530.3 Terms and definitions
530.3.1
control
1) deliberate action resulting in the operation of an apparatus;
2) a device which initiates the operation of an apparatus
[SOURCE: IEV 821-01-28]
530.3.2
isolation
function intended to make dead for reasons of safety all or a discrete section of the electrical
installation by separating the electrical installation, or section, from every source of electric
energy
[SOURCE: IEV 826-17-01]
530.3.3
monitor, verb
acquire a quantity value continuously or sequentially in order to check whether it is within
normal operating limits and, where appropriate, to signal if it passes its tolerance boundaries
[SOURCE: IEV 351-43-03]
530.3.4
switching
function intended to make or break the current in one or more electric circuits
530.3.5
co-ordination of electrical equipment
correct way of selecting electrical devices in series to ensure safety and continuity of service
of the installation taking into account short-circuit protection and/or overload protection and/or
selectivity
530.3.6
safety of electrical installation
safety of human, livestock and property against danger and damage which may arise in the
reasonable use of electrical installations and which is covered by measures for:
– protection against electric shock;
– protection against thermal effects;
– protection against overcurrent;
– protection against fault currents;
– protection against voltage disturbances and measures against o electromagnetic
influences;
– protection against power supply interruption where danger or damage is expected
Note 1 to entry: Continuity of supply may be necessary for certain circuits (e.g. circuits in medical locations,
circuits supplying emergency systems).
530.3.7
continuity of service
quality of an installation which is expressed by the extent to which the operation of an
electrical system approaches the ideal state of freedom from interruption, or which the
operation of electrical system minimizes supply interruption thanks to co-ordination of
electrical devices
530.3.8
back-up protection
overcurrent co-ordination, in short-circuit conditions, of an OCPD in series with another
electrical device where the OCPD, generally but not necessarily on the supply side, effects
the overcurrent protection and prevents any excessive stress on the electrical device
Note 1 to entry: Back-up protection does not cover the combined short-circuit protection.
530.3.9
combined short-circuit protection
overcurrent co-ordination, in short-circuit conditions, of two OCPDs in series, resulting in a
combined short-circuit current capability higher than one OCPD alone
530.3.10
combined short-circuit capability
maximum short-circuit current which can be handled by two short-circuit protective devices in
series
530.3.11
selectivity
co-ordination of the operating characteristics of two or more protective devices such that, on
the incidence of overcurrents or residual currents within stated limits, the device intended to
operate within these limits does so, while the other(s) does (do) not
[SOURCE: IEV 441-17-15, modified]
Note 1 to entry: Distinction is made between series selectivity involving different overcurrent protective
devices passing substantially the same overcurrent and network selectivity involving protective devices passing
different proportions of the overcurrent.
530.3.12
total selectivity
selectivity where only the OCPD on the load side will operate up to the maximum prospective
short-circuit current at its point of installation
530.3.13
partial selectivity
selectivity where the OCPD on the load side only will operate up to a fault current (the
selectivity limit current) less than the maximum prospective short-circuit current at its point of
installation
530.3.14
overcurrent protective device (OCPD)
device provided to interrupt an electric circuit in case the conductor current in the electric
circuit exceeds a predetermined value for a specified duration

generic function.

short-circuit protective device (SCPD)
device intended to protect a circuit or parts of a circuit against short-circuit currents by
interrupting them

generic function.

mechanical switching device, capable of making, carrying and breaking currents under normal
