This document applies to switching device for islanding, hereafter referred to as SDFI, for household and similar uses, primarily intended to be used for energy efficiency (EE) purposes with local production or local storage of energy, or with both.
SDFI are intended to be installed in low voltage prosumer electrical installations (PEI) able to operate in island mode as defined in IEC 60364-8-82, so called islandable PEI.
SDFI are used to disconnect the PEI from the grid to allow operating the PEI in island mode and further reconnect the PEI to the grid.
They are intended to be used in islandable PEI which operate:
– in connected mode (direct feeding mode or reverse feeding mode), and
– in island mode,
as defined in IEC 60364-8-82.
NOTE 1 See definitions 3.10 and 3.13 of island mode and for connected mode respectively.
NOTE 2 Switching of a PEI to island mode can be subject to local regulations (grid codes) or to specific agreement with system operators. Reverse feeding is also usually subject to local regulations (grid codes). SDFI are part of the electrical installation.
This document applies to SDFI for operation in AC single or multiphase main circuits with rated voltages not exceeding 440 V AC, frequencies of 50 Hz, 60 Hz or 50/60 Hz. They are intended to be used in installations with prospective short circuit currents not exceeding 25 000 A.
NOTE 3 DC operations are not covered by this edition and are kept under consideration for a future revision of this document.
The SDFI is composed at least of one switching unit (SU) and a control unit (CU) to monitor its switching operations from grid connected to island mode and reverse wise.
The SDFI can be provided with a communication interface for exchange with external systems such as the Customer Energy Manager (CEM) defined in IEC 63402 series.
According to the intended use, the SDFI can be interlocked with a system referencing conductor switching device (SRCSD) according to IEC 63445 or it can be integrated with a SRCSD in a single unit.
NOTE 4 According to its intended use, the SDFI can also be used as an interface switch with the interface protection (integrated or not). See 3.19 and 3.20.
SDFI are intended for use in circuits where protection against electrical shock and overcurrent is provided according to installation rules for low voltage electrical installations, unless the SDFI already contains such protective function. SDFI are not requested to provide isolation function and overcurrent protection according to IEC 60364-8-82. However, the isolation function can be provided by a SDFI fulfilling the requirements of the relevant product standards.
SDFI are installed by instructed persons (IEC 60050-195:2021, 195-04-02) or skilled persons (IEC 60050-195:2021, 195-04-01). They are intended to be used by ordinary persons (IEC 60005-195:2021, 195-04-03) and do not require maintenance.
It is important to note that the main overcurrent protective device of installations cannot be used as a SDFI in single dwellings or similar islandable PEI (see Clause D.5 of IEC 60364-8-82:2022)

The purpose of this document is to describe product classes and properties, representing the miniature circuit-breaker (MCB), to become a part of the IEC 61360-4: IEC Common Data Dictionary (IEC CDD). It includes data required for product selection as well as data required for engineering.
This document intends, as a contribution to the IEC Common Data Dictionary, to be used by catalogue consortia, other database standards and software as a data reference for circuit-breakers and similar equipment for household use.
NOTE In the future, it is intended to extend the IEC 63508 DB to other types of products e.g. arc fault detection devices (AFDDs), residual current circuit breakers (RCCBs), residual circuit breaker with overcurrent protection (RCBOs).

The OpRa scope is the definition of a minimum set of Public Transport raw data needed to enable PT quantitative analysis.
OpRa does not go into the domain of service quality measurement and reporting: service quality analysis will use data provided by OpRa, but quality definition remains a contractual level issue between a Public Transport Authority and a Public Transport Operator or an operator’s internal choice for a purely private service. OpRa reports unbiased actual data (i.e. measured or observed), described and aggregated in a shared and understandable way.
OpRa focuses mainly on observed/measured and registered information, i.e. information which cannot be changed anymore in the future. This information is mainly an output of the domain “operations monitoring & control" as defined by Transmodel.
Based on the actual service, including delays and cancelled vehicle journeys, etc., OpRa considers the recorded reality of operation, either through individual observed and registered data at a given sampling interval (raw data) or in an aggregate way (indicators) and provides the data exchange format.
The approach documented in detail in this document is coherent with EU Directive 2010/40. It relates to the Article 4 of the Delegated Regulation EU 2017/1926 [16], as regards the historic data. OpRa proposes to complement NeTEx (dedicated to the static scheduled information), for the historic data, based on the underlying conceptual data reference model Transmodel EN 12896, similarly to the requirement of the Delegated Regulation EU 2017/1926 referring to the static scheduled information2.

