"I recently hired Spartan Electric to perform electrical work at my home, and I would like to share my experience. From the outset, Spartan Electric was prompt in responding to my inquiry. They scheduled an appointment quickly, which I appreciated given the urgency of my electrical issues. Upon arrival, Spartan Electric was punctual and exhibited professionalism, introducing themselves and explaining the work they would be performing. During the assessment of the issues, Spartan Electric took the time to explain the problems I was facing with my electrical system, providing clear insights into what needed to be done. This transparency helped me understand the situation better and made me feel more at ease about the process. The work itself was executed efficiently and to a high standard. They demonstrated a strong knowledge of electrical systems, and I noticed their attention to detail throughout the project."

Electrical FAQs, answered by experts

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

You can identify the amperage and voltage of most outlets by their slot shape and prong count. Buttons, switches, and USB ports also give it away. Look for printed labels like "TR" or "GFCI," and compare your outlet to the labeled images above.

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.

In general, 200 amps is enough for a house with a square footage of up to 1,800, or the average three-bedroom home. A 200-amp service allows your home to warm and cool itself while running multiple appliances at once. It's a good option for homes that have been extended, or after adding new appliances. 200-amp service is the current standard for homes, so in most cases, it will work for you.
