18 IEC and IEC & 2 Standards compliance to meet your needs. A fully compliant system with guaranteed consistency between electrical devices and equipment. IEC standardisation that integrates security, availability and reliability in its recommendations. LV functional switchboards that are already fully compliant, for assembly manufacturer s peace of mind. 100% compliant with IEC IEC & 2 Standard 18

19 Standards Compliance The 10 main functions of the IEC and IEC Standards The IEC60439 and IEC Standards contribute to achieving three basic goals: safety, continuity of service and compliance with end user requirements Safety Voltage stress withstand capability Insulation to withstand longterm voltages. Transient and temporary overvoltages guaranteed through clearances, creepage distances and solid insulation. Currentcarrying capability Protect against burns by limiting excessive temperatures: when any single circuit is continuously loaded to its rated current when any circuit is continuously loaded to its rated current multiplied by its rated diversity factor. Shortcircuit withstand capability Withstand shortcircuit thanks to protection devices, shortcircuit coordination, and capability to withstand the stresses caused by shortcircuit currents in all conductors. Protection against electric shock Hazardous live parts are not accessible (basic insulation protection). Accessible conductive parts are not hazardous to peoples lives (fault protection and continuity of protective equipotential bonding). Protection against fire or explosion hazard Protect people against fire hazards: resistance to internal glowing faulty elements through incorporating protective materials and design provisions. Continuity of service Maintenance and modification capability Capability to preserve continuity of supply without impairing safety during assembly maintenance or modification, through fault protection and optional removable parts. Electromagnetic compatibility Avoid generation of E disturbances through incorporating electronic devices that comply with the relevant E Standards, and their correct installation. Compliance with end user requirements End user s ability to operate the electrical installation End user s ability to operate is achieved by: the electrical diagram and specifications (voltages, coordination, etc.) through selecting, installing and wiring the appropriate switching devices. providing easy access to humanmachine interfaces (HMIs) and other operational equipment/devices. Capability to be transported and installed onsite Capable of handling, transport, storage and installation constraints. Can be constructed onsite and connected through custom enclosure design the to fit external terminals. Protection of the assembly against environmental conditions Assembly protection against mechanical and atmospheric conditions through using protective materials and incorporating specific enclosure design. 19

20 Standards Compliance Okken... goes beyond the IEC standard Functional panels for large industrial sites Voltage stress withstand capability All busbar supports are designed to meet minimum creepage distances required by the IEC standard. The main busbar is within a partitioned compartment at the top of the switchboard. The distribution busbar is installed in a partitioned compartment to the rear of the switchboard. Shortcircuit withstand capability Internal arc risks are reduced due to the Polyfast system and three confinement levels: at the functional unit (AS/NZS Annex ZD), at the column (IEC 61641) and at the switchboard. The partitioned terminals incorporate the Polyfast system to ensure electrical insulation between the upstream circuit breaker and the double contact clamps on the main busbar. Rated conditional shortcircuit current (Isc) up to 150 ka. 100% IEC IEC &2 Protection against electrical shocks Superior safety and protection systems, preventing onload operation to ensure safer operation and maintenance. Live parts are protected by screens providing an IP20 degree of protection. Busbars are totally encapsulated, making them the safer distribution busbar on the market. Tap off equipped with shutters prevent access to live parts when the functional unit is removed out. Terminal block covers and internal separation up to 4b offer greater protection. 20

21 Standards Compliance Okken... goes beyond the IEC standard Maintenance and modification capability All the electrical installations are operating correctly for the safety of the employees and for the security of equipment. Withdrawable solutions or s on Polyfast units provide continuity of service and safety, even while additional feeders are being added. The modularity allows easy modifying or upgrading of the switchboard to adapt to the changing processes and increase performance. The withdrawable s can be disconnected while the equipment is energised, without cutting switchboard supply and in complete operator safety. They have three positions: connected, test and disconnected position; with disconnection of line and load connections in test position. Capability to be installed onsite The different framework associations are adapted to electrical room configurations. The connections can be made from the front or rear, from the top and/or the bottom. The installation is simplified thanks to builtin handling plinth, removable girders and premounted sliding fishplates. Schneider Electric Product inside* Protection of the assembly against environmental conditions Corrosive environments the conductive parts are treated with anticorrosion (IEC 72133): fixed parts with tin (i.e. busbar trunkings), withdrawable parts with nickel (i.e. clamps). Marine and offshore applications marine versions are designed for saline environments and are Det Norsk Veritas (DNV) certified. Seismic areas Okken 2G and 5G versions offer excellent mechanical resistance guaranteeing continuity of electrical supply. 2G is recommended for most sensitive applications. 5G is designed for the most critical applications, such as nuclear power plants. Corrosive atmospheres IP54 degree of protection Seismic zones IP41 and IP54 ratings provide integrity in dusty and/or damp environments. Okken is DEP Shell certified for petrochemical industries. * Using only Schneider Electric devices guarantees compliance with IEC as well as the reliability of installations. 21

22 Standards Compliance Original manufacturer and assembly manufacturer Involvement in assembly testing Standard IEC clearly defines the type of verifications that must be conducted by both organisations involved in final conformity of the solution: the original manufacturer, guaranteeing assembly system design and Mayfield s responsibility for the final conformity of the switchboard. Project specification* Specifier Specifies the needs and constraints for design, installation, operation and upgrading of the complete system. Checks that its requirements have been fully integrated by the assembly manufacturer. Depending on the application, the specifier could be the end user or a design office. Assembly System Tested Assembly Original Manufacturer The organisation that has carried out the original design and the associated verification of an assembly system. They are responsible for the design verifications listed by IEC including many electrical tests. Mayfield Industries is responsible for the completed assembly. Mayfield is responsible for routine verifications on each panel produced, according to the standard. If Mayfield deviate from the instructions of the original manufacturer Mayfield have to carry out design verifications again. * Schneider Electric has developed a specification guide. End User Should ask for a certified LV switchboard. By systematically requesting routine verifications, they ensure that the assembly system used is compliant. 22
