A fault in an electrical circuit where current flows unintentionally from the live conductor to the ground or a grounded surface.
Any unintentional electrical connection between an energized conductor and a grounded object or surface, potentially causing shock, equipment damage, or fire.
Dialectal Variation
British vs American Usage
Differences
The term is identical in both varieties. However, 'ground' in American English is equivalent to 'earth' in British English in general electrical terminology. Despite this, the technical term 'ground fault' is used in both, while 'earth fault' is also common in British English.
Connotations
Identical strong technical/safety connotations in both varieties.
Frequency
Slightly more common in American English due to the standard term 'ground fault circuit interrupter (GFCI)'; in British English, 'earth leakage' or 'earth fault' may be used with similar but not identical technical meanings.

FAQ
Frequently Asked Questions
No. A short circuit is a direct connection between live and neutral conductors. A ground fault is a connection between a live conductor and a grounded surface or object.
Typically in areas with moisture, like bathrooms, kitchens, garages, outdoor outlets, and construction sites, as per most national electrical codes.
Damaged insulation on wires, faulty appliances, water ingress into electrical components, or improper wiring can create a path for current to flow to ground.
Yes. If the fault current is high enough to generate heat but not high enough to trip a standard circuit breaker immediately, it can overheat and ignite surrounding materials.
