"Excellent service. I needed to upgrade my electric panel, Ben did an excellent job very professional. Installing switches, circuit breaker panels, relays, and other electrical control and distribution equipment was the right call. I look at several electricians with reasonable prices and CA Electrical Group was definitely the right call. I will highly recommend CA Electrical Group to all my friends. What was important to me was his daily commitment to start and finish the job the dates we agreed on."

"Single Line Electric came to my house to view my need. 2 other companies I called wanted me to send a video of my home showing them my yard from the electrical box to my pool. They obviously didn't want the job. Nery came out and did a thorough assessment of my needs. His quote was reasonable and the project began soon after. I am very pleased with with Single Line Electric"

"I hired Aaron Murphy Electric to install a 240v EV charging outlet. Aaron was quick and concise, very easy and friendly to work with and very flexible with timing. Install went extremely smooth and quick, and the price was better than I was expecting. Very courteous and left the area more clean than when he arrived. I would definitely recommend him again, and will be calling for any other electrical work I need done."

"We hired proper power electric to update lighting and switches in our home. Forest and foster showed up on time. They were professional and in sync with each other. We added recessed lighting, fan ,and outdoor lights to our new home. Forest made suggestion to add another switch down the hallway to make it easier to turn off lights when going to the room. Both were knowledgeable, helpful and very friendly. They even helped my neighbor with their solar panel system. We had a great experience and will definitely hire again."

Electrical questions, answered by experts

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

You should install a 25-amp breaker for your outdoor electrical outlet. If your outlet is only for use in an outdoor kitchen area for standard appliances, then a 15- to 20-amp circuit breaker should work. However, you will need to install a GFCI receptacle or breaker to ensure that the breaker trips on contact with water.

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

Knob and tube wiring is old, and its casing is brittle. This means that it's possible to receive a dangerous electrical shock if you touch a live wire and essentially become an electrical pathway. Although the scenario is unlikely, touching any K&T wiring is simply not a good idea in any instance. Leave any wire handling to the professionals.

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.
