CABLE AND CIRCUIT FAILURE MODES
Definitions (continued)
– Conductor-to-Conductor Short – An abnormal connection (including an arc)
of relatively low impedance between two conductors. A conductor-to-conductor short between an energized conductor of a grounded circuit and a
grounded conductor results in a ground fault. A conductor-to-conductor short
between an energized conductor and a non-grounded or neutral conductor
results in a hot short. Conductor-to-conductor shorts between an energized
conductor of an ungrounded circuit and the reference ground or neutral
conductor(s) has the same functional impact as a ground fault.
