With this kit one can easily determine whether a wire is live or not. This kit can be used to detect wiring within walls or breaks 
in cabling.  A flashing LED shows whether a current is detected, while the speed at which the LED flashes indicates how 
close one is to the wiring. For those wanting an audible signal, space is provided on the print for connecting a buzzer type 
SV4/12. The small PCB has been specially designed to be incorporated into the separately available casing type G407.
