Yes, a permit from the Conshohocken Borough Building & Code Enforcement office is legally required for a panel replacement or service upgrade. This ensures the work is inspected for safety and compliance. All electrical work must adhere to the current NEC 2023 code, which includes updated requirements for AFCI and GFCI protection. As a Pennsylvania-licensed master electrician, handling this permit and inspection process is a standard part of the job, ensuring your installation meets all Department of Labor and Industry standards.

Preparation focuses on safety and maintaining critical systems. For winter, ensure your heating system's electrical components are serviced and consider a hardwired backup generator with a proper transfer switch—never use a portable generator indoors or through a window. For summer brownouts, which strain an already overtaxed 100A system, installing AFCI breakers can help prevent fires from overheated wiring. A service upgrade provides the necessary capacity headroom to handle peak AC demand more reliably.

While PECO manages the grid, final surge protection is your responsibility. Conshohocken's moderate surge risk from seasonal thunderstorms means transient voltage spikes travel along utility lines and into your home's wiring. A basic power strip offers little protection. Installing a whole-house surge protector at your main service panel is the most effective defense, as it shunts damaging surges to ground before they can reach and degrade sensitive electronics like smart home hubs and computers.

Overhead service, common in Conshohocken, is more exposed to environmental factors like falling branches, ice, and wind, which can cause momentary outages. The mast where the service cable enters your home is a critical point; it must be properly secured and sealed to prevent water infiltration, which leads to corrosion inside your panel. While reliability is influenced by exposure, the greater concern for older homes is often the capacity and condition of the wiring and panel inside, which is independent of the overhead versus underground feed.

With your current 100A service and a panel from 1958, a safe installation is unlikely. A Level 2 EV charger alone can require a 40-50A dedicated circuit, and a heat pump adds another significant load. More critically, many homes of that era in this area were equipped with Federal Pacific panels, which are a known fire hazard and must be replaced before adding any major load. A full service upgrade to 200A is the standard, code-compliant path to support these modern systems.

The hilly river valley terrain can contribute to several issues. Rocky or variable soil conditions common here may compromise the effectiveness of your grounding electrode system, which is critical for safety and surge dissipation. Furthermore, heavy tree canopy in these areas can cause line interference during high winds or lead to service drops being damaged. An inspection should verify your grounding resistance and check for vegetation contact with the overhead service mast feeding your home.

For a burning smell with total power loss, treat it as an urgent safety issue and consider calling 911 first. A local master electrician can typically dispatch from a central location like Mary Wood Park and use I-476 to reach most Conshohocken addresses within 5-8 minutes for emergency service. The priority is immediate assessment to locate the source of the burning odor, which often originates at an overloaded breaker, a failing connection on the bus bars, or the service entrance itself.

It's a common sign of an overloaded system, not a normal condition. Your 68-year-old electrical system was designed for a different era; the original cloth-jacketed copper wiring and 100A service panel weren't built to handle the simultaneous loads of modern appliances, multiple computers, and central air conditioning. The voltage drop you experience indicates the wiring and panel are operating at their functional limit, which can lead to overheating and premature failure of components.
