"Great experience from start to finish. My wife and I needed to have 2 ceiling fans and light kits installed. The work was scheduled quickly and TFC Electrical Services was even able to do the job earlier than expected. Tom and Ralph arrived as scheduled, on time and we were given a fair price quote. They had to install electrical wiring and box in our bedroom ceiling prior to installing the fan and light. They took the time to protect our furniture and floors by covering everything with protective tarps. Additionally, the installed a fan and light kit in an adjacent staircase. The concern and respect that they showed for our home was admirable and appreciated. The installations were neat, clean and expertly completed. They completed all the work in about 3 hours. TFC Electrical Services should be a model for “ALL” other electrical contractors. Any future electrical work in my home will be offered to this company. Thank you Theresa, Tom and Ralph."

"As a Building & General Contractor myself Newgrange electric is one of my best electrical sub contractors. Eddie the owner is very hard working. Always reliable, extremely professional and maintains an office manager Nicole who knows what's going on, on all their projects so you always have someone to contact during business hours. Eddies crew is based of long time employees that are very knowledgeable in there work. Eddie will always get back to you even after business hours, which is not the norm for many vendors. We need more contractors like this. Joe Algeri, Orchard Builders & Construction & Skyline Plumbing & Heating."

"My home was destroyed by Sandy and needless to say had to be rewired including a new electrical panel. I also had a generator wiring done and all my lighting fixtures. He is very meticulous and clean. I highly recommend Ryan for any electrical needs."

Electrical questions, answered by experts

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

No, it is not safe to use an outlet that sparked. A spark from an outlet could indicate a short circuit, loose or frayed wiring, or other serious damage. Continuing to use an outlet that sparks can increase the risk of electrical shock, electrical fires, and other hazards. It's important to turn off the power to the outlet at the circuit breaker if possible and avoid using the outlet until a licensed electrician has inspected and repaired it.

It wouldn’t be abnormal to view all wiring as simply wiring, but wiring has different gauges and can handle different loads. When you’re wiring for 240V, you need wire that is rated at least 240V, but honestly it’s better to spend a little more and just buy 300V wiring. This ensures a margin of safety in case the wiring gets overloaded.

Yes, an AFCI (arc fault circuit interrupter) outlet also has line and load terminals, although it uses different technology than a GFCI and offers a different kind of protection. AFCIs monitor for internal arc faults, a type of wiring problem that can start an electrical fire.
