Hi my name is Trevor Smith and I am a California state certified Electrician. I have over 15 years experience in Residential, Commercial and Industrial electrical work. I have been trained by the union and I am a member of IBEW in good standing and am looking to help you with all your electrical needs: Troubleshooting fans, cans, spas, grow rooms etc no job to small. Same day call back Same day service I am willing to work with you on the price and I will do work for trade. Contact today for more information!

"Beware, Trevor is extremely incompetent and a complete rip off. All we needed was a simple 240 panel swap First he gave us a price to start in 3 days and a price to start in 5 days for 6k more. This was on a formal written quotation. We chose 3 days because it was an emergency. He ended up ordering the wrong panel and by the time the replacement was delivered, we were at 7 days. He still charged us the additional 6k. Next, the 2nd panel had a connections approximately 12" further than the original panel. Without quoting or even indicating that we would have to pay for this he replaced a few feet of 100 amp wire and added $4200 to the invoice! The best one is the $1500 he added to "determine which phase the stinger leg was was supposed to be on." He checked alright by process of elimination. He guessed wrong and caught my office on fire! What kind of person has the nerve to charge for that after setting your building on fire. We ended up withholding payment on the last 2 charges to get clarity from him about their legitimacy. He showed up at our business very hostile and started screaming about giving him his money and what he would do if I didn't. He had already been paid the 19k on the original estimate. He would not listen to anything or leave and ultimately I had to threaten to call the cops to get him out of there. This guy is a scam artist and a safety hazard. Save your wallet and your building and hire someone else."

Integrity and quality! Profit and speed is the priority of most companies today, many do not care about quality, safety, reliability! When it comes to VOLTEX, you will be impressed by our approach to business. Yes we will do the job 1 day longer, 1 dollar more expensive, but we will give an extended warranty on their work and many years of trouble-free work that will ultimately save your budget, time, and safety.

"Voltyx went great. Both techs (Erik and Vladimir) were professional and hard working. The dispatcher/project manager (Roman) was courteous and very easy to work with."

Electrical questions, answered by experts

The purpose of pigtail wiring is to connect multiple wires to a single terminal on a device. Pigtailing involves splicing a short length of wire, called a pigtail, into the multiple wires that need to be connected. The pigtail wire is then connected to the single terminal on the device, allowing all of the wires to be connected at once. This practice helps to simplify the wiring process, reduce clutter, and ensure a secure and reliable electrical connection.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

If you’re someone who likes to tinker around the house and make DIY repairs, a multimeter or voltmeter can be a great tool to have around, especially if you’re comfortable with electrical repairs. That said, if working with electricity feels out of your depth, you don’t need to invest in a multimeter. Reach out to an electrical pro for any electrical work you need done if any part of you is hesitant about a project.

Using too many Christmas lights can cause your circuit board to overload which can put your tree at risk of catching fire and potentially damage your home’s electrical grid. 

Wiring or installing a light the wrong way can lead to potentially dangerous scenarios, including shock and even electrical fires. If you’re the least bit uncertain whether you’ve wired something correctly, the best and safest approach is to call in a professional electrician to handle the installation for you.
