Terminal block jumpers, something like these **LINK** ?

1+ for the Wago connectors, I hardly use the old blocks now

John, barrier strips are teh actuial choc blocks, Duncan wants the metal strips that can be screwed into one or more to electrically join them together

Duncan,

Regards, Bear..

problem with WAGOs is you can only use them once – choice bloc as many times as you like.

Wago connectors of the old and new types can be used many times. they are not the same as the push in and that's it versions. Please do not castigate what you do not understand.

I'd use wire myself too. I just found these though, never seen them before. Jumper bars.

RS do an item called a commoning block which I find very useful.

is on example. They do various ones. They are however not cheap.

I find the "wago" approval of things like installing 13 amp spurs of a ring main odd John as they haven't been around all that long. The usual round junction boxes have. They started specifying things like earth bonding and sleeving the earth wire in sockets etc in the 70's all based on problems that have happened rather than theory. Also providing an earth wire termination in plastic boxes. Maybe thing have moved on to catering for electricians who can't wire up correctly. Personally I don't mind working on live mains at home providing I have my neon screw driver handy in case some idiot has crossed live and neutral. They are essential when twin switches are on a single light.

The stray wires from stranded wire is a problem on screw terminals used in a number of things. The natural tendency is to twist the strands together and then push them in and tighten down the screw. Fine but if some one checks the screw tightness later they will find that they have loosened off. If the strands aren't twisted the screws stay tight. It's worse on the better quality barrier strips where the screws press a spring leaf onto the wire.

There are crimps available to hold the strands together. Solder can be used with some care but only a sort of dab on the end usually done with a solder pot not an iron. If the whole bare end is done it needs some care in things like plugs as it can flow well back up the insulation and is likely to leave stress when the cable is fitted. There is a stress point at the end of the solder anyway as John pointed out. A lot depends one where it's used and vibration. Most things these days come with plugs on often moulded but I have come across leads that have been prepared for a plug by careful tinning. Always very neatly done. Even the strands have been nice and tightly bunched up in the solder. Not the easiest of things to do with a soldering iron.

The nice thing about Wago and other types of spring terminals is that they never loosen, I think they are intended for bare wire ends but some people use bootlace ferrules, these can present other problems as they can prevent the full insertion into the connector. I apply a light twist to wires intended for the Wago type terminal just to combat the stray strand problem. Although a terminal screwdriver can be used for insertion and release, the Wago tool does make life simpler as it is short and cranked so that you get better access to the hole for the wire to go in, access for normal probes for testing is not very good but adaptors are available to plug into the holes used for jumpering purposes. I usually cut the ends back of cables that have been helpfully tinned by the supplier to get bare wire. Connectors where the screw bares directly on the cable have a tendency to cut the wire if overtightened and as mentioned above they lose grip in time.
