"My previous electrician had sadly done a terrible job performing my panel upgrade from 100a to 200a. Also, the permitting stages were not followed and I was unfortunately not compliant because of it. After shopping around for many electricians, I eventually met Mike and knew he was the guy that I was going to work with. Mike explained every detail one step at a time. My project was a large project since I was to not only rewire my 200amp panel, we had to fix grounding, water bonding, and also Trench 4 feet deep for SDGE to upgrade our line from 100a to 200a as well. This was a long and stressful process that became super easy because of the effort and work put in by Mike and his team. Mike was here for all of the permitting stages whenever the city or SDGE was here, so that he could answer all their questions and concerns directly. Mike will continue being my electrician from now on. I highly suggest MIke and his team for all of your electrician needs. They are very quick to answer phone calls, text messages, explain all processes and next steps. Super fortunate to have Mike on my home improvement team."

"Brian Kissel was very easy to work with from estimate to project completion. He handled the city permit, SCE inspections, stucco repair, and of course, installation of our new exterior circuit breaker panel. Highly recommend Kissel Electric."

"Joe's Electric returned my care within minutes of me contacting them. I had a technician in my home in 1.5 hrs. Who quickly identified and fixed the problem within 35-45 minutes. They saved me from losing a whole day of work and it was worth the cost vs loss I would have incurred."

"When we decided to get recessed lighting in our family room, we knew we would call Raymond and his team at Excellence Electric. They had done an amazing job completely replacing our old electrical panel a few years ago. As we expected, Raymond got back to us in a very timely manner, and he and his team started the work immediately thereafter. His team consists of very skilled technicians who can do it all. They even did the drywall repair. Once they did the job in our front room, it looked so incredible, we had them do the whole house. What a difference it has made! It was the single most amazing upgrade we could have made to our home. Many thanks to the fantastic team at Excellence. They were all professional, efficient, and so incredibly nice. The peace of mind we have knowing that we can rely on Excellence for all our electrical needs and issues is beyond measure."

"I got a few estimates to get more power out to my studio. Everyone quoted me about 4K to upgrade my panel and get dedicated line out to my studion. These guys were to only ones that looked for a better/more economical solution. I sent a pic of my panel and he remembered that I upgraded my kitchen a while back but noticed that my electric stove had it's own dedicated line. He asked me, did you convert to gas when you remodeled? I said yes and he said, great, we take the line that was dedicated to the stove and we use that. It saved me $1500 and it worked perfectly. I would absolutely hire again!"

"I had a car wall charger that wasn't working. I called Steve for help. Steve called me back to discuss my issue. Over the phone Steve told me several things to look for that might be causing the issue. After testing and inspecting the wiring based on his suggestions, I was able to locate and correct the problem. Steve helped me with this over two phone calls, and I was very impressed that he'd take the time to work with me. Thanks Steve!"

FAQs for electrical wiring or panel upgrade projects in Lake Forest, CA

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
