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

I was afraid elf 'n safety had got rid of them, but Google shows they are still around. Google for SafeBloc (no 'k'). There's another unrelated product with the same name, so you'll need to filter those out! -- Use the BIG mirror service in the UK: http://www.mirrorservice.org |

Steve Walker has brought this to us :
Mmmm, I know what you mean - I've seen them used in electrical retailers. Personally I always end up using insulated test leads with mini croc clips when I want to try a batch of components, but it's a bit fiddly and I wouldn't mind a "safe block" for the workbench (old trembly hands nowadays....) The 'safe' part is that before you can get to the croc clips - opening the cover disconnects the supply. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

I regularly use a couple of them. I've heard of some of them nicknamed "LEN" blocks, since the terminal clips are labelled "L","E" and "N". -- Frank Erskine |

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. :) -- |
