Earth Leakage Current

What Is Earth Leakage Current?

In the context of an RCD tripping, earth leakage current is the electrical current that, because of circuit imperfections, flows to earth directly.

 

If a circuit was perfect their would be no 'earth leakage', i.e. electrical current 'leaking' to earth.

 

  • A perfect electrical circuit has no earth leakage current.
  •  

  • An electrical circuit that is slightly less than perfect has a slight earth leakage current.
  •  

  • An electrical circuit that is a lot less than perfect has a higher earth leakage current.
  •  

  • An electrical circuit with a problem has a high earth leakage current.

An RCD monitors earth leakage current – if an electrical appliance (electrical circuit) has a problem, the RCD trips.
