Brian - yes, wago do mf when used in conjunction with their connectors and enclosures which Screwfix sell. in my opinion the push-fit ones are better than the lever type because they take up less space
I often use the Hellacon push fit connectors, not sure whether or not they stipulate their enclosure needs to be used to make them MF as Wago do?
um, thats the orange, jelly type connectors isnt it Sen? um, not sure about those, but seem to recall wago state theirs are when the connector is used in conjunction with their boxes. I have been known to use them inside a patress box which provides more room to work with
