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
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.
