I know there have been threads about this before but I'm using a mobile and struggling to find it.
Choc blocks are a pain in the butt, what else do you use to join bare data wires?

These Wago connectors are excellent -provided they are not somewhere they will get wet! I don't like having connectors as such, so tend to go for heat/glue shrink crimped connectors if I am going for permanence. For testing hook ups - Wago are nearly unbeatable and much faster than choc-block.

There are of course many ways to join a wire, depending upon the wire and it's purpose. As you mention choc blocks <insert spitting emoji> and data wires i guess you might be wiring in some electronics with NMEA 0183 connections. Choc blocks aren't good on a boat and these wires are probably the worst place to use them. Solder and heat shrink is sometimes used, but i'm not a fan of that method, usually. Solder can easily wick up the wires, hard spots are easy to create, resulting in broken wires within the insulation or heat shrink, a real pain to fault find.

Best way by far is to use Wago connectors. 221 series are nice for really small stuff, like NMEA wires on chart plotters etc. taking wires 0.14mm² to 4 mm² . 222 series can also cope with NMEA wires too and will take anything from 0.08 mm² – 4 mm² stranded cable.

Both can be stuck together in groups and stuck to bulkheads, enclosures etc, quick setting Araldite or similar works well. You can also put more than one wire in each hole, particularly when using stranded cable, as we do.

Be sure to buy from a reputable source so you get genuine Wagos, not Chinese clones.

Caution, you are in danger of a tongue lashing for uttering the W--o word as I found out in this parish some 10 days ago. Apparently not the poodles privates but the worst thing known to man.

I am afraid for some things I like Wagos. If you solder small power connections ( eg mast light wires inside cabin headlining) or data wires you inevitably lose some length if you have cut to to alter connections, with Wagos you just unclip. Wagos often much better than choc-blocs or crimped bullet or spade connectors. There are places for soldered and heatshrinked connections, but for many jobs (and for quick fixes) Wagos are excellent.

Choc blocks are ok used with bootlace terminations and with the steel screws replaced with sinless ones.

Sorry, but they are not, the terminal block will still be steel and will rust in a damp environment. If you have to go the the trouble of crimping bootlace ferules to the wires, you may as well use ring terminals and proper busbars. But, for the small data wires being discussed here, i still think Wagos take some beating.

There are, as i said, many ways to join a wire. There are applications where one way will be the dogs nuts, but in another application it will be disaster. I often use crimp terminals, usually with shrink tube for additional support, but they are a bit clumsy for really small wires. 221 or 222 series Wagos are a good solution. But, i wouldn't be using them for the bilge pumps, where the only way it fully waterproof connections.

Gluing them together sounds a bit hit and miss. They all seem to have small slots on the sides so is there some device they can all be clipped in to?

Thanks Paul, very helpful. Best supplier in/around the Ipswich area?

They look like they might clip together, but they don't, disappointingly. Gluing them is easy enough, stick them together on the table, (bit of tin foil or similar so you don't stick them to the table), then stick them where you want them, with a bit of duct tape to hold them until the epoxy dries. Toolstation does an Araldite clone, which dries in a few minutes.

Other than that, the 222 series can be fitted to these http://uk.farnell.com/wago/222-500/mounting-carrier-splicing-conn/dp/2643509
