*Class I equipment includes not only insulation of live parts but an earth connection via the flexible cord and power outlet to accessible conductive parts. The accessible parts will not become live if the basic insulation fails. However the disadvantage of Class 1 equipment is that an electric shock can still occur if a person forms a connection between live and earthed components.

*Class II equipment does not have an earth connection but relies on double or reinforced insulation for protection.
