Licensing requirements
Georgia
Georgia requires a Electrical Contractor License through the Georgia Construction Industry Licensing Board. Homeowners are exempt for work on their own primary residence.
Tennessee
Tennessee requires a Electrical Contractor License through the Tennessee Board for Licensing Contractors. Homeowners are exempt for work on their own primary residence.
Wire sizing is identical. NEC Table 310.16 ampacity values have not changed since NEC 2017. Whether you are wiring in Georgia or Tennessee, a 20A circuit uses 12 AWG copper and a 30A circuit uses 10 AWG copper. The differences between states are in code enforcement, not in the wire sizing itself.
GFCI requirement differences
Because Georgia uses NEC 2023 and Tennessee uses NEC 2017, there are differences in GFCI coverage:
| Location | Georgia (NEC 2023) | Tennessee (NEC 2017) |
|---|---|---|
| Kitchen | All receptacles including refrigerator | Countertop within 6 ft of sink only |
| Basement | All areas (finished and unfinished) | Unfinished areas only |
| Laundry | All laundry receptacles | Within 6 ft of sink |
| Bathroom | All receptacles (same in both) | |
| Outdoor | All receptacles (same in both) | |
| Garage | All receptacles (same in both) | |
Frequently asked questions
Which state has stricter electrical codes, Georgia or Tennessee?
Georgia has stricter enforcement with a score of 80/100 vs 72/100. The score reflects NEC edition recency, licensing requirements, permit enforcement, and state amendments.
Is my electrician license from Georgia valid in Tennessee?
Electrician licenses are generally not transferable between states. If you hold a license in Georgia, you will typically need to apply separately in Tennessee. Some states offer reciprocity agreements, but these vary. Contact the licensing authority in Tennessee directly for requirements.
Is the wire size different in Georgia vs Tennessee?
No. Wire sizing per NEC Table 310.16 is identical regardless of which NEC edition a state enforces. A 20A circuit requires 12 AWG copper in both Georgia and Tennessee. The ampacity values have not changed since NEC 2017.
Do both Georgia and Tennessee require electrical permits?
Both states require electrical permits for most work. Common permit-required projects in both states include new circuits, panel upgrades, service changes, and EV charger installations.
Does the NEC edition difference between Georgia and Tennessee matter for my project?
For most residential work (circuits, outlets, fixtures), the NEC edition difference has minimal practical impact because wire sizing tables are unchanged. The biggest difference is GFCI coverage: NEC 2023 requires GFCI in all kitchen outlets and finished basements, while older editions are narrower. If you are doing a kitchen or basement remodel, the edition difference matters.
