What is Class I equipment

Type I equipment refers to equipment that is basically insulated, but also equipped with a connection device that allows conductive parts that carry dangerous voltages if the basic insulation fails to be connected to the protective grounding conductor in the building wiring.

In addition, Class II equipment refers to the protection against electric shock not only rely on the basic insulation, but also to take additional safety measures (such as the use of double insulation or reinforced insulation equipment), this type of equipment does not rely on the protection of the ground, nor the installation conditions of the protection measures.
