Again refer to the data sheet and use not only a ratchet tool but one with the die form recommended by the terminal manufacturer. They vary so widely in quality and construction that some are no good for 10A while others are probably OK for 50A. I don't think one can apply a universal rating to butt crimps. I would only use a crimp terminal on a solid conductor if the manufacturer specifically approves it in the data sheet. Some types of crimps are unsuitable for solid conductors, including some of the generic ones that wholesalers like to stock. I would therefore recommend the 4.0 mm size or either of the lever types for jointing an RFC. ![]() The popular push-wire type 773 2.5mm² size as mentioned above is limited to 24A which may be less than the cable in some situations. ![]() ![]() Wago lever connectors type 221 & 222 are suitable for all types of conductors, stranded and solid, and rated up to 32A. One leg will be connected through the socket, the other needs some suitable connectors. They may still work with a #4 screw if the connecting metal isn’t destroyed drilling them.The OP wants to extend the ring. delivered I wish they had a clip on screw base (and such may exist somewhere on the internet, but as yet I have not been able to find it), but until I get a 3D printer, I figure I can sacrifice one on each end and drill through the probe hole for a #4 or #6 screw. These joinable singles are 20 for $16.99 Cdn. As well, the 20 port jobs with screw mounts I mentioned earlier did not appear available until January when I last looked, and the price about doubles (correction, on closer review of the shopping care, close to triple) with exchange, duty, and all sorts of added shipping fees to Canada, making them more expensive than the terminal strips. I got these mainly to check them out as a better solution than big bulky terminal strips, plus the effort of soldering spade lugs for the 5 to 7 wires I am running to each of the MP5 switch machines on the B&H. The bond is incredibly strong - it takes a fair bit of finger effort to pull them apart. Shown here as single (right), part way joined (left) and fully joined (center). Single units that have a very strong slide together design that forms a very solid join. Ross shows you how to use the Wago connector - these easy push in wire connectors are super easy Watch the vi. They are glued to the bottom of my layout with E6000 Glue. These easy wire connectors make life simple. The maximum surrounding air temperature is 85. Sorry, I do no have any underside photos of the connectors. Wago connector nuts are rated to a nominal voltage of 450V, a surge voltage of 4kV, and a current of 41 Amps. From the double 14 gauge buss to my 22 gauge track feeders, they are gripped tight. The flexibility of these Wagos is impressive. I give each wire a pretty good tug to make sure they are gripped well, and did not have any pull out. ![]() I was originally going to slide the connectors on 1 single through wire and just strip away insulation where needed, but the insulation proved to be to thick to fit through the Wago. My buss wires are 2 separate wires, inserted from each end. If that's a correct assumption, have you had any trouble clamping two main buss wire sized wires under one lever? A photo of the clear underside would be very useful. Not a solid wire that has had it's insulation exposed mid-run? In addition, a large accessories portfolio is available, making WAGO's 221 Series Splicing Connectors great. They are available in various designs and variants. I'm curious, I'm assuming your through route are two distinct wires, clamped in common. As tool-free, lever-actuated connectors, WAGO's 221 Series Splicing Connectors easily, quickly and safely connect solid, stranded and fine-stranded conductors ranging from 2410 AWG.
