3R Electric LLC is a licensed North Carolina electrical contractor based in Chapel Hill, doing electrical work for homeowners and businesses across Orange County, Durham and north Chatham County.
The work ranges across everything a building’s electrical system does: the service and the panel, the wiring inside the walls, the lights and outlets people use every day, and the new loads that keep arriving, from EV chargers and heat pumps to generators for storm season.
Old houses, new loads
This part of North Carolina asks a lot of an electrician. Houses near campus and in old Durham and Hillsborough can still carry knob-and-tube. Neighborhoods built in the 1960s and ’70s bring aluminum branch wiring and panel brands worth replacing. Newer homes in Southern Village, Meadowmont and north Chatham want chargers, generators and finished basements. Every one of those jobs starts the same way: find out what’s actually there before deciding what to do.
How we work
We test before we guess, explain what we found in plain words, give you the price before work starts, and pull the permit when the job needs one. The work should be neat, labeled and ready for inspection.
Licensed in North Carolina

What a house tells us
The year it was built is the first clue.
- Before 1940
Knob-and-tube
Cloth-covered wire on ceramic knobs, no ground. Still live in some houses near campus and in old Durham and Hillsborough.
- 1940s–50s
Fuses & two-prong
Small fuse-box services and ungrounded outlets. Most have been upgraded once; many need it again.
- 1965–73
Aluminum branch wiring
Used in many ranches and split-levels of the era. Safe only with properly repaired connections.
- 1960s–80s
FPE & Zinsco panels
Panel brands that many electricians recommend replacing. Common in houses from these decades.
- 1990s–today
New loads
AFCI and GFCI protection, then EV chargers, heat pumps, generators and finished basements.
