Default Re: Another unusual plug and some other questions

re Brigham, it looks as though "Lights" was indeed intentional and not a typo.

When looking for items to scan I came across 3 or 4 further references in parts of the catalogue I had never got around to reading. It appears that "Light" and Ampere" were used interchangeably, insofar as a type of switch that is described as being rated at so many "lights" in one part, is rated as the same number of Amperes in another part. I guess that the terminology was still developing: for example, Bus bars are referred to as "Omnibus bars".

There is a one-page description of a concentric domestic wiring system (which does use "lights"), but no pictures, and you are referred to a seperate leaflet for details which I don't have. My catalogue is actually a set of individual catalogues that have been bound into a single book, and not all volumes of the set are present.
