The protective isolation transformer

Principle

When a separating transformer is used, there is no conductive connection between the primary circuit ("ring main") and the secondary circuit ("consumer circuit"). There is no voltage between the consumer circuit and earth. When a person touches a lead in the consumer circuit that is carrying current but is not insulated, he is protected by this transformer (protective separating transformer).

Benefits

• No additional cable connections between the building blocks needed - clear arragned and quick setup
• Contact saftey due to puzzle blocks system
• Corrosion-free gold plated contacts
• Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside

Tasks

How can a dangerous flow of current from an L-lead through the human body to earth be prevented?
