IEC 61000-4-30:2025 defines the methods for measurement and interpretation of results for power quality parameters in AC power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method’s implementation. This document addresses measurement methods for in-situ measurements. This document covers two classes of measurement methods (Class A and Class S). The classes of measurement are specified in Clause 4. NOTE 1 In this document, “A” stands for “advanced” and “S” stands for “surveys”. Measurement of parameters covered by this document is limited to conducted phenomena in power systems. The power quality parameters considered in this document are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, rapid voltage changes, mains communicating system (MCS) voltages, magnitude of current, harmonic currents, interharmonic currents and current unbalance. Emissions in the 2 kHz to 150 kHz range are considered in Annex C and Annex D. Depending on the purpose of the measurement, all or a subset of the phenomena on this list can be measured. NOTE 2 Test methods for verifying compliance with this document can be found in IEC 62586-2. NOTE 3 The effects of transducers inserted between the power system and the instrument are acknowledged but not addressed in detail in this document. Guidance about effects of transducers can be found IEC TR 61869-103. This fourth edition cancels and replaces the third edition published in 2015.

- detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by
processing (at a minimum) the optical effect of an internal arc-fault, and
- operate mitigation device (either external or combined)
in order to minimize the effects of the internal arc-fault (see Figure 1).
For the purpose of this document the terms "light" or "optical" covers more than visible spectra.
They may cover also, for example, infrared or ultraviolet electromagnetic radiations (see
Annex D).
For combined-type IACD, this document is considered in addition to the relevant product
standard for internal arc-fault mitigation devices (IARD per IEC TS 63107:2020). Compliance
to the relevant product standard is mandatory and cannot be claimed by testing to this document
alone.
NOTE 1 Low-voltage switchgear and controlgear assemblies are usually described by IEC 61439 series.
[Figure 1]
Therefore, this document covers the following:
- internal arc-fault control device (stand-alone, multifunction or combined);
- one or more associated sensor(s) used to detect optical effect of the internal arc-fault;
- sensor(s), sensing another physical effect, to confirm the fault;
- associated or combined mitigation device.
An IACD is not intended to trigger under normal operation of low-voltage switchgear and
controlgear (i.e. absence of internal arc-fault), including normal arcing associated with
operation of disconnecting and switching devices.
This document only covers the following methods:
- optical detection of the light caused by an internal arc-fault;
- optional confirmation of internal arc-fault by line current measurement.
Many different conductive materials could be used in LV assemblies (e.g. steel, copper,
aluminium). Nevertheless, tests specified in this document are deemed to represent the most
critical and challenging conditions for arc-detection and cover all combinations of conductive
materials.
NOTE 2 Compared to other materials (e.g. steel, aluminium), copper leads to a lower optical radiation energy.
The rated voltage of the assembly in which an IACD is installed does not exceed 1 000 V AC.
Such devices are designed to be operated and maintained by skilled persons only.
This document does not cover:
- DC internal arc-fault detection and control;
- overcurrent relays;
- AFDD (arc-fault detection devices) as defined by IEC 62606;
- guidance on installation within assemblies;
NOTE 3 The integration of an IACD into an assembly is described in IEC TS 63107.
- use with additional measures needed for installation and operation within explosive
atmospheres. These are given in IEC 60079 series documents;
- requirements for embedded software and firmware design rules; for this subject, the
manufacturer is responsible for taking additional safety measures;
NOTE 4 IEC TR 63201 describes rules for firmware and embedded software development preventing errors in
software.
- cybersecurity aspects; for this subject, the manufacturer is responsible for taking additional
safety measures;
NOTE 5 See IEC TS 63208.
- mobile applications.
NOTE 6 Even when addressing internal arc-fault mitigation devices, this document does not supersede any other
relevant product standard (e.g. IEC 60947-2 or IEC 60947-9-1).
NOTE 7 DC arcing fault phenomena are under consideration. Further investigation is needed to comprehend DC
arcing phenomena and required sensing.

