Fundamental rule of protection
Protection against direct contact
Measures of protection against direct contact
Additional measure of protection against direct contact
Protection against indirect contact
Measures of protection: two levels
Automatic disconnection for TT system
Automatic disconnection for TN systems
Automatic disconnection on a second fault in an IT system
Measures of protection against direct or indirect contact without automatic disconnection of supply
Protection of goods in case of insulation fault
