Electrical Safety Model n° 1: single-phase electrical network

Set composed of a network module, an earthing module, and a laminated diagram symbolizing the electrical supply to a house. The network module represents the arrival of current in a house and the connection to the ground; the power supply is at very low safety voltage of 12 V alternating current (SELV). The power socket module has 3 sockets for measuring (using a multimeter) the potential differences between the phase, neutral, and earth of a real 2P+T socket. This set can be combined with electrical safety models 2 and 3 to study the roles of the circuit breaker and the differential in a domestic electrical installation. Safety sockets D. 4 mm. To be completed with safety cords of different colors.
