"They contacted us in a prompt timeframe, confirmed the appt, showed up and did the job all in one day for a reasonable fee. The new fan/ light for our bathroom looks great and they cleaned up after their work. They were pleasant and wore their masks the whole time. We will definitely call Bob Daniels Electric when we have another electrical project."

Electrical questions, answered by experts

Unless you have prior electrical experience, it’s best to hire a professional to install your new thermostat for you. Improper installation can damage wiring, lead to a blown fuse, and more.

Often, you can add extra breakers to an electrical panel. A new breaker can help with new appliance needs, and it’s a common solution when finishing an attic or basement. However, adding extra breakers can’t bring in more amps to your house, so you still need enough amp service to power everything in total. 

A 3-prong, 15-amp, 120-volt outlet is standard in the U.S. These have two vertical slots and a U-shaped grounding hole, which suits most home electronics, from televisions to microwaves. Three-pronged outlets are safer than 2-pronged ones, as the third wire, known as the grounding wire, helps prevent shocks and electrical fires.

Aluminum wiring can pose a significant fire risk because it tends to expand, contract, and overheat, leading to failing connections and splices. If your home has aluminum wiring, it doesn't always require a complete replacement, but you must take safety precautions. The first step is to hire a licensed electrician to conduct a thorough inspection. Based on their findings, you have several options:

  • Full Replacement: The safest but most expensive solution is to replace all aluminum wiring with copper.

  • Copper Pigtailing: A more budget-friendly option, suitable for certain homes, involves adding a short section of copper wire to the end of each aluminum wire at connection points.

  • Other Safety Upgrades: Your electrician may also recommend installing aluminum-compatible outlets and applying an anti-oxidant paste to connections to prevent corrosion.

Consulting a professional will help you determine the best course of action to ensure your home's wiring meets current safety standards.

If a 3-way switch is wired incorrectly, this can cause several issues. The most common problem is that the switches will not function properly: Either both switches won’t work, or only one will. Another issue is that one switch will trigger a short circuit, tripping the circuit breaker.
