Licensing requirements
New Jersey
New Jersey requires a Electrical Contractor License through the New Jersey Board of Examiners of Electrical Contractors. Homeowners are exempt for work on their own primary residence.
New York
New York requires a Electrical License (varies by jurisdiction) through the NYC DOB or local jurisdictions. 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 New Jersey or New York, 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 New York uses NEC 2023 and New Jersey uses NEC 2020, there are differences in GFCI coverage:
| Location | New York (NEC 2023) | New Jersey (NEC 2020) |
|---|---|---|
| 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) | |

Is the wire size different in New Jersey vs New York?
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 New Jersey and New York. The ampacity values have not changed since NEC 2017.
Do both New Jersey and New York 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 New Jersey and New York 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.
