"I highly recommend First Class Electric. I called this morning and by 10 am Joey the technician was calling me confirming he was on his way. The operator who made the appointment was very friendly and helpful. The technician Joey was very knowledgeable and friendly. He is an asset to your company! He understood what needed to be done and explained his plan. He made sure I was satisfied and answered every question. I will definitely use this company again but I want Joey to be the technician. Thank You!!!"

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

Electrical questions, answered by experts

Running conduits through an exterior wall is an effective method for powering outdoor spaces. From gardens to sheds to garages and more, it can be important to have electricity outdoors. Using conduit, which safely covers wires outdoors, is an easy way to get power where homeowners need it.

You shouldn’t try to touch the electric fence, as it will shock you. Typically, the shock is low enough to be uncomfortable to humans or animals that come into contact with the fence. But an electric fence with high voltage, or a faulty fence, could shock you and cause serious injuries when touched.

Yes, if something sparks when you plug it in or turn it on, it's important to unplug it immediately. A spark from an electrical appliance or device could indicate a short circuit, damaged wiring, or other electrical problems that could cause electrical fires or electrical shock. By unplugging the appliance, you can reduce the risk of electrical hazards and prevent damage to the device itself. It's important to avoid using the appliance until it has been inspected and repaired by a licensed professional to ensure that it’s safe to use.

It can be safe to buy or live in a house with knob and tube (K&T) wiring, but only if the system is in good condition, functional, and has been thoroughly inspected and approved by a licensed electrician. Never purchase a home with K&T wiring without getting a professional electrical inspection first.

Key considerations include:

  • Safety and Condition: An inspector will verify that the wiring is safe and has not deteriorated. Over time, the insulation can wear away, leaving exposed wires that pose a significant fire or shock hazard.

  • System Capacity: The electrical service should be at least 60 amps. However, even at this capacity, K&T systems often struggle to handle the demands of modern appliances and electronics.

  • Lack of Grounding: Knob and tube wiring is an ungrounded system, which is a safety concern for many modern devices.

  • Ongoing Maintenance: If you live in a home with K&T wiring, it's recommended to have it inspected by an electrician every one to two years to ensure it remains in safe working order.

Ultimately, any inspection or modification of a knob and tube system should always be performed by a certified professional.

The common, marked as COM or C, is one of the terminals found in your light switch. It houses the live wire that supplies the input voltage. The other terminals, marked as L1 or L2, are the outputs to the light fixtures. Depending on if you have a one-way or two-way switch, you’ll either have just an L1 terminal or both an L1 and L2 terminal.
