We attached a relay to the socket to switch the vacuum cleaner and the drill on and off.
Someone commented on our post:
Sometimes the sockets have those protective mechanisms, and sometimes they don’t.
For a standard domestic socket model, it’s less likely than in industrial socket models.
There are models of socket with in-built trip-switches for each socket, but from picture 3, you don’t seem to have those there.
It might be worth checking the overall power on each ring main that you are using.
If the overall draw is more than is available, then that might be a reason for the intermittency. - BillySmith@mastodon.social
