Currently, in addition to placing the appropriate printing on trucks, which move electricians, it is also popular free opportunity to advertise their services by setting up a website which deals with the activities of electricity.Then people seeking advice in this regard natrafiwszy on such a site would be happy to benefit from the services of a particular electrician.
Wiring safety codes are intended to protect people and property from electrical shock and fire hazards.
Since 1897 the US National Fire Protection Association, a private non-profit association formed by insurance companies, has published the National Electrical Code (NEC).
States, counties or cities often include the NEC in their local building codes by reference along with local differences.The NEC is modified every three years.
It is a consensus code considering suggestions from interested parties.
DIN VDE 0100 is the German wiring regulations document harmonised with IEC 60364. In the United Kingdom, wiring installations are regulated by the Institution of Engineering and Technology Requirements for Electrical Installations: IEE Wiring Regulations, BS 7671: 2008, which are harmonised with IEC 60364.
The standard is mandatory in both New Zealand and Australia; therefore, all electrical work covered by the standard must comply. In European countries, an attempt has been made to harmonise national wiring standards in an IEC standard, IEC 60364 Electrical Installations for Buildings.
Hence national standards follow an identical system of sections and chapters.
However, this standard is not written in such language that it can readily be adopted as a national wiring code.
Neither is it designed for field use by electrical tradesmen and inspectors for testing compliance with national wiring standards.By contrast, national codes, such as the NEC or CSA C22.1, generally exemplify the common objectives of IEC 60364, but provide specific rules in a form that allows for guidance of those installing and inspecting electrical systems. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission. In North America, the American Wire Gauge standard for wire sizes is used.

Building wiring is the electrical wiring and associated devices such as switches, meters and light fittings used in buildings or other structures.
Electrical wiring uses insulated conductors. Wires and cables are rated by the circuit voltage, temperature and environmental conditions (moisture, sunlight, oil, chemicals) in which they can be used, and their maximum current.
Wiring safety codes vary by country, and the International Electrotechnical Commission (IEC) is attempting to standardise wiring amongst member countries.Colour codes are used to distinguish line, neutral and earth (ground) wires. Źródło: https://en.wikipedia.org/wiki/Electrical_wiring.
