GFCI and AFCI upgrades, outlets, and switches in Denver
Two protective devices, two different hazards, and one of them is now required in nearly every part of a house.
A ground-fault circuit interrupter watches for current leaving the circuit by an unintended path, a person included, and opens in a fraction of a second. The 2023 code pushed that protection well past bathrooms and garages, so kitchens now need it on every receptacle regardless of distance from the sink, and basements, laundry areas, and outdoor outlets are covered as well. An arc-fault device does a different job entirely, recognizing the electrical signature of arcing in damaged or loose wiring, and it protects most habitable-room branch circuits in new work.
Older houses complicate the upgrade. An ungrounded two-wire circuit cannot legally take a standard three-prong receptacle, but a ground-fault device is permitted as a replacement when it is labeled as having no equipment ground, which gives real shock protection without pulling new cable through finished walls. Repeated tripping is the other common call, and it is usually the device doing its job on a genuine fault, a shared neutral, or an appliance leaking current, rather than a defective breaker.
what is the difference between GFCI and AFCI?
A GFCI protects people from shock by detecting current leaking out of the circuit to ground. An AFCI protects the building from fire by detecting arcing in damaged wiring or a loose connection, which a standard breaker never sees because the current stays inside normal limits.
why does my GFCI keep tripping?
Because it is finding leakage somewhere on the circuit. Moisture in an exterior box, a failing appliance, and a neutral shared between two circuits are the usual culprits, and the way to isolate it is to unplug everything on that circuit and add loads back one at a time.
can you put a three prong outlet on old two wire wiring?
Only with ground-fault protection and the right labeling. A GFCI receptacle, or a standard receptacle fed downstream of one, may replace a two-prong outlet on an ungrounded circuit, and the code requires it be marked no equipment ground so nobody assumes a ground path that is not there.
