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] |
Canadian Standards Association
The CSA Group (formerly the Canadian Standards Association; CSA) is a standards organization which develops standards in 57 areas. CSA publishes standards in print and electronic form, and provides training and advisory services. CSA is composed of representatives from industry, government, and consumer groups. CSA began as the Canadian Engineering Standards Association (CESA) in 1919, federally chartered to create standards. During World War I, lack of interoperability between technical resources led to the formation of a standards committee. CSA is accredited by the Standards Council of Canada, a crown corporation which promotes voluntary standardization in Canada. This accreditation verifies that CSA is competent to carry out standards development and certification functions, and is based on internationally recognised criteria and procedures. The CSA registered mark shows that a product has been independently tested and certified to meet recognized standards for safety or pe ...

National Electrical Code
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association. Despite the use of the term "national", it is not a Law of the United States, federal law. It is typically adopted by U.S. state, states and municipalities in an effort to standardize their enforcement of safe electrical practices. In some cases, the NEC is amended, altered and may even be rejected in lieu of regional regulations as voted on by local governing bodies. The "authority having jurisdiction" inspects for compliance with these standards. The NEC should not be confused with the National Electrical Safety Code (NESC) published by the Institute of Electrical and Electronics Engineers (IEEE). The NESC is used for electric power and communication utility systems including overh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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. See also * IEC 60364 * 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 subst ...

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 ...

Slash Rating
The slash rating, under the United States National Electrical Code, is given to circuit interrupt hardware and specifies a maximum line-to-ground voltage rating in combination with a maximum line-to-line voltage rating. One common application would be for a three-phase Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral ... electrical loads. For example a 120/240 V rating can disqualify a circuit breaker for use with a delta system load that would otherwise work with a wye system load.

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.
