"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 ."

Electrical questions, answered by experts

You can move an electric meter outside if you currently have one inside your home. This is considered a larger move, so be prepared to pay on the upper end of $600 to $1,200. When hiring a professional electrician to move your electric meter, be sure to specify its current location and desired location, including pictures if possible.

While washers and dryers do not require a GFCI (ground fault circuit interrupter) outlet to function properly, electrical codes often mandate their use for safety. The National Electrical Code (NEC) requires GFCI protection for all outlets within six feet of a water source. This means a washer and dryer must be plugged into a GFCI outlet if they are installed in locations like a laundry room, utility room, garage, or basement. In other areas without a nearby water source, there is no specific requirement, but using a GFCI outlet is still recommended for extra peace of mind. It is always best to consult your local codes and regulations to ensure compliance and safety.

The copper wire used in knob and tube wiring systems can last up to 100 years. However, it’s considered a dangerous and outdated wiring method because the cloth, fabric, or rubber insulation sheathing can become brittle and fall apart. Knob and tube wiring systems should be inspected if you’re considering buying a home with this type of wiring, or if you have problems with frequently tripping breakers, a sign that you may need to replace them.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

The cost of fixing faulty wiring depends on the type of repair required. Replacing an electrical service line, for example, can cost up to $500. Rewiring an entire house will cost at least several thousand dollars. Replacing old wiring like knob and tube wiring will be even more expensive, but fortunately that kind of outdated wiring is fairly rare. Always get an estimate from a reliable electrician to learn the cost details.
