"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."

Electrical questions, answered by experts

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.

It’s a great idea to replace and update outlets, especially if an outlet stops working. New outlets work well with modern appliances and devices. Over time, outlets become old and worn—they can even become damaged, cracked, and burnt if the wiring is old and outdated. Old outlets and wiring can cause smoke, sparks, flickering lights, and an electrical fire.

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 number of outdoor outlets that can be on one circuit depends on the circuit's capacity and the electrical load of each outlet. Outdoor outlets should ideally be on a dedicated circuit that is not shared with other outlets, and each outlet should be rated for at least 15 amps. A circuit rated for at least 20 amps is recommended. It’s important to use GFCI protection for all outdoor outlets to prevent electrical shocks. Overall, it's crucial to avoid overloading the circuit and take necessary safety precautions.

Aluminum wiring can pose a fire risk as it can overheat, expand, and contract, leading to failing splices and loose connections. If your home has aluminum wiring, it requires careful maintenance and potential safety upgrades. The first step is to hire a licensed electrician to conduct a thorough inspection.

A complete replacement with copper wire is the safest option but can be very expensive and is not always necessary. Other safety measures and upgrades include:

  • Copper Pigtailing: A more budget-friendly option where a short section of copper wire is added to each end of the aluminum wire. This is only appropriate for certain homes.

  • Aluminum-Compatible Outlets: Installing outlets specifically designed for use with aluminum wiring.

  • Anti-Oxidant Paste: Applying this paste to connections to prevent oxidation.

Consulting with a qualified electrician is essential to assess the condition of your wiring and determine the most appropriate updates to meet current safety standards.
