Residential Panel Upgrades

Residential Panel Upgrades in Pasadena, Annapolis & Columbia, MD

If your home's electrical panel is outdated, overloaded, or struggling to keep up with today's power demands, it may be time for an upgrade. Able Electrical Services, Inc. specializes in residential electrical panel upgrades throughout Pasadena, Annapolis, Columbia, and all of Anne Arundel and Howard Counties in Maryland. Our licensed electricians ensure your home is equipped with a safe, modern panel that meets current code requirements and supports your family's lifestyle.


Older panels — including Federal Pacific and Zinsco brands — are known fire hazards. If your home has a 100-amp panel and you're running modern appliances, EV chargers, or a home addition, an upgrade to 200-amp service is often essential. Able Electrical handles the entire process from permit to inspection.
