Last post i already discuss about Earthing system classification.I mention earthing system have a several types such as TT,IT,TN-C,TN-S and TN-C-S.This time i want explain detail about type of earthing systems.

Earthing system is designed followed by electrical system required and the application.It have different earthing system for each electrical application such as consumer power supply,substation,offshore,ships,underground system,generator and over head system.

We must know the suitable earthing types to ensure our system is fully protected and safety.I explains detail about all of five ( 5 ) earthing system types below.I hope it can help to understand about earthing system. read more

This device is important in electrical wiring installation.It is a life guard device to protect from electric shock.Others circuit breaker only can detect the fault from over current and short circuit but cannot detect the current leakage.

That why RCCB is very important.Only this device can detect the current leakage.The current leakage can cause the injury or dead for human and can lead to fire hazard.When design the distribution panel board,please make sure this device include in our planning to install..it for consumer safety and avoid equipment from damage. read more
