Whether computers, phones or large production machines, electrical appliances are indispensable in everyday work and need to work so flawlessly. Whether computers, phones and kettle or large production machines, the electric current is indispensable in everyday work. All electrical equipment and facilities must therefore always reliably work and may have no damage, which represent a danger for the user.

A merger of several electrical equipment forms an electrical system electrical installations and electrical equipment.
The main feature of electrical systems and operating equipment is the use of electric energy. This is distributed through the devices, transformed, consumed, taken and stored. Resources according to GUV-V A3 are also subject to protection and aid, the electrical safety requirements. Also telecommunications and information technology is one of the electrical equipment. The GUV-V A3 accident prevention regulation distinguishes between mobile and stationary electrical apparatus, as well as between stationary and non-stationary systems. More detailed information about the types of electrical equipment and installations the following further explains. Person – electrician enabled electro-technically instructed person electrical vocational training, expertise and experience in the field of electrical machinery and equipment are the most important prerequisites to empower a person carry out tests. The experience of the person should include Assembly, commissioning, maintenance and the use of electrical devices.
Also all relevant rules and regulations must be known so that potential hazards are identified can. All this knowledge is available, it is a competent person, more precisely to a qualified electrician. She is entitled to the testing of electrical equipment and installations. In practice, it is often to electricians, electrician or electrical engineers. In-house staff can be electrically instructed in training.
