With a Federal Pacific panel, which is a known safety hazard due to its failure to trip, the answer is no. That panel must be replaced before any major upgrade. Even after replacement, a 100A service from 1969 is typically insufficient for the continuous load of a Level 2 charger or heat pump. A service upgrade to 200A is the necessary first step to safely support these modern high-capacity systems.

Preparation focuses on backup power and surge protection. For winter lows near 15°F, a properly installed generator with a transfer switch can keep heat and essential circuits running if ice knocks out overhead lines. During summer AC peaks, a whole-house surge protector safeguards against voltage spikes from grid brownouts. Ensuring your service mast and connections are secure is also key before storm season.

Your home's electrical system is 57 years old. Original NM-B Romex wiring from 1969 was sized for a different era of appliances. Today's high-draw devices like air conditioners and microwaves can overload those circuits, causing voltage drop you see as dimming lights. This is a common capacity issue for Colesville Heights homes, signaling that your 100A service panel may no longer meet the demands of modern family life.

While Pepco manages the grid, the frequent seasonal thunderstorms in our area create moderate surge risk. Grid fluctuations can cause flickering, but your home's internal wiring and lack of proper surge protection are likely amplifying the problem. Sensitive electronics need defense at the point of entry. We recommend installing a whole-house surge protector at your main panel to absorb those spikes before they reach your devices.

Overhead mast service is common here. You should visually inspect the mast head and the cable (service drop) leading to it for weathering, animal damage, or loose connections, especially after storms. The mast itself must be securely anchored; a leaning mast is a serious hazard. Also, ensure tree limbs are kept well clear of the drop lines. Any work on the mast or service entrance cables requires a permit from the utility and the county.

Absolutely. The heavy tree canopy common in this area directly impacts electrical health. Branches contacting overhead service lines can cause intermittent faults, flickering, and even momentary outages. Furthermore, tree root systems in our soil can disrupt the path of your home's grounding electrode system, compromising its ability to safely divert fault currents. Regular tree trimming and a ground resistance check are wise precautions.

For an immediate safety hazard like that, we treat it as a priority dispatch. From our starting point near the Colesville Shopping Center, we can be on US-29 and at your location in Colesville Heights within 5 to 8 minutes. Our first action will be to safely disconnect power at the meter and assess the source of the burning odor, which often points to a failing breaker or overheated bus bar.

All panel upgrades in Montgomery County require a permit from the Department of Permitting Services and a final inspection. The work must comply with the 2023 National Electrical Code, which includes updated rules for AFCI protection and grounding. As a Maryland State Board licensed Master Electrician, I handle the entire permit process, ensuring the installation meets all current safety standards and passes inspection, so you don't have to navigate the red tape.
