Default Re: Another unusual plug and some other questions

I'm wondering about the lights / amps thing now. Certainly a rating in lights has been used for various pieces of kit, house lighting sets for example. You could buy (e.g.) a 16-light system, where the lights were of a specified cp, and their power consumption and hence current was inferred. The generator was of a stated output but the newcomer to electric lighting would perhaps not have found that easy to equate with how many lights he could have on, allowing for battery charging etc, hence the nominal rating in lights. But I'm not familiar with GEC using it for plugs.

In those days 16/20cp lamps were common, taking 0.5A on 100V and 1A on 50V. So amps and lamps might be the same, or different - note how no voltage rating is offered for the plugs either. It seems unlikely that many people would have wanted to connect 20 lights to a single socket though.
