Summary
The aim of this subject is to acquaint students of FEI 1st class with basic safety rules and regualtions for activity on electric devices. After their knowledge verification, they will become instructed persons in terms of provision §4 Decree 50/1978 Coll. and they will be able to work on electric devices in FEECS laboratories.
Learning Outcomes of the Course Unit
Students will learn the basic safety rules and regulations necessary for operation of electrical installations so that they pass the regulation and requirements for measurement in Faculty of Electrical Engineering and Computer Science laboratories.
