"Ron, our installer, was absolutely wonderful! He arrived on time, was pleasant, and efficient. Ron worked on New Year's Eve, was close to finishing his job, but could have stretched it into the next day. Rather than leaving us "in the dark," he worked until the job was completed that day. We appreciate all the hard work from Ron! We definitely recommend Reinhold for any of your electric needs!"

"Hired “Power Up” to refit our electrical panel and install an outside connecting plug to run a new portable electric generator. Jeff came out and spent time to evaluate and discuss our needs. He was consultative throughout the whole process. Lisa was responsible for arranging installation and paperwork and was very responsive to inquiries as well as reaching out to confirm things were moving forward. Justin was our installer and he knew his stuff. Very friendly and completed the work on time and as expected. Great experience working with “Power Up.”"

"Jim for Donhohues Lightning Rods installed the lightning rod system in my home. When the work was done I was very happy as their installer came as per promised time, and perform the work. Before giving them the work Jim completely sold me their work ethics, quality, and service. There was a minor issue and his team took complete ownership of this issue and talked to me in detail. They provide a very good explanation to satisfy me. I am a happy customer."

Electrical FAQs, answered by experts

Aluminum wiring can pose a significant fire risk because it tends to expand, contract, and overheat, leading to failing connections and splices. If your home has aluminum wiring, it doesn't always require a complete replacement, but you must take safety precautions. The first step is to hire a licensed electrician to conduct a thorough inspection. Based on their findings, you have several options:

  • Full Replacement: The safest but most expensive solution is to replace all aluminum wiring with copper.

  • Copper Pigtailing: A more budget-friendly option, suitable for certain homes, involves adding a short section of copper wire to the end of each aluminum wire at connection points.

  • Other Safety Upgrades: Your electrician may also recommend installing aluminum-compatible outlets and applying an anti-oxidant paste to connections to prevent corrosion.

Consulting a professional will help you determine the best course of action to ensure your home's wiring meets current safety standards.

Timers work by using an internal switch to turn power on or off to the cord plugged into it. Just the same way that a light switch turns lights on and off, the timer throws the switch at the programmed times.

No, outdoor outlets are not required to be on a separate circuit. However, you should always defer to local electrical codes when making decisions about how to install your new outlet. An experienced local electrician will be able to inform you of all codes and requirements in place at your home.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Yes, you can connect two extra outlets (or more) to one outlet if the total load on the circuit allows for it. If you have a 15-amp circuit, electrical code allows up to eight outlets or light switches. But if you’re dealing with outlets in the kitchen and bathroom, you may not be able to have as many. Kitchen and bathroom appliances often need higher amperage. You can also change a single outlet to a double outlet by cutting a larger hole in the drywall and replacing the outlet with a quad receptacle.
