Serving Smyrna & Cobb County, Georgia
Much of Smyrna's housing stock went up decades before anyone imagined charging a car in the garage. Jonquil Electric upgrades panels, installs EV chargers, runs load calculations, and inspects electrical systems — built for the homes this county actually has.
The short answer
Jonquil Electric provides electrical panel upgrades and replacements, Level 2 EV charger installation, solar-readiness load calculations, and electrical safety inspections for homes in Smyrna, Vinings, Mableton, and surrounding Cobb County — with permits handled through the City of Smyrna and Cobb County.
Find your era
Your home's construction era says a lot about the panel in your garage or basement. Pick a decade to see what was standard when your house went up — and whether it's still standard now.
Pre-1960
Screw-in fuses and 60-amp service, sized for a refrigerator and lights — not a modern kitchen, HVAC, and electronics.
Typically due for replacement1950s–1980s
FPE Stab-Lok panels were installed in millions of U.S. homes in this window and are flagged by many insurers and home inspectors over breaker-failure concerns.
Flagged by insurers & inspectors1975–1995
Standard breaker panels, usually 100–150 amps. Safe when maintained — but often maxed out once an EV charger or heat pump enters the picture.
Capacity check recommended1995–Today
200-amp service with room for EV charging, solar interconnection, and modern appliance loads. This is where an upgrade takes your home.
Current standardEras overlap because panel installations lag construction trends. The only way to know what you have is to look — or have us look. If your panel door says Federal Pacific or Stab-Lok, start with a panel consultation.
Services
Everything we do connects to the same question: can your electrical system support the way you live now — and the way you'll live in five years?
Replace aging or flagged panels — including Federal Pacific Stab-Lok units — and upgrade 100A service to a modern 200A panel with room to grow. Permitted through the City of Smyrna.
