"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"

"Cawiamca Heating, Cooling, and Electrical was professional, knowledgeable and nice from the very first call. The owner Ron came out within a day to scope out the project and provide very reasonable quotes. From there, he quickly scheduled the install of the new Furnance and had his team out very quickly. His team worked diligently, were knowledgeable and very nice. They were efficient and clean during the install, leaving no debris leftover. I would highly recommend using this company as I know I will continue to going forward."

Electrical questions, answered by experts

Grounded electrical outlets are usually three-pronged. You can also look for a grounding clip in your outlet boxes or use a circuit tester. If you’re unsure, consult a suitably qualified electrician regarding your home's electrical safety.

Some portable cooktops are compatible with standard 120-volt outlets, but most induction (and electric) ranges and stoves need a dedicated 220- or 240-volt circuit and 40 to 50 amps to work. If you are replacing an old electric range with an induction one, you likely already have the proper outlet, but it’s worth checking with a local appliance installation company.

The most common type of electrical outlet is a 3-prong outlet, which has two flat blades (one is wider than the other) and a round grounding pin. Older homes typically have 2-prong outlets that aren’t as safe as more modern options and are generally not up to current electrical codes.  Other outlets you can find in your home include 20A, 125 volt varieties for larger appliances like refrigerators or washing machines. 

There are also GFCI outlets, which protect against electrical shock in wet areas, such as bathrooms and kitchens, and arc fault circuit interrupter (AFCI) outlets, which protect against electrical fires caused by arcing.

Knowing if and when your circuit breaker is failing or faulty can prevent costly damage. If you notice any of the following signs, call a local electrician to help. 

  • The breaker frequently trips

  • The breaker doesn't stay in the 'on' position or reset properly

  • You hear buzzing or humming noises coming from the breaker

  • There's discoloration around the breaker switch

  • There's a burning smell or visible signs of damage on the breaker

The color code for the common sprinkler wire is white, and then you can assign the remaining color codes to the rest of the wires for different sprinkler zones. For example, you could use red for the first zone, then blue for the second, and so on.

Color-coding helps you keep track of which wires go to specific zones so that you or a pro can address any issues or repairs quickly. Check your local electrical code for any requirements regarding sprinkler wire colors.
