Arc Fault
Electricity jumping a gap at a loose or damaged connection, creating sparks at thousands of degrees inside walls. The leading ignition source AFCI breakers are designed to detect.
Arcs happen where connections degrade: a backstabbed outlet letting go, a nail nicking a cable, a cord crushed under furniture, a splice twisted by hand and taped. The arc itself draws modest current, far below the breaker's trip point, while burning hot enough to ignite wood framing and insulation. That gap in protection is why AFCI breakers exist: they recognize the electrical noise signature of arcing and trip on it.
Audible clues deserve respect: crackling, buzzing or sizzling from an outlet, switch or the panel is arcing happening now, and warm cover plates or a faint fish-like plastic smell are its thermal fingerprints. These symptoms move a repair from "schedule it" to "today."
Talking to a contractor about this?
Run the project past a licensed electrical pro first. Calls are answered around the clock and routed to a pro serving your area.
- Ground Wire (Equipment Ground) : The bare or green wire that carries no current in normal use.
- Grounding Rod (Grounding Electrode) : The 8-foot copper-clad rod driven into the soil near your meter, connecting your electrical system to the earth itself.
- Bonding : Connecting all the metal parts that could become energized (panels, pipes, pool equipment, gas lines) so they sit at the same voltage and faults trip breakers instead of waiting for a person.
- Ungrounded (Two-Wire) Circuits : Pre-1960s circuits with only hot and neutral, no ground conductor.
