Fault in Electrical circuits

There's no guarantee that every wiring you done isn't perfect. but when you test, something happen to the wiring that might bring fault to your wiring. So lets find out some faults.

1) Open Circuit (Incomplete Circuit)

 After you done some wiring but eventually your wiring doesn't power any lights or fans. That fault is called 'open circuit'. This fault happen when the wiring is loose contact or cable might be disconnect. To fix this,you need to tighten the wire and connect back the wire.


2) Short Circuit ( Hot or Live wire have contact with Neutral wire)

This kind of fault is very common happen in our house. This fault happen when live or hot wire have contact with neutral wire. This fault can be happen maybe your house wiring too old and loose contact or can be interrupt by mechanical interference like rat in your house have bite with your house wiring and end up with rotten mice.

3)Earth Leakage ( When Earth wire contact with Live or Neutral wire)

Earth is so important in electrical wiring that keeps every electrical device and house keeps save. If this earth failed to keep safe, then earth leakage fault happen. this fault happen when earth have contact with live or neutral wire and over current will be produce due to this fault. this over current will be prevent by RCCB (Residual Current Circuit Breaker) that will trip immediately when the current reaches between 30mA-300mA due to type of RCCB.
