Is it ok to control an outdoor double socket with a programmable switched timer - the type usually used for lighting? The sockets are for a pond pump and filter which use c 35w while the timer switch wd be mounted in a shed and on a 6a mcb. My sparky didn’t sound concerned - he basically said buy in the stuff and he’ll come and fit it. The pump is well within the max load of the switch but my understanding wavers when I see that the min varies on the lighting used. And I can’t find any web evidence of this kind of set up. So any thoughts gratefully received.
