"From my perspective things worked out super. Based on input from several electrical contractors addressing various shorts and tripped circuits since adding solar I was advised that my service box was too small and needed upgrading. Fortunately, I called JVEC for an upgrade estimate. The owner came out personally and diagnosed my problem as wiring not secured appropriately to breakers after explaining how that impacted my system. After securing my panel we parted with a hand shake, shared contact info and a promised consideration for any future electrical concerns. As for tripped breakers, so far so good…"

"The whole process, from estimate to follow-up service, was superb. There was an issue with the installed timer. A simple request and the replacement was scheduled for replacement within a week at no charge. A request for an upgrade was also done quickly for a small charge. I highly recommend Martin!"

"MJ services was a professional and reliable business. They upgraded my electrical panel to 200. He obtained permits from the city and everything easily passed during inspection. His prices were reasonable and he even installed my EV Tesla charger. Would recommend him to anyone."

"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!"

FAQs for electrical wiring or panel upgrade projects in La Puente, 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.
