3.10 protective conductor protective grounding conductor
conductor, not normally carrying current, used for some measure of protection against electric shock, for electrically connecting any of the following parts of electrical equipment to the craft's ground/earth and to the shore AC grounding conductor through the shore power cable:
a) exposed conductive parts (3.15) of electrical equipment; b) extraneous conductive parts (3.33); c) the main grounding (earthing) terminal; d) earth electrode(s);
e) the earth point of a source, or an artificial neutral 3.11 live conductor
conductor or conductive part intended to be energized in normal use, including a neutral conductor (3.9)
3.12 active (phase) conductor
conductor that is maintained at a difference of potential from the neutral conductor (3.9) or protective conductor (3.10)
Note 1 to entry: In a system that does not include a neutral or protective conductor, all conductors are considered active conductors.
3.13 ignition-protected
<equipment> designed and constructed to give protection against ignition of surrounding flammable gases Note 1 to entry: The protection against ignition of surrounding flammable gases is covered in ISO 8846:1990.
3.14 system voltage nominal voltage supplied to the craft from a power source
3.15 exposed conductive part
conductive part of electrical equipment, which can be touched and which is not normally live, but which can become live under fault conditions
3.16 panel board switchboard
assembly of devices for the purpose of controlling and/or distributing electrical power Note 1 to entry: It can include devices such as circuit breakers, fuses (3.29), switches, instruments, and indicators.
3.17 polarized system
system in which the live conductors (3.11) (active and neutral) are connected in the same relation to all terminals on devices or receptacles (socket outlets) in a circuit
