My RCD external sockets do precisely that, at least most of the time.

I forgot to say the obvious - make sure you get the active version, as
some Web sites don't clarify which they are selling. It also comes in
a double version, which I have. I had a cheaper equivalent once, but
it died - but all reports, this one is pretty durable.

As it says, the feature is also useful for garden machinery.
