Preparing for winter ice and summer peak demand involves two key strategies. First, ensure your service mast and overhead connections are secure; ice accumulation can pull lines down. For brownouts, consider a hardwired automatic transfer switch and generator to maintain critical circuits like heat or refrigeration. Low voltage during a brownout can also damage compressor motors in AC units and refrigerators, so surge protection remains important year-round.

Your home's electrical system is likely about 59 years old, built around 1967 with original cloth-jacketed copper wiring. This wiring was adequate for 1960s appliance loads, but lacks the capacity for modern central air, multiple refrigerators, and large-screen electronics that can easily overload a 100-amp panel. The voltage drop you see as dimming lights is a clear sign the system is operating at its limit, which can cause overheating and accelerated wear on connections throughout the house.

For a burning smell or loss of power, we treat it as a priority dispatch. From the Fairmount Heights Municipal Center area, we can typically be en route via I-495 within minutes for a 10-15 minute arrival. Your first action should be to shut off the main breaker if it's safe to access the panel, then call. This prevents potential arc damage while we are on the way to diagnose the fault.

A home from 1967 with a 100-amp panel faces significant challenges supporting a Level 2 EV charger or a heat pump. More critically, many homes in this era were equipped with Federal Pacific panels, which are a known fire hazard due to breakers that can fail to trip during an overload. A full service upgrade to a modern 200-amp panel with AFCI protection is not just recommended for capacity; it's a critical safety upgrade before adding any major new load.

Overhead service, common in Fairmount Heights, requires attention to the masthead where the utility lines connect to your home. Look for rust, sagging, or visible damage to the conduit. Ensure tree branches are trimmed well back from the service drop lines. The point where the overhead wires enter your meter is a frequent failure spot during high winds or ice storms, as the constant movement can loosen connections inside the weatherhead.

The rolling suburban hills in our area can impact grounding system effectiveness. Rocky or variable soil conditions make it difficult to achieve a low-resistance connection to earth, which is essential for safety. We often need to drive supplemental grounding electrodes or use chemical treatments to ensure the grounding electrode system meets NEC 2023 requirements, especially for older homes where the original ground rod may be compromised.

Replacing a panel requires a permit from the Prince George's County Department of Permitting, Inspections and Enforcement. As a Maryland State Board of Master Electricians licensee, I handle the application, ensure the installation meets all NEC 2023 code requirements for AFCI protection and working clearances, and schedule the required inspections. This process ensures the upgrade is documented for safety and future home sales, and that it integrates correctly with Pepco's meter and service.

While Pepco manages the grid, seasonal thunderstorms in our area create moderate surge risk that older electrical systems aren't designed to handle. These micro-surges can easily damage sensitive circuit boards in modern electronics. Installing a whole-house surge protector at your main panel is the most effective defense, as it intercepts surges from both utility lines and lightning-induced spikes before they enter your home's wiring.
