FAQs

What type of electrical outlets are required by code in Greeneville homes today?

Greeneville follows the State of Tennessee’s adoption of the 2017 National Electrical Code (NEC), which specifies that 15-amp or 20-amp, 125-volt, three-slot receptacles are standard for general-purpose branch circuits. All new or replaced receptacles must be listed, grounded, and tamper-resistant (TR). Kitchens, laundry rooms, garages, and workshops generally require 20-amp rated outlets to handle larger appliance loads. Whenever an older two-slot (non-grounded) receptacle is encountered, the safest and code-compliant solution is either to add a grounding conductor or replace the outlet with a GFCI receptacle marked “No Equipment Ground.”

How many outlets should be installed per wall or room to meet modern standards?

Section 210.52(A) of the NEC—enforced by Greeneville’s building department—states that receptacles in living areas must be placed so that no point along the floor line is more than 6 feet from an outlet. Practically, this means an outlet at least every 12 feet of wall space and on any wall wider than 24 inches. Kitchens require at least two small-appliance branch circuits, and countertop receptacles must be installed so no point is more than 24 inches from an outlet. Bathrooms need at least one GFCI-protected outlet within 3 feet of the basin. Providing these minimum numbers not only satisfies code but also reduces extension-cord use, which is a common fire hazard.

When are GFCI and AFCI outlets necessary, and what’s the difference?

• GFCI (Ground-Fault Circuit-Interrupter) outlets monitor the imbalance between hot and neutral conductors and trip at 4–6 mA; they are required anywhere water or dampness is present—kitchens, bathrooms, laundry areas, garages, unfinished basements, crawl spaces, exterior locations, and within 6 feet of any sink. • AFCI (Arc-Fault Circuit-Interrupter) outlets or breakers detect series and parallel arcing that can ignite fires. The 2017 NEC requires AFCI protection for most 120-volt, 15- and 20-amp branch circuits serving outlets in dwelling unit bedrooms, living rooms, dining rooms, hallways, and closets. Some manufacturers sell dual-function receptacles that provide both GFCI and AFCI protection, which is useful when the panel location makes breaker replacement difficult.

Are tamper-resistant outlets mandatory, and how do they enhance safety?

Yes. Since the 2011 NEC (continued in 2017), tamper-resistant (TR) receptacles are required in all areas of a dwelling, including bedrooms, hallways, kitchens, garages, and outdoors. TR outlets contain internal spring-loaded shutters that remain closed until equal pressure is applied to both openings simultaneously—something a plug does but a child’s fingertip or toy does not. Studies by the National Fire Protection Association show that TR devices reduce outlet-related childhood shocks by over 80 %. Because TR receptacles cost only about a dollar more than standard models, they are considered one of the most cost-effective safety upgrades available.

What special considerations apply to outdoor or damp-location outlets in Greeneville’s climate?

Outdoor receptacles must be GFCI-protected, housed in a weather-resistant (WR) receptacle, and covered by an "in-use" (bubble-type) cover that keeps the plug and cord dry even while in service. Boxes must be rated for wet locations, and conductors should be routed in non-metallic Schedule 80 PVC or listed metallic conduit with proper bushings. Because Greeneville experiences below-freezing temperatures and summer humidity, exterior devices should be rated for ‑40 °F to 140 °F and have stainless-steel or brass screws to prevent corrosion. For porches or covered patios (damp, not wet locations), a WR receptacle with a weatherproof cover is still required, but an in-use cover may be omitted if the outlet is only energized while a plug is inserted and the cover is closed.

Can I replace or add outlets myself, or should I hire a licensed Greeneville electrician?

Homeowners in Greeneville may perform their own electrical work on a single-family residence they own and occupy, but they must obtain a permit, follow NEC/Tennessee Building Code requirements, and schedule inspections. If you are unfamiliar with load calculations, bonding, or conductor sizing, hiring a Tennessee-licensed electrical contractor is strongly recommended. Professionals can pull permits, ensure outlets are properly GFCI/AFCI protected, verify grounding integrity, and use calibrated torque screwdrivers to meet manufacturer lug-torque specifications—vital for preventing loose, heat-generating connections. Improper DIY outlet work is a leading cause of household electrical fires, and insurance claims can be denied when non-permitted wiring is discovered.
