Electrical Panel and Junction Box Installation & Repair

A commercial electrical sub-panel, which is connected to your company’s main panel, offers more power and the option to add additional circuits. However, it is not always an easy task. Many factors need to be taken into consideration to provide a safe and proper electrical panel installation. Let us recommend the best option for your business needs.

Properly sized electrical panels and robust junction boxes are the critical backbones of any commercial facility.

We tackle upgrades, maintenance, and emergency fixes on these components so businesses can operate smoothly.

For panel installation and repair, our electricians first size new panels based on calculated amp needs for planned lighting, devices, and heavy equipment throughout your space.

We install top name panels safely while ensuring balanced multi-wire branch circuits, high-integrity ground connections, neatly organized breakers, plus excess room for inevitable growth.

We especially prevent component damage by rejecting poor supply power quality.

This proactive approach prevents nuisance outages or worse yet, fire hazards which threaten business continuity and reputations.

On the repair front, we troubleshoot faulty breakers and overheated bus bars, replace damaged wiring insulation promptly and solve overload faults however complex to restore system stability.

Likewise for commercial junction boxes, we install durable, correctly sized metal boxes at each cable splice/device/fixture point.

Rigid mounting plus strict limit of wire bend radii within boxes ensures continuous cable protection.

When fixings loosen causing intermittent, dangerous connections to lighting or controls, we thoroughly inspect source junctions, reestablish clean joins, then stabilize boxes against additional movement per industry best practice.

For high moisture areas, we swap metal clad waterproof boxes having flexible-entry grommets for securing cables evenly and safely.

Taking a proactive yet urgent approach to junction box issues minimizes further wire insulation breakdowns and premature failures which become exponentially more costly long term.

With both electrical panels and junction boxes, having our licensed technicians on staff allows promptly identifying degrading parts far before outages even occur.

We take pride providing essential preventative maintenance plus urgent repair services that keep Orange County buildings bright, comfortable and running every day and night.

Green Lighting Installation & Repair

Want to brighten up an area of your office or cut down on your energy bill? Using old, inefficient lighting fixtures can cause your power bill to increase significantly. An ordinary bulb produces only 5% to 10% of the energy it consumes as light. The rest is then converted to heat.

Our skilled electricians can design a lighting system to suit your needs, maximize your savings, and contribute to resource conservation all at the same time.

Our comprehensive warranty on selected fixtures and bulbs back up our superior work. Lighting repair services are also provided by Fullerton Electrician! 

When it comes to lighting your commercial spaces sustainably, we’ve got you covered. As your friendly electricians, we stay on top of all the latest in green lighting technology—from smart LED fixtures to advanced controls. We’ll walk you through the options to find the best fit, whether you’re building new or improving what’s there.

For new construction and remodeling projects, we strongly recommend building a LED lighting backbone right from the start. The benefits are huge: LEDs consume way less electricity and last years longer than outdated lighting—we’re talking decades with no bulb changes. Whether selecting strips to backlight display shelves, adjustable recessed cans for galleries, or durable exterior illumination that won’t attract bugs, LEDs just make sense. We’ll take care of the entire planning and installation process from circuit sizing to casting beautiful, uniform light wherever you need it.

Another green choice is integrating advanced lighting controls like occupancy sensors, scheduled dimming, and daylight harvesting. These smart systems turn lights on/off or automatically adjust output based on conditions—saving tons of unused power. We can network these technologies on a building-wide platform, allowing you to configure scenes from your computer as usage needs change.

On the maintenance side, we offer full-scale audits of existing lighting using tools that analyze spectrum, calculate usage stats, and identify replacement opportunities. Outdated T12 fluorescents are particularly problematic—they hog energy even when dimmed, containing toxic mercury too. Swapping old fixtures for LED equivalents pays off fast. We recycle the hazardous materials properly and qualify any utility rebates to offset costs as well.

At the end of the day, green lighting saves money while reducing environmental impact. Call us to discuss the possibilities for your commercial property whether small upgrades or a whole new modern system. We’ll tailor options to meet sustainability goals and the bottom line.

With everything mounted, our technicians thoroughly torque connections to exact tolerances and test protection relays end-to-end before inspection. This ensures every business function stays up and running.

On the transformer side for newbuilds, we analyze and order the perfect units to match utility service voltage with that required by lighting, HVAC and process equipment. While general contractors prepare pads, we line up crane vehicles for gentle placement at each building’s service entrance the moment transformers arrive. Adjusting inputs/outputs to balance phase loads along with grounding for public and gear safety all gets handled professionally start to finish.

When it comes to emergency switchgear/transformer repairs, we have the skill to troubleshoot root causes plus qualified staff to rebuild or source reconditioned replacements.

It was in 1999 when Fullerton Electrician was established. In 2009, Carl and Barbara Jackson purchased the business. It was then improved by adding electrical contracting services, new construction, remodeling, and sign installation and repair.

 

Carl has worked in the electrical industry for over 20 years. He began working at an electrical firm in New York City while going to evening classes for an apprenticeship.

 

Carl worked as a transit electrician, helping to upgrade and renovate the MTA subway stations throughout different boroughs, following graduation from apprenticeship school.

 

Carl was able to earn his master electrician license after working as an electrician for many years in both New York City and New Jersey. Wanting to move to the West Coast, Carl purchased Fullerton Electric Pros with his wife, Barbara.

 

Carl is an expert in all facets of the industry. He began as an apprentice about 20 years ago and rose through the ranks, taking over day-to-day management in 2005 and obtaining his master electrician’s license in the process.
