I'm after what we used to call a "safe block" - although I think thatwas a trade name.It's a quick way of applying power to something that only has barewires on a trailing lead.A safe block is 3 spring loaded clamps in a small box with a hingedlid, and attached to a trailing mains lead with plug. (but no power isapplied until you close the box lid, so no exposed live terminals).Anyway, it would be useful to apply power to pumps and valves in mycentral heating to make sure they're good, before the fixed wiring isdone.Anyone name a reasonably priced supplier, or products that fulfill thesame function but go by a different name?

I've got one upstairs but Google gives several Ebay choices or:

They were deemed 'less safe' that the Safebloc as they only had a single phase disconnect and I suspect that was the main reason they died a death in the catalogues a decade or so ago.

It's not a huge problem if it's a permanent installation on a test bench but move it into the field and a phase/neutral reversal could leave a piece of equipment live - if you were stupid enough to go inside said equipment relying on the keynector for isolation. :)
