Round Pin Mains Power Plug 5 Amp 5A 250V UK British BS546A

This is one item of new, five Amp UK round pin plug. These are still occasionally found in some specialist electrical installations like older theatre lighting systems, holiday cottages in the outer islands, and just occasionally in hospitals or radio stations to keep cleaning equipment away from the 13 Amp standard rectangular pin ring main, or occasionally the other way round. I've also seen them used in modern household lighting circuits where a main wall-mounted dimmer controls various standard lamps dotted around the room.
