03 — Where GFCI Applies
GFCI Protection Under Virginia’s Current Code
Virginia’s reasoning for the condenser change was practical: a GFCI’s trip setting and the normal leakage current of an outdoor air conditioner unit are set by separate standards that do not always agree, and a nuisance trip in extreme heat carries its own risk.
Basements and sump pumps
The basement change is broader than it sounds. Earlier editions focused on unfinished basement areas, while the current list covers the whole basement, finished rooms included, and sump pumps were added to the list of equipment needing GFCI protection. In a home with a finished basement or a sump pit, a new or replaced receptacle there is planned with that protection.
04 — GFCI Self-Test
GFCIs That Test Themselves, and When They Wear Out
Self-testing GFCIs came after field studies found GFCIs in service that no longer worked, which led the Consumer Product Safety Commission to request a change in the safety standard.
UL Solutions explains that since June 29, 2015, GFCI receptacles and circuit breakers have had to be manufactured with an auto-monitoring, or self-test, function. At end of life, the UL 943 standard calls for the device to shut off power to itself and the outlets it protects, with a light or sound allowed instead for two specific failure modes.
That means an outlet that will not reset, along with the outlets beyond it, can be a GFCI that has reached end of life, with no wiring fault at all. Devices made before that date were not built to the self-test requirement, and older stock could still be sold for a time, so a house built in 2016 may still have some GFCIs without the feature.
Self-testing does not replace the button. UL notes the self-test cannot check the trip solenoid or whether the contacts are welded, which only an actual trip reveals, and the Electrical Safety Foundation International recommends pressing TEST every month. If a plugged-in nightlight does not go off, the GFCI is not working properly.
05 — AFCI Tripping
When an AFCI Breaker Keeps Tripping
Many newer homes have arc-fault protection on bedroom and living-area circuits. It is tempting to blame the breaker when one trips repeatedly, but in a 2025 survey of electrical contractors in Georgia and South Carolina, the Electrical Safety Foundation International found that 84 percent of tripped-AFCI service calls were caused by arc faults, and it listed short circuits, overloaded circuits, and defective devices among the other causes.
Manufacturers do describe nuisance trips, where an appliance, such as a new vacuum cleaner, has an electrical signature that the breaker reads as arcing. The practical test is to run that appliance on a different circuit. If the breaker still trips without it, the circuit needs a closer look for damaged cable, a loose connection, or two circuits sharing one neutral wire.
The Consumer Product Safety Commission notes that AFCIs address fire hazards while GFCIs address shock. A tripping AFCI is never swapped for a standard breaker.

Common Outlet Problems in Newer Suffolk Homes
The test results decide whether the fix is a device, a connection, or the circuit itself.
07 — Process
From Walk-Through to Permit to Tested GFCI
Walk the rooms and outbuildings
We note each outlet location, its use, and whether GFCI or tamper-resistant devices apply.
File the Suffolk permit
We list each new circuit and its size on Suffolk’s electrical application, file the permit, and request the city’s inspection. We can pick the day; the city sets the time, and an adult has to be there for it.
Install and test
Each GFCI we install is tripped and reset before we leave.
08 — Proof
Two Jobs, One Visit
A customer asked for new outlets in the house and a 14-50 receptacle in the garage, and had both finished in a single visit.
