"Lightning damaged several of the electronics in our house. I scheduled for an electrician to come out today and Dave was here, on time. He is professional and friendly...and he like dogs! Dave quickly and efficiently diagnosed each problem and was able to repair some items and give us direction for non-electrical repairs, such as HVAC and plumbing. Next time we need an electrical service, I guarantee it will be Gunther’s Electric!"

Electrical questions, answered by experts

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

Amps describe the amount of energy that can flow through a circuit breaker. Every electrical device that’s attached to the breaker requires about 1.5 amps. While that equates to roughly 13 receptacles per 20 amps, using slightly fewer ensures that your circuit will always have enough energy for sudden power surges instead of tripping when one occurs. In general, 10 to 12 receptacles is recommended for a 20 amp circuit.

Hiring a professional for attic fan installation or replacement is highly recommended to ensure safety, proper ventilation, and effectiveness without damaging your roof. The type of professional needed can vary based on the fan type and project specifics.

  • HVAC Technicians: They understand airflow and ventilation principles, making them well-suited for the job.

  • Roofers: Experienced roofers are ideal for roof-mounted fans, as they can ensure a watertight installation.

  • Electricians: A licensed electrician is essential if new wiring is needed, or for replacing solar or electric attic fans to safely handle the electrical connections.

  • Carpenters: They may be needed to install gable vent fans or to ensure a new fan fits the existing structure correctly.

  • Handyperson: For a simple replacement of an old fan with no wiring or structural modifications, a handyperson might be an option.

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. 

If your plug feels hot to the touch, it’s likely a sign of an electrical issue that needs immediate attention. Check for signs of melting or discoloration around the plug, as well as any burning smells or smoke. If you notice any of these signs, immediately unplug any devices and do not use the outlet again until it’s been inspected by a qualified electrician.
