IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems.
An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not. The later requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or ...
Electrical installations. 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. [ 1]

Electrical installations. NICEIC is one of several organisations which assesses the competence of businesses undertaking electrical work in the UK. NICEIC is one of several providers given Government approval to offer Competent Person Schemes in England and Wales to oversee electrical work within the scope of Part P of the Building Regulations.
The electrical safety develops with the technical progress. In 1989 OSHA [1] promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. [2] In 1994 were established Electrical ...
