Ground Fault
A Ground Fault is a common electrical safety issue that occurs when electricity takes an unsafe path to the ground, often through water, metal, or a person. Think of it like a water leak in electricity - instead of flowing where it should, it's leaking somewhere dangerous. This term is important in electrical repair jobs because fixing and preventing ground faults is critical for safety. When looking at resumes, you might see it mentioned alongside terms like GFCI (Ground Fault Circuit Interrupter), which is a safety device that protects against these issues.
