What AFCI and GFCI do
These are two different safety devices, and your home probably needs both. GFCI — ground-fault circuit interrupter — watches for electricity leaking where it shouldn't, like through water or a person. It cuts power in a fraction of a second. AFCI — arc-fault circuit interrupter — watches for dangerous sparking inside walls, the kind that starts fires. One stops shocks. The other stops fires.
Where code requires them
GFCI protection is required anywhere water and electricity meet: kitchens, bathrooms, laundry rooms, garages, basements, and outdoors. AFCI is required in bedrooms, living rooms, and most other living spaces in new work. If your Alexandria home predates these rules — and most do — your circuits have neither.
Breakers or outlets?
Both work. A GFCI or AFCI breaker in the panel protects the whole circuit. A GFCI outlet protects everything plugged into it and downstream. Breakers cost more but cover everything; outlets are cheaper per spot but you need more of them. We'll recommend the mix that fits your panel and your budget.
The nuisance-tripping question
"Won't these trip all the time?" Modern AFCIs had teething problems years ago, but today's versions are far better. If one keeps tripping, that's usually not the device's fault — it's finding a real problem: a damaged cord, a failing appliance, or loose wiring. We track down the cause instead of just resetting it.
When protection keeps tripping, listen to it
A GFCI or AFCI that trips once and resets fine is doing its job. One that trips every day is telling you something. The usual culprits: a space heater with a damaged cord, a bathroom outlet with moisture inside the box, an old appliance leaking current, or — the serious one — damaged wiring inside a wall. Here's what not to do: don't replace the GFCI with a regular outlet to "stop the tripping." That's like unplugging a smoke detector because it beeps. When we get a tripping call, we don't just reset it — we isolate the circuit, test each device on it, and find the fault. Nine times out of ten, the protection was right.