This International Standard applies to Source Switching Equipment, hereafter referred to as SSE(s), for household and similar uses, primarily intended to be used for Energy Efficiency purposes with local production and/or storage of energy.
This standard has been drafted following principles of:
- IEC guides 118 and 119 for Energy Efficiency;
- IEC guide 110 for safety.
SSEs are intended to be installed in low voltage prosumer electrical installations (PEI) to deliver the electrical energy:
- either to current-using equipment (direct feeding mode or island mode);
- or to the grid (reverse feeding mode).
SSEs are intended to select and/or combine two power sources (e.g. selected among grid, local power source, storage units) within an Electrical Energy Management system (EEMS). SSEs may also be used for backup supply.
NOTE SSEs capable to select more than two sources are under consideration.
SSEs are part of the fixed electrical installation.
This standard applies to SSEs for operation in:
- AC single or multiphase circuits with rated voltages not exceeding 440 V AC, frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A. They are intended to be used in installations with prospective short circuit current not exceeding 25 000 A, or
- DC circuits. SSE for DC circuits are under consideration (next edition).
SSEs may be operated:
- manually (M-SSE), or
- remotely (R-SSE), or
- automatically (A-SSE), or
- a combination of the above methods of operation, e.g. manual and remote.
SSEs are constructed either as Combined-SSEs (C-SSEs, based on dedicated products suc as circuit breakers, switches or contactors) or Non-Combined SSEs (NC-SSEs).
SSEs are intended for use in circuits where protection against electrical shock and over-current according to IEC 60364 is provided, unless the SSE already contains such protective function.
SSEs are normally installed by instructed persons (IEC 60050-195:1998, 195-04-02) or skilled persons (IEC 60050-195:1998, 195-04-01). SSEs are normally used by ordinary persons (IEC 60005-195:1998, 195-04-03) and do not require maintenance.
The requirements of this standard apply for standard environmental 420 conditions as given in clause 7. They are applicable to SSEs intended for use in an environment with pollution degree 2 and overvoltage categories III according to IEC 60664-1:2020. SSEs have at least a degree of protection IP 20 according to IEC 60529. Additional requirements may be necessary for devices used in locations having more severe environmental conditions.
SSEs do not, by their nature, provide an isolation function nor the overcurrent protection. However, isolation and overcurrent protection functions as covered by relevant product standards may be provided by Combined SSEs.
In some countries, it is not permitted to have synchronization of local sources with the grid for particular grid conditions, e.g. when fluctuations of the grid voltage or frequency are outside the tolerance limits.
This document does not apply to transfer switching equipment (TSE) intended to be used by skilled persons, as covered by IEC 60947-6-1:2021.

1.1.1 Equipment included in scope
Replacement:
This part of IEC 61010 specifies safety requirements and related verification tests for control equipment and/or their associated peripherals.
Some equipment examples are:
- programmable logic controller (PLC);
- programmable automation controller (PAC);
- distributed control systems (DCS);
- industrial PC (computers) and panel PC;
- programming and debugging tools (PADTs);
- displays and human-machine interfaces (HMI);
- any product performing the function of control equipment and/or their associated peripherals;
- positioners; and
- control equipment which have as their intended use the command and control of machines, automated manufacturing and industrial processes, e.g. discrete and continuous control.
Components of the above named equipment and in the scope of this standard are e.g.:
- (auxiliary) stand-alone power supplies;
- peripherals such as digital and analogue I/O,
- remote-I/O;
- industrial network equipment, embedded or standalone (e.g. switches, routers, wireless base station).
Control equipment and their associated peripherals are intended to be used in an industrial environment and may be provided as OPEN or ENCLOSED EQUIPMENT.
NOTE 1 Control equipment intended also for use in other environments or for other purposes (example: for use in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have additional conformity requirements defined by the safety standard(s) for these applications. These requirements can involve as example: insulation, spacings and power restrictions.
NOTE 2 Computing devices and similar equipment within the scope of IEC 60950 (planned to be replaced by IEC 62368) and conforming to its requirements are considered to be suitable for use with control equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in IEC 61010-1:2010, 5.4.4 second paragraph.
Control equipment covered in this standard is typically intended 237 for use in OVERVOLTAGE CATEGORY II (IEC 60664-1) in low-voltage installations, where the RATED equipment supply voltage does not exceed AC. 1 000 V r.m.s. (50/60 Hz), or DC 1 000 V.
Where control equipment is intended for installation to supply systems with overvoltage category III or IV, additional requirements are identified in Annex K.
The requirements of ISO/IEC Guide 51 and IEC Guide 104, as they relate to this part of IEC 61010, are incorporated herein.
1.1.2 Equipment excluded from scope
Replacement:
This standard does not deal with aspects of the overall automated system, e.g. a complete assembly line. Control equipment (e.g. DCS and PLC), their application program and their associated peripherals are considered as components (components in this context are items which perform no useful function by themselves) of an overall automated system.
Since control equipment (e.g. DCS and PLC) are component devices, safety considerations for the overall automated system including installation and application are beyond the scope of this standard. Refer to IEC 60364 series of standards or applicable national/local regulations for electrical installation and guidelines.
1.2.1 Aspects included in scope
Replace first sentence:
The purpose of the requirements of this standard is to ensure that all HAZARDs to the OPERATOR, SERVICE PERSONNEL and the surrounding area are reduced to a tolerable level.
NOTE By using the terms "OPERATOR" and "SERVICE PERSONNEL" this standard considers the perception of HAZARDS depending on training and skills. Annex AA gives a general approach in this regard.
