"Pablo and crew did an awesome job. They added 3 dedicated lines to the kitchen, from the electric panel through the attic. Very professional and clean. Would hire them again for any electrical problem."

"Kevin did a fantastic job on our panel upgrade. He arrived on time and quickly got to whipping up a quote on the spot. He gave us several options that were all reasonable and made sense such as a basic level panel swap and a higher tier panel with lots of expandability including solar-ready. He also gave some additional add-on options such as grounding rods and stucco repair which was greatly appreciated although ultimately we did not use. Not once did Kevin try to pressure us into purchasing these additional add-ons which is greatly appreciated. Kevin is a respectful and does not get pushy. He arrived in a very professional truck with an additional electrician. Together they were able to get all the work done within one day with minimal disruption. I also really appreciate how clean the stucco breakout was as I have seen other electricians just take a sledgehammer and really leave the stucco in bad shape. I would definitely recommend Kevin and I will be reaching out to him for any future work."

"I recently hired Mazen from Smart Electrical Solutions for a multi-stage project at my home, and I couldn't be more impressed with the results. The project was complex: a full electrical panel upgrade, a complete layout of recessed lighting, and some tricky troubleshooting of older circuits that had been giving me trouble for years. Mazen handled the panel upgrade with incredible precision. The wiring is remarkably clean and organized, and he took the time to clearly label every single breaker—something my previous electrician overlooked."

"This past winter we came to terms that our home needed an expensive upgrade. Electrical panels. My husband and I shopped around, like most we wanted quality at a great price. Sergio was very upfront with us, as a busy working family thats very important. During our consultation visit he was very patient with all of our questions. Also gave us good ideas for future upgrades. Home improvement are typically stressful, so having a patient and understanding professional helps the process so much easier."

"Prime Electric Solutions informed me of the Charge-Ready program offered by SCE, which gave me a rebate of $4,200 for upgrading my electrical panel if I installed an electric vehicle charger at the property. They were efficient, communicative, and very friendly. I'm extremely happy with their service and I will use them again if needed in the future."

FAQs for electrical wiring or panel upgrade projects in Rancho Cucamonga, 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.
