Is your home experiencing flickering lights, tripped breakers, or struggling to support modern appliances? These could be signs that your service panel is outdated and needs an upgrade. At David Williams Electric, we specialize in safe, code-compliant, and high-capacity service panel upgrades for residential and light commercial properties throughout Maryland.
Don’t let an aging electrical system put your property or family at risk. With over 20 years of hands-on experience, our licensed electricians ensure your upgrade is done right—the first time.
Your electrical service panel—also called a breaker box or load center—is the heart of your home’s power system. It distributes electricity from your utility company to the various circuits in your home.
However, panels installed more than 25–30 years ago weren’t designed to handle the electrical demands of today’s technology-driven homes.
Upgrading ensures safer electricity distribution, improves your home’s value, and gives you peace of mind.
Upgrading from a 100-amp panel to a 200-amp panel gives your home the power it needs to support today’s appliances and future growth.
Home inspectors and buyers often flag outdated panels. A modern service panel is a strong selling point for resale.
Newer panels meet current NEC (National Electrical Code) standards and reduce the risk of electrical fires caused by overloaded or faulty circuits.
A panel upgrade prepares your home for solar power integration, home automation, and EV charger installations.
Reduce the risk of tripped breakers and protect sensitive electronics from voltage drops or surges.
