(57) Abstract: The invention is adevice that provides asmart accurate fault discrimination for every specific load and isolate it alone 
without affecting other loads that are in the same circuit of the faulty load,so it assure the continuity of electric power for other loads.  
The device is operable to beconnected to asocket, wherein the device comprises two relays (relay A, relay B), two lamps (20, 26), an 
oalarmsiren (21), twocopper connectionjoints (3, 4), wherein each of the first relay (relay A) and the second relay (relay B) comprises 
a set of normally closed contacts (1, 9), aset of normally open contacts (6, 11) and acoil, the normally closed contacts of the two relays 
-being arranged in series in the life wire of the device for interrupting the current to the socket and the load in case afault is detected.  
OThe device furthermore helps the user for making fast maintenance for the fault by alerting the user for the position of the faulty load 
Sat this instant with sound and light, so the user can remove the faulty load safely. Also, the application provides an easy maintenance
