* Protection against electric shocks:

Class I


mentions that basic isolation application is not sufficient to protect against electrical shock, so that the devices that are under additional protection that connects the stable facility to the grounding conductor to prevent the device’s conductor parts to be under tension in case if this isolation is not working. Grounding is necessary.  



Class II



shows the luminaire in which the isolation is not only provided with basic isolation, but the protection against electrical shock is increased with extra isolation materials.



Class III;


shows the devices of which protection against electric shock is achieved with safety extra low voltage, (SELV) and in which very low voltage is supplied.
