When were ceiling rose junction boxes invented? They appear to be post WW2 as I have been unable to find any that are older. The ceiling roses I have from the 1920s and 30s are either purely mechanical or have terminals just for live and neutral for the light fitting. Were ceiling rose junction boxes intended as a cost saving feature when constructing houses?
Once I found the 1969 version, and there was no listing against the standard it "replaces", I didn't look any further, as I took it that previous standards would not have been similar due to a major change in scope or principles or something like that.
