike Connelly of Shamrock Electric Co. Coordinated the installation of my whole house Generac generator with PSEG long island and my plumber. He connected the automatic transfer switch and fully tested the system upon completion of the install. He has it set to run a test for 10 minutes once a week. My wife and I are extremely happy with the unit and the professional set-up by Shamrock Electric Company ."

"They showed up promptly and did a great job. They were clean, neat and very professional. I would highly recommend them. They solved my electrical problem and John was great at explaining how he was going to fix it. Their prices are also very fair. Getting a good service person nowadays is becoming more difficult. They were really good. If you need a good electrician call them and speak with Darren."

Electrical FAQs, answered by experts

If you connect the wrong electrical wires together, it can lead to a very dangerous electrical shock. All wires should be matched with wires of the same color. It’s very important to consult an electrician if you’re unsure about how to wire your fixture.

Unless you’re a licensed electrician with extensive experience in upgrading electric panels, you must hire a professional for any electrical work. A licensed electrician will make sure your breaker is upgraded safely and in compliance with local codes. Your pro will also take care of any permits and inspections that are needed.

Check the matching breaker in your panel, since the number is printed on the switch. You can also tell them apart by sight. A 15-amp outlet has two straight vertical slots, while a 20-amp outlet has one vertical slot and one sideways T-slot.

Yes, it's possible to have electrical receptacles and overhead lights on the same circuit. The reason is that lights typically use much less power than large appliances, so combining them won't overload your circuit. By doing this, you can distribute the power consumption throughout the breakers in your panel more efficiently, which can be helpful if you have a lot of different electrical devices in your home.

The color code for the common sprinkler wire is white, and then you can assign the remaining color codes to the rest of the wires for different sprinkler zones. For example, you could use red for the first zone, then blue for the second, and so on.

Color-coding helps you keep track of which wires go to specific zones so that you or a pro can address any issues or repairs quickly. Check your local electrical code for any requirements regarding sprinkler wire colors.
