Prince George's County Department of Permitting, Inspections, and Enforcement requires a permit for any service upgrade or panel replacement. As a Maryland State Board of Electricians licensee, I handle that filing. The county enforces the NEC 2023, which mandates AFCI and GFCI protection in many more areas than older codes. Proper permitting ensures the work is inspected for safety and that your system meets all current standards for insurance and resale.

It's likely a combination of factors. Pepco's grid experiences moderate surge risk from our seasonal thunderstorms. While the utility manages large-scale faults, smaller voltage spikes can travel into your home. Older wiring and panels offer little protection for sensitive electronics. Installing a whole-house surge protector at your service entrance is the most effective defense for your smart home devices.

Yes, the rolling suburban landscape can impact grounding. Soil composition and moisture content vary with the terrain, affecting the resistance of your grounding electrode system. Rocky or overly dry soil near a foundation can lead to a poor ground connection. We test ground resistance during a service evaluation to ensure your system can safely dissipate fault currents, which is vital for surge protection and breaker operation.

Not safely. Federal Pacific panels have a known failure rate and are not compatible with modern safety requirements. Even if the panel were sound, a 100-amp service from 1973 lacks the capacity for a major new load like a Level 2 charger or heat pump. A full service upgrade to at least 200 amps is the necessary first step for safety and functionality.

Overhead service masts are standard here but have specific vulnerabilities. The mast itself can be damaged by falling branches or severe weather. More commonly, the connection point at the roof can degrade, allowing moisture infiltration into the service entrance cable. We inspect the mast's structural integrity, weatherhead seal, and the condition of the service cables during any major evaluation to prevent outages or water damage.

Summer AC peaks strain the grid, while winter lows near 18°F can bring ice loading on overhead lines. For brownouts, ensure your HVAC system is serviced and consider a hard-wired generator with a proper transfer switch for essential circuits. For surge protection, as mentioned, a whole-house unit is critical. These steps protect your home's infrastructure from external grid instability.

Your home's electrical system is now 53 years old. The original NM-B (Romex) wiring and 100-amp panel were designed for a different era, with far fewer high-draw appliances. Today's refrigerators, computers, and central air conditioning create a cumulative load that can overwhelm the capacity of that era's wiring, leading to voltage drop—which you experience as dimming lights.

For a burning smell, turn off the main breaker and call us immediately. From a dispatch point near Glassmanor Elementary School, we can use I-495 to reach most homes in the neighborhood within that 5-8 minute window. A burning odor often indicates overheating at a connection, which is a fire risk that requires urgent, professional diagnosis.