This part of IEC 61076 specifies circular connectors with bayonet locking size B12, B17, B23 and B40, typically used for power, signal and data transmissions in industrial applications.
These connectors consist of fixed and free connectors either rewirable or non-rewirable.
NOTE B indicates that the connector is equipped with bayonet locking, while 12, 17, 23, 40 are the approximate dimensions in millimetres of the contact carrier diameter of these circular connectors.
Power contacts of male connectors are round contacts with Ø 1 mm, Ø 1,5 mm, Ø 1,8 mm, Ø 2,25 mm and Ø 4 mm, with current ratings up to 64 A per pole and rated voltage of 50 V, 300 V or 600 V AC/DC. Power contact groups are classified by type and identified throughout this document as “P” followed by two digits “01” through “09” (see 4.3, Table 1).
Signal contacts of male connectors are round contacts with Ø 1 mm and Ø 1,8 mm, with current ratings up to 20 A per pole and rated voltage of 50 V AC/DC. Signal contact groups are classified by type and identified throughout this document as “S” followed by “0”, “1”, or “2” (see 4.3, Table 2).
Male data contacts are round with Ø 0,8 mm and Ø 1 mm, with current ratings up to 4 A and rated voltage of 50 V AC/DC, Data modules are classified by type and identified throughout this document as “D” followed by “1”, or “2” (see 4.3, Table 3). D1 modules provide data transmission with frequencies from 1 MHz to 100 MHz; D2 modules provide data transmission with frequencies from 0,1 MHz to 600 MHz.
Besides the size of their bayonet locking (B12, B17, B23 or B40), connectors according to this document can be identified by data module (D) and complementing power (P) and signal (S) contact groups and optionally by number of poles, and finally by their application.
These connectors are designated for two main target applications, which differ as follows:
– Application A is for data transmission with power over data.
– Application B is for data transmission without power over data.
Connectors with power, signal and data contacts of the same gender are intended to also transmit power over the data contacts (application A), while connectors with data contacts not of the same gender of power and signal contacts are not intended to transmit power over the data contacts (application B).
The codings provided by this document prevent the mating to any other connector with similarly sized interfaces covered by this document.

The present document is aimed at defining the topology and level of analysis to assess the energy efficiency of mobile networks. Within the scope of the present document there is also the focus on the most energy consuming part, which is the radio access part of the mobile networks, and namely there are radio base stations, backhauling systems, radio controllers and other infrastructure radio site equipment. The covered technologies are GSM, UMTS, LTE and 5G New Radio (NR). In particular the present document defines metrics for mobile network energy efficiency and methods for assessing (and measuring) energy efficiency in operational networks. The purpose of the present document is to allow better comprehension of networks energy efficiency, in particular considering the networks' evolution in different periods in time. Aiming to consider also the slicing approach of the networks from 5G onwards the metrics are extended to the latency of the network itself related to the energy consumed, additionally to the metrics based on traffic and on coverage, already existing for legacy networks and still valid. The present document deals with both a homogeneous and heterogeneous "network" considering a network whose size and scale could be defined by topologic, geographic or demographic boundaries. For networks defined by topologic boundaries, a possible example of a network covered by the present document consists of a control node (whenever applicable), its supported access nodes as well as the related network elements. Networks could be defined by geographic boundaries, such as city-wide, national or continental networks and could be defined by demographic boundaries, such as urban or rural networks. The present document applies to the so-called "partial" networks for which a measurement method is also recommended. The present document extends the measurements in partial networks to wider so-called "total" networks energy efficiency estimations (i.e. the network in a geographic area, the network in a whole country, the network of a MNO, etc.). Terminal (end-user) equipment is outside the scope of the present document and is not considered in the energy efficiency measurement.
