"Mike from Apollo electric did all of the electrical work for an addition to my first home. Mike is on the job each day and is a pleasure to work with. He is knowledgeable in all phases of electrical work, as well as in general construction. This was a huge help during the construction of my home addition, as he offered excellent suggestions to move the project along in an efficient manner. Mike’s work passed Montville Township inspections with flying colors. Mike has recently installed electrical upgrades to our pool, HVAC system, and lighting in our new home. All work has proceeded smoothly. I would recommend this company to anyone."

"Technician came and diagnosed the issues and stated he would need to open up the roof. Came back another day and discovered that the problem would not require opening the ceiling. Ran to home depot to get some supplies and came back and had lights in my 2nd, 3rd floor bathrooms, and hallway working again within a hour. All in all it wound up costing me a 1/3 of the qouted price. Very promopt, professional and kind and absolutely will use them for any electrical needs I have in the future. I believe my technicians name was Jean or Neil, i wish I remembered for sure because he was excellent."

"Second time using B-Tec electric and I think now they are my go to electrician. I used them previously to upgrade my panel to 200 Amp and this time to hook up my new electric water heater. Both tasks were completed perfectly and fairly priced. I highly recommend B-Tec electric!"

"Scott is very experienced and he knew what to do with an electrical problem that I had. Opposed to other electricians, Scott knew exactly what was wrong. He did a good job and I am especially impressed with his honesty. Scott didn't use scare tactics or try to talk me into other unneeded electrical work."

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

"Iâ ve been working with Henry for a few years now. He replaced and upgraded my electrical panel, installed lighting outside my home, and installed lights in my basement. He is really experienced and very easy to work with. Since I donâ t know much about the technicalities of the work, he took the time to explain to me what heâ s going to do, how and by when. He always goes above and beyond to meet the timelines he set at the onset of the project and the quality of his work is outstanding."

FAQs for electrical wiring or panel upgrade projects in Cedar Knolls, NJ

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.
