  • The electrics are tripping even when the appliances are all disconnected. The cliant was telling that the situation gradually got worst. First ..it was tripping once per month.. then weekly ..and daily ..hourly ..and now it barly holds on and tripping out the electric circuit. Now.. the question is how to rectify this. First isolate the circuit by removing the Load ( example.. switch off all the lights connected.. and unplug all the appliances) IF the circuit breaker trips.. then..it is highly likely ..that the problem is faulty cables or connections. Only registered electrical engineer can perform the testing to find out whats wrong. First.. Insulation test between L – E , N-E, to find any earth leaks ..if you get low reading ( Example: 1 – ohm ) that means there is a prob lem with the cables or joints which need further investigation , repair or rewiring.
