Quick answers
The questions we hear most.
Which electrical code applies to my home?
Harford County and Baltimore County enforce the 2023 National Electrical Code. Baltimore City enforces the 2020 edition with its own amendments.
Have Federal Pacific Stab-Lok panels been recalled?
No. The U.S. Consumer Product Safety Commission closed its investigation of Federal Pacific Electric circuit breakers in 1983 without making a safety determination, and there has never been a recall.
Is there still a federal tax credit for a panel upgrade?
Not for work placed in service in 2026. The 25C credit covered panelboards of 200 amps or more, up to $600, only for property placed in service through December 31, 2025.
How much is the Maryland EV charger rebate?
The Maryland Energy Administration's FY2027 rebate pays 50% of eligible costs for one Level 2 charger, up to $700. You apply after the charger is installed and paid for, by 3:00 PM ET on May 31, 2027, while funds last.
Who can pull an electrical permit?
A licensed electrician registered with your county or the city. In Harford County a Harford-licensed master electrician applies; in Baltimore County, a county-registered licensed electrical contractor; in Baltimore City, a contractor registered in ePermits.
