"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."

"We needed a NEMA 14-50 EV charger installed outdoors for an electric car, and got 3 quotes from Angie's List. Based on the 3 bids, it seemed certain we'd need a subpanel breaker box installed as our main breaker box was full and there were no empty slots to assign to the EV charger. However, only Tommy from Fairway offered up a potential solution within the existing breaker box, if they were able to source a hard to find quad breaker. It seemed unlikely, but would save a lot of hours (new box install / wiring under the house) and money. Sure enough, he source the part and made it happen. On top of that, they were professional and easy to work with. Highly recommend!"

"Glen, Enrique and Joseph did an amazing work rewiring our house. We started out just wanting to change the old panel and sub panel to a single panel for the whole house outside and fix a few outlets that went out to a complete rewire. Glen pointed out several problems with the wiring and how to fix it. Enrique and Joseph came in and worked through the house beginning with the garage and working through the kitchen. The work was done through patches instead of tearing the walls out. Rosa and Nicole were very helpful in the office with payments and permits. Enrique did the walk through with the inspector to ensure we passed inspection. The overall experience was excellent. I highly recommend Safe-Way Electric for any and all residential electrical needs. I now feel very safe in our home. Thank you for everything! Desiree and Scott Barrett"

"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."

"I called them about an electrical panel upgrade and they responded immediately. They looked at some pictures and heard our situation, did their calculations, and it turns out that we didn't need an electrical panel upgrade. Other companies might have done the calculations but gone along with us thinking we needed work done to get some business, but these guys were honest and upfront and ended up saving us a good amount of money."

FAQs for electrical wiring or panel upgrade projects in Walnut, CA

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
