I've got an extension lead coming off of a socket that powers a washing machine and a dryer. Sometimes, possibly when they're both on at the same time, the power to the extension goes off. What's weird is that a few minutes later the power comes back again, so nothing's tripped. This socket lives on a spur that comes directly off of the main fuse board. Everything is fine when plugged into a different socket.
Any ideas what's up? Thanks
