Outdoor area - Completely on RCD protection?

Good day!

I have a question, preferably for an electrician. I now have my own fuse box in a small outbuilding. There is a circuit for the entire outdoor area connected to it on its own fuse (B16) and then the outbuilding on several others.

I wanted to ask if it makes sense to connect the outdoor area to an RCD, in case water gets into a lamp/socket or something, or if a child sprays water around.

Is that sensible or is it better not to do that?

Thank you very much!

Hi!

Of course, it can make sense to connect the outdoor area to an RCD. But it can also backfire. For example, if you connect a large appliance to an RCD, it will trip because the leakage current is simply too high; a normal fuse doesn’t bother it, but the RCD does.

But in principle, it is a sensible thing to do; I have done it at our place as well. The garden and yard are completely protected by an RCD.

Best regards
