This is in relation to an outbuilding with a small single-phase 240V AC ring main, fed by a diesel generator with a remote auto-start feature.
I saw a device advertised which you attach to the ring, and to the generator's auto start signal input. From the advertising info, it seems it applies a low DC voltage from a battery to the ring, and then uses disturbance of that DC supply to detect the plugging-in of a load. It then sends a signal to start the generator to supply full 240V AC supply.
I was wondering though, would all loads designed for operation on 240V AC mains, trigger a detection when plugged into a low voltage battery DC supply?
I'm thinking, a toaster will work because it's just going to present a straight resistance and V=IR will be seen by whatever's in the box, but what about something with a capacitor dropper type design? Like say an LED lamp in a holder on a flex with a UK 13A plug on the end?
What about things like switch mode power supplies? Neon lamps?
