Abstract

An electronic circuit is composed of two resistances of variable values, I.e. between 330 and 68 kilo-ohms and a light emitting diode, while the terminal points (4,5,6) of the circuit must be connected respectively to the phase, neutral and earth. The electric circuit is connected to a tool with a residual current circuit breaker and the test result is indicated by lighting of a colored light emitting diode : Independent claims are included for tools including electronic circuits, for an electrical safety and residual current test tool, for a plug with earthing/test connection to an appliance, for cables and extensions with permanent earthing control and for electrical safety/earthing test accessory for hand-held appliances.
