The risk when working with electricity

Why do many people use the services of electricity while performing even simple repairs or replacement of components of electrical installations? This question can be answered in a very simple way - a lot of people afraid of any contact with the flow, because it can be extremely dangerous not only for health, but also for human life. Commonly known cases in which the electrician while performing their work was seriously injured and even died as a result of contact with electricity. On the other hand, many electricians have daily contact with electrical installations retains fewer and fewer safety work and then can easily lead to tragedy.


Learning electrician

Technical profile electrician certainly is much less likely to be selected than other specialties, such as construction. This is because the vocational subjects, where young people learn from this direction are much more difficult, since they concern the often incomprehensible for youth affairs physical and mechanical properties. However, anyone interested in this field and who want to learn a profession electrician certainly can handle, if studied systematically. Completion of such a school is crowned with theoretical and practical exam, which entitles you to perform electrical services, such as installation and repair of the system.


Electrical code - definition

An electrical code is a set of regulations for electrical wiring. The intention of an electrical code is to provide standards to ensure electrical wiring systems that are safe and unlikely to produce either electric shock or fires. Ways in which electrical codes ensure safety include ways to prevent (or mitigate) short circuits, ground faults, and overheating from inadequate current-carrying capacity (ampacity). Appropriately rated fuses or circuit breakers are used to interrupt a circuit loop whose ampacity is exceeded to avoid overheating of wires or other fixtures. Electrical codes are usually devised by national or international technical organizations, and adopted as law to make them enforceable. Electrical codes differ based on geographic area. See the following:

DIN VDE (German Institute for Standardization) published by DIN-Norms is used in Germany
National Electrical Code has been adopted for electrical wiring in the United States and for Mexico, Costa Rica, Venezuela and Colombia
IEC 60364 is used as a basis for electrical codes in many European countries
Canadian Electrical Code published by the CSA is used in Canada (see Electrical wiring in North America).
British Standard BS 7671 is the set of regulations for electrical wiring in the United Kingdom.
Australian/New Zealand Standard AS/NZS 3000:2007 Wiring Rules is used in Australia and New Zealand.
NF C 15-100 (fr) is used for low voltage installations in France
RGIE (fr) (Réglement Général sur les Installations Électriques) is used for installations in Belgium.
AREI (nl) (Algemeen Reglement Elektrische Installaties) is used for installations in Flanders, Belgium.
