Central Heating Trips RCD

This web page provides information that helps you to investigate the central heating tripping an RCD.


What Causes An RCD To Trip?

An RCD trips because the current flowing into an electrical circuit is not the same as the current flowing out of an electrical circuit.

 

A difference between the current flowing in and the current flowing out of an electrical circuit means the circuit has a serious problem.

 

If the ‘electrical circuit’ is your central heating, an RCD tripping means your central heating has a serious problem.

 

The RCD is tripping for a reason – do not ignore the problem.
