"Outstanding, Marty helped us troubleshoot why we lost electricity in two rooms. He was always upfront with the potential causes and gave us options to correct. This is our second time hiring Marty and definitely won't be the last. Professional, knowledgeable and reasonably priced."

Customers say: True professional

"Scott is excellent to work with in all aspects of electrical. I am a general contractor and Moses Electric has done all my electrical for the past 12yrs. I look to no one else. From the non working outlet or switch, to service upgrades, underground work, data, fire alarm panels, low voltage, new construction, remodeling, troubleshooting, all the way to 3 phase industrial and commercial work. Scott has been along side me for all aspects of the electrical work and never skipped a beat. I have full confidence to refer Moses Electric to my own clients, friends and family. Knowing when I pass his name along it will not come back to me with a negative effect. Always happy clients every time, in addition to being clean in all aspects of presentation and workmanship. I am not biased because I am in the trades. We rely on referrals and relationships to provide our living so there is no benefit to saying what isn't true. I highly recommend Scott and Moses Electric for any of your electrical needs. He makes the process easy and seamless."

"Arete’s team was incredibly professional and efficient. They completed my HVAC job in a timely manner and beat competitor’s pricing. Their team was very respectful of my home and even wiped the floor after each day’s work. Every member of the team was kind and respectful. Will certainly work with them again in the future for any of my HVAC/electrical needs."

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

The average lifespan of a home electrical system is anywhere from 30 to 70 years or more, depending on the type of system you have. Modern electrical wiring, like aluminum or copper, can last 50 to 70 years while older types may need to be replaced sooner. Additionally, circuit breakers tend to last anywhere from 30 to 40 years, while electrical outlets need to be replaced every 10 to 25 years. 

The copper wire used in knob and tube wiring systems can last up to 100 years. However, it’s considered a dangerous and outdated wiring method because the cloth, fabric, or rubber insulation sheathing can become brittle and fall apart. Knob and tube wiring systems should be inspected if you’re considering buying a home with this type of wiring, or if you have problems with frequently tripping breakers, a sign that you may need to replace them.

Rewiring projects cost anywhere between $1,500 and $10,000 on average, depending on the complexity and the size of the rewiring. You can anticipate spending between $2 and $4 per square foot of wire, including labor and materials. Wire material ranges from $0.25 to $1.60 per linear foot.

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.
