Protection of persons
Earth and differential principle
Role of insulators in an electrical installation
Influence of soil type
Description
Complementary set to the electrical safety 1 model which allows to visualize the connection of an electrical appliance in a domestic installation and to explain the role of the differential by simulating an electrical fault (washing machine module casing).
The modules are supplied with 12 V alternating current from the earthed socket.
The floors are interchangeable and can be earthed.
The dummy can be connected to the washing machine housing to cause a current leakage in the circuit: an LED lights up on the dummy and the differential trips as soon as the current drops by more than 30 mA.
To be completed with safety cords of different colours.
Composition
- 1 differential module 30 mA. Dim.: 120 x 160 x 90 mm.
- 1 washing machine module. Dim. 90 x 135 x 35 mm.
- 1 dummy. Dim. : 205 x 90 mm.
- 1 set of 3 interchangeable insulating and conductive floors. Size : 100 x 50 mm.
