Definitions:

Short-Circuits

Electrical connections that unintentionally direct current along an unintended path, often resulting in excessive current flow.

Ground-Faults

Ground-faults occur when an unintended path forms in an electrical circuit, allowing current to flow directly to the ground, potentially causing shocks or fires.

Short-Circuit

A fault in an electrical circuit where the current goes through an unintended path, often resulting in excessive current flow that can cause damage or fire.

Ungrounded Phase Conductors

These are electrical conductors that are part of a phase in a multi-phase system and do not have a direct electrical connection to ground, potentially leading to unsafe operating conditions if not managed properly.
