HOW RCDs WORK

Have you ever wondered just how an RCD works?
How does it detect those minute differences in current that can mean the difference between a harmful electric shock and walking away from an electrical fault unscathed.
And what exactly is a residual current?
Do RCDs offer fault protection?
And what is additional protection?
All this and more will be unveiled in this short video into RCD basics.
We have kept it simple and to the point.
Here are the key factors that make an RCD work and how it keeps you safe.

Another excellent instructional video from Learn Electrics - thanks.
Where do you get the slide images from ?
They are so clear and explain exactly how the RCD works - I've not seen anything so comprehensive and at the same time concise.
Did you draw them yourselves ?
