IEC 60364
IEC 60364 ''Electrical Installations for Buildings'' is the International Electrotechnical Commission (IEC)'s international standard on ''electrical installations of buildings''. This standard is an attempt to harmonize national wiring standards in an IEC standard and is published in the European Union by CENELEC as "HD 60364". The latest versions of many European wiring regulations (e.g., BS 7671 in the UK) follow the section structure of IEC 60364 very closely, but contain additional language to cater for historic national practice and to simplify field use and determination of compliance by electricians and inspectors. National codes and site guides are meant to attain the common objectives of IEC 60364, and provide rules in a form that allows for guidance of persons installing and inspecting electrical systems. The standard has several parts: * Part 1: Fundamental principles, assessment of general characteristics, definitions * Part 4: Protection for safety ** Section 41: Pro ...

National Electrical Safety Code
The National Electrical Safety Code (NESC) or ANSI Standard C2 is a United States standard of the safe installation, operation, and maintenance of electric power and communication utility systems including power substations, power and communication overhead lines, and power and communication underground lines. It is published by the Institute of Electrical and Electronics Engineers (IEEE). "National Electrical Safety Code" and "NESC" are registered trademarks of the IEEE. The NESC should not be confused with the National Electrical Code (NEC) published by the National Fire Protection Association (NFPA). The NEC is used for residential, commercial, and industrial building wiring. General Access to the NESC The NESC is written as a voluntary standard. It is typically adopted as law by individual states or other governmental authorities. To determine the legal status of the NESC, the state public service commission, public utility commission, or other governmental authority should be c ...

Canadian Electrical Code
The Canadian Electrical Code, CE Code, or CSA C22.1 is a standard published by the Canadian Standards Association pertaining to the installation and maintenance of electrical equipment in Canada. The first edition of the Canadian Electrical Code was published in 1927. The current (25th) edition was published in April of 2021. Code revisions are now scheduled on a three-year cycle. The Code is produced by a large body of volunteers from industry and various levels of government. The Code uses a prescriptive model, outlining in detail the wiring methods that are acceptable. In the current edition, the Code recognizes that other methods can be used to assure safe installations, but these methods must be acceptable to the authority enforcing the Code in a particular jurisdiction. The Canadian Electrical Code serves as the basis for wiring regulations across Canada. Generally, legislation adopts the Code by reference, usually with a schedule of changes that amend the Code for local c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEEE C2
American National Standard C2 is the American National Standards Institute (ANSI) standard for the National Electrical Safety Code (NESC), published by the Institute of Electrical and Electronics Engineers (IEEE). The NESC is a most important document for safeguarding persons against electrical hazards during the installation, operation and maintenance of electric supply and communication lines. More essentially, it includes general updates and critical revisions that directly contact the power utility industry. Adopted by law by the majority of states and Public Service Commissions across the US, the NESC is a performance code considered to be the authoritative source on good electrical engineering practice.

PSE Law
The is the law that governs electrical appliance safety in Japan. PSE stands for Product Safety Electrical Appliance & Material. The formal name is . The most recent revision comes April 1, 2001. The PSE symbol can be found on appliances that are approved for use in Japan. DENAN is a mandatory national law administered by Japan's Ministry of Economy, Trade and Industry (METI), which was formerly called the Electrical Appliance and Material Control Law (“DENTORI”). For electrical appliances such as DC Power Supplies exported to Japan, the DENAN “DENAN symbol” approval is required. AC/DC power supplies are considered a "Category A" product with means they are specified products and require a diamond PSE Mark for use in Japan. These specified electrical appliances are either required to undergo third-party conformity assessment, and obtain their certificate, or obtain “the equivalent of a certificate” through the manufacturers of the specified electrical appliances ...

Electrical Safety
Electrical safety testing is essential to make sure electrical products and electrical installations are safe. To meet this goal, governments and various technical bodies have developed electrical safety standards. All countries have their own electrical safety standards that must be complied with. To meet to these standards, electrical products and electrical installations must pass electrical safety tests. Some types of electrical safety tests include: *dielectric withstand test (also called a hipot test) *insulation resistance test (IR test) *earth continuity test *leakage current test Electrical safety tests are described in IEC 60335, IEC 61010, AS/NZS 3000, NFPA 70, BS 7671, and other national and international standards.\ Electrical Safety tests Dielectric voltage withstand test A dielectric voltage withstand test (also known as a hipot test) is done by applying a voltage higher than operating voltage to the device or installation under test.

Electrical Wiring
Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and electrical cable, cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist.
