Panel Upgrades & Capacity Planning
Know Your Electrical Limits Before You Hit Them
Many homeowners discover their electrical panel is inadequate only when something fails — a breaker that won't reset, a contractor who says you can't add the circuit you need, or an inspector who won't approve your addition. Proactive capacity planning prevents these surprises. Charm City Electric provides panel and service capacity consulting to help you understand what your current system can handle and plan for what you'll need.

Assessing Your Current Capacity
We perform a full load calculation per NEC Article 220 on your existing electrical service. This involves measuring your actual connected load, calculating the demand load using NEC methods, and comparing that to your service rating. The result tells you exactly how much additional capacity you have — or whether you're already over your safe operational limit.
Planning for Future Loads
If you're planning to add an EV charger (typically 40–50 amps), a hot tub (50–60 amps), a whole-home generator interlock, or a large addition, we help you understand the cumulative impact on your service. We calculate whether your existing panel can accommodate the new loads, whether a service upgrade is needed, and whether load management devices (like an EV charger smart controller) can defer the need for an upgrade.
The Upgrade Path
If an upgrade is needed, we provide a detailed scope covering the service size required, the panel brand and model we recommend, the BGE coordination process, and the typical cost and timeline. This gives you the information you need to budget the project, compare contractor bids, and make an informed decision — before you're in an emergency situation.
