Installing new high-capacity loads on a Federal Pacific panel is not recommended. These panels have a known failure rate and are not listed for new installations. Before adding a 240V EV charger or heat pump, the panel must be replaced with a modern, UL-listed unit. A 150A service may also be at its limit; a load calculation will determine if an upgrade to 200A is needed to safely support the new circuits without overloading the system.

Preparation focuses on backup power and surge protection. For winter ice storms that can knock out Pepco service, a permanently installed standby generator with an automatic transfer switch is the gold standard. For summer brownouts—momentary low voltage that strains AC compressors and motors—a whole-house surge protector is critical. It guards against the damaging surges that often occur when utility power flickers back on. Ensuring your panel and grounding system are in good health is the first step for either solution.

A 37-year-old electrical system, like yours, often struggles with modern loads. Original NM-B Romex wiring is generally safe if undamaged, but 1989-era circuits were designed for fewer high-demand appliances. Dimming lights typically point to voltage drop, which can be caused by overloaded circuits or undersized conductors struggling to power today's HVAC systems and kitchen electronics. We can perform a load calculation to see if your 150A service needs an upgrade or if dedicated circuits should be added.

Underground service laterals, common in Mitchellville subdivisions, are generally more reliable than overhead lines. However, they add a step for upgrades. If your 150A service needs increasing to 200A, Pepco must often replace the underground cable from the transformer to your meter. We coordinate that utility side work with the county permit and handle everything on your side of the meter—new meter base, mast, and main panel—ensuring a seamless upgrade that meets all current 2020 NEC requirements for your home.

A burning odor from the panel is an emergency requiring immediate dispatch. From our staging near the Lake Arbor Community Center, we can typically be at your door in Mitchellville within 8-12 minutes via US-301. Do not attempt to reset any breakers. Our priority is to safely de-energize the affected area, identify the source of overheating—often a loose connection or failing breaker—and make a secure, temporary repair to restore essential power until a permanent fix is scheduled.

Flickering during Pepco thunderstorms is usually due to grid disturbances from lightning strikes or downed lines. Our area's moderate surge risk means these voltage fluctuations can reach your home's wiring. While utility-side issues are common, internal problems like a loose neutral connection can also cause flickering. For protection, a whole-house surge protector installed at your main panel is the most effective defense, safeguarding sensitive electronics from both external surges and internal wiring faults.

Yes, terrain can impact grounding effectiveness. The rolling, often rocky suburban soil in our area can have high resistance, making it harder to establish a solid earth connection for your grounding electrode system. A proper ground is non-negotiable for safety and surge dissipation. We test ground rod resistance and may need to drive additional rods or use a ground plate to achieve the low-resistance path required by the NEC. This is especially important for whole-house surge protectors to function correctly.

A panel replacement always requires a permit from the Prince George's County Department of Permitting, Inspections and Enforcement. As a Maryland-licensed master electrician, I pull the permit, which involves submitting the load calculation and equipment specs. The work must comply with the 2020 NEC, and a county inspector will verify the installation, including proper grounding and AFCI protection where required. Handling this red tape is part of our service; you get a certified, legal installation without the hassle.
