WotEver Posted October 14, 2019 Report Share Posted October 14, 2019 If Wagos were to be used then I believe they’re intended for use with solid cable are they not? In which case stranded would require a ferrule. Link to comment Share on other sites More sharing options...

In which case stranded would require a ferrule. Wago connectors are allowed under the RCD (ISO 10133 Small craft — Electrical systems — Extra-low-voltage D.C. installations) 10.4 Screw-clamp or screwless terminal blocks shall conform to IEC 60947-7-1. Other terminals shall be of the ring or self-locking captive-spade type, not dependent on screw or nut tightness alone for retention on the stud or screw.An exception is that friction-type connectors may be used in circuits not exceeding 20 A if the connection does not separate when subjected to a force of 20 N.

WotEver Posted October 14, 2019 Report Share Posted October 14, 2019 (edited) I’m unsure of the meaning of that Reg. Firstly: “Screw-clamp or screwless terminal blocks shall conform to IEC 60947-7-1” Standard Wago connectors with the little flip-up levers like the 221 don’t conform to that spec as far as I’m aware. They make connectors that do but I don’t believe they’re the type we’re discussing. Secondly: “Other terminals shall be of the ring or self-locking captive-spade type, not dependent on screw or nut tightness alone for retention on the stud or screw.” What do they mean by ‘others terminals’? Do they mean connectors which don’t conform to 60947-7-1? If so, what’s the purpose of the first paragraph? I’m confused. Doesn’t take much.

The Wago connectors I have used are 'push-in' types where the 'spring' lifts as you push the wire in and then traps it so it cannot be pulled out.

You need to cover them with clear heat-shrink. Link to comment Share on other sites More sharing options...

I don't know - The company I worked for was in the same 'group' as Wago so I picked up 'a few' of their bits and pieces before I retired (15 years ago - seems like just yesterday) Link to comment Share on other sites More sharing options...

None of the 221 type state that, so I don’t believe they do. This still doesn’t address the meaning of that RCD reg where they refer to ‘other types’. I find that reg ambiguous.

I couldn't find that number but Lloyds and a few others accept them for shipping and they are for solid, multi and fine strand cables Link to comment Share on other sites More sharing options...

You put matching collets on each end of a cable and mark the circuit diagram (which if you haven't got one can be produced as You grace and identify the cables) with each cables unique code.

Dymo / Brady Yes, they look good. I actually labelled up some cables the other day using a brother p-touch label printer, and low tech sellotape, but your solution looks better.
