This LearnElectrics video is part 4 of our mini-series on protective devices where we take a simplified look at the different types of RCD.
We will look at the different types of tests that we must carry out, the mandatory tests and also those tests that are optional and not a requirement of BS7671 Wiring Regulations.
The first question that always pops up is - what is an RCD? So we will take a simplified view of RCD devices, and how they work, before moving on to the different types, why we have different types and what tests must be carried out and recorded.
And the second question is often – do I need a new meter?
This is video number 194 and to view all our videos type in LearnElectrics all one word into the YouTube search bar.
