Underground service laterals, common here, are generally more reliable against weather but can be complex to repair. Your meter and main service panel must be readily accessible for Pepco and emergency personnel. We often find panels placed in finished basements or behind obstructions, which violates code. Ensure a clear 3-foot workspace in front of the panel and that the meter outside is not blocked by landscaping. This access is crucial for safety and any future service work.

From our dispatch near the Capital Wheel, we can typically be on-site in The Haven within 5-8 minutes via I-495. A burning odor indicates active overheating, which is an immediate fire hazard. Your first action should be to shut off the main breaker at your service panel if it is safe to access. We will then perform emergency diagnostics to locate the fault, which is often a failing breaker connection or overheated wiring at an outlet.

Yes, they are. The moderate surge risk from our seasonal thunderstorms introduces dirty power and voltage spikes that can damage sensitive electronics in smart thermostats, TVs, and computers. Flickering lights often indicate a loose connection or an overloaded circuit, which compounds the problem. Installing a whole-house surge protector at your main panel is a critical first defense, safeguarding all downstream devices from transient surges coming from the utility lines.

A 46-year-old electrical system, even with NM-B Romex wiring, was not designed for today's simultaneous loads. Modern kitchens and home offices demand more dedicated circuits and a higher total capacity than a 1980 design anticipated. We often find overloaded shared circuits in these homes, which can cause nuisance tripping and create a fire risk from overheated conductors. An assessment of your panel's circuit layout and a potential service upgrade are prudent steps for safety and functionality.

It can. Flat, moist soil typical of our coastal plain provides good conductivity for grounding electrodes, which is beneficial. However, high water tables can accelerate corrosion on underground grounding rods and connections over time. We recommend periodic inspection of your grounding electrode system, especially for homes built in the 1980s, to ensure it maintains a low-resistance path to earth as required by code for safety and surge dissipation.

Summer AC peaks strain the grid and can cause brownouts, while winter ice can lead to prolonged outages. For brownouts, ensure your HVAC system is on a dedicated, properly sized circuit to prevent overloads. For storm preparedness, consider a professionally installed manual or automatic transfer switch and a generator. This allows you to safely back up essential circuits without backfeeding power onto Pepco's lines, which is illegal and deadly for utility workers.

No, it is not safe. Federal Pacific panels are a known fire hazard due to breakers that can fail to trip during an overload. Adding high-demand loads like an EV charger or heat pump to this unreliable system is extremely risky. Even if the panel were safe, a 150A service from 1980 often lacks the physical space and modern bus bar design to support these new circuits properly. The required solution is a full panel replacement with a modern, listed panel and AFCI/GFCI protection before any new load is installed.

All major electrical work in Prince George's County requires a permit from the Department of Permitting, Inspections and Enforcement and must follow the 2023 NEC. As a Maryland State Board licensed Master Electrician, I handle the entire permit process—application, scheduling inspections, and ensuring compliance. Skipping permits risks fines, voids insurance coverage, and can create unsafe installations that fail to protect your home and family. Proper documentation is part of a professional job.
