Re: A possible solution
A place I worked in the early 80s had the entire comms rack running from a single 13A socket - the building had a huge alternator and generator waiting to kick in should the mains fail.
I was squatting by the comms rack looking for a problem (oh all right - it was a hot day and I wanted to be in the cool) when the whole rack went dark.
Brown trousers time - there are going to be a hundred angry calls from users.
I look round to see that the cleaner has unplugged it all from the mains to plug in the vacuum.
Next to the socket they had purloined, actually in the same faceplate, was another, fully functional, and EMPTY socket.
We moved the disk racking two inches to the left so as to ward off a repeat.
